.22 Magnum AR-15?

Every so often we receive a message about .22 Magnum AR-15 rifles or .22 magnum AR-15 conversion kits. like always I perform the obligatory research to see if there’s anything new. While there’s often rumors of someone developing a .22 Mag AR or conversion rarely does anything come to market or last if it does. There’s probably a bunch of reasons for this. For starters the value of .22lr AR’s is cheap .22lr ammo, about 7 cents per round.  Alternatively typically for a box of .22 magnum ammo you would expect to pay $10-$17 per box of 50 or 22-34 cents per round. While not expensive your still flinging quarters down range instead of pennies with .22lr. Another reason is 22 mag is a niche market. There is very little interest from the shooting public.

22 Magnum vs 17HMR Ammo

22 Magnum vs 17HMR Ammo

Typically the shooter interested in a .22 magnum AR-15 would actually prefer an AR-15 chambered in the superior .17 HMR. This leads to my final thought, design and engineering. The .22lr AR conversions were proven by Colt and Ciener decades ago. The basic designs of those have been evolving ever since. At this point .22 WMR and even .17 HMR are being built and tested by folks with a passion for the calibers rather than a big manufacturer looking to devote an engineering team to a new product with little interest. Who knows maybe one day this will change but right now shooters are content with their AR-15’s chambered in the .223/5.56, handgun calibers and of course the beloved dirt cheap .22lr rimfire cartridge.

Brandes Magnum Rimfire .22 Magnum AR-15 Upper Receivers

Let me be clear. I have no first hand experience with the Brandes Magnum Rimfire aka BMR uppers. All I know I learned from their website. I have duplicated the information below.

Ray-Vin Brandes Magnum Rimfire 22 Magnum AR-15 Uppers Barrel Feed Ramp

Ray-Vin Brandes Magnum Rimfire 22 Magnum AR-15 Uppers Barrel Feed Ramp

It appears that the BMR utilizes a unique side charging upper. The charging handle and ejection port are two separate cut outs as opposed to the single cutout on an AR upper like a Fulton Armory Side Charger. The BMR blow back design uses a custom bolt and recoil system. Like a Milspec AR-15 the proper buffer and spring are buttstock dependent. See the bottom of this page to view the correct Brandes buffers. The barrel has an extended feed ramp for use with Black Dog .22 Magnum AR magazines.

If you own the BMR Send us a message.

BMR Notes, a lesson in blow-back actions.

Performance: The BMR is a blow-back action. This type of action involves a balance of many factors such as cartridge power, case geometry and bolt mass. In the AR system, the bolt, the buffer and half of the spring weight constitute the bolt mass. Altering the mass of the buffer allows for tuning the action for a particular cartridge.

BMR 22WMR uppers function quite reliably using ammo with 40gr or heavier bullets.

Bullets lighter than 40gr, especially 30gr, will probably require some adjustment for satisfactory results.


It has come to our attention that CMC triggers do not perform with our upper system. Light strikes is the problem reported with CMC triggers. The CMC trigger is engineered to work with AR-15 rifles firing 5.56 Nato or .223 Remington cartridges, and is not intended to work with other cartridges. The fine folks at CMC have told me they will replace the hammer spring with a stronger one at no charge.
If you are ordering a CMC trigger for our upper, call in the order and request a stronger hammer spring. While this may reduce light strikes, there is no guarantee either from CMC or Ray-Vin. We test our uppers using mil-spec triggers and hammers.


.22 Magnum AR-15 Buffers

.22 Magnum Full Length Buttstock A2 Buffer Configuration

Full Length Buttstock A2 Buffer Configuration – .22 Magnum

In the above configurations, the topmost is standard with the CAR recoil spring for 22WMR and 17HMR ammo. The lower configuration uses the standard A2 buffer with a travel limiter. Use this configuration if you experience case head doming or excessive un-burned powder in the action. The travel limiter is necessary to prevent the bolt handle from bottoming in the receiver slot.

.22 Magnum Carbine Length Buttstock A4 Buffer Configuration

Carbine Length Buttstock A4 Buffer Configuration – .22 Magnum

Similar to the A2 configurations, the uppermost is standard and the lower should be used if you experience case head deforming or excessive powder in the action.

       

TACTICAL INDUSTRIES TARGET MASTER AR-15 22LR CONVERSION KIT

TACTICAL INDUSTRIES TARGET MASTER AR-15 22LR CONVERSION KIT

The Tactical Industries Target Master AR-15 22LR Conversion Kit is a drop in, blow-back activated device designed to adapt the M16/AR15 family of weapons to fire the .22 long rifle cartridge. The Target Master conversion unit installs in less than 1 minute without the use of tools. The Target Master conversion unit allows the use of inexpensive .22 long rifle ammunition in lieu of expensive 5.56mm ammunition. The Target Master is designed to replace the standard bolt group without any permanent modifications to the weapon. It will not change the appearance, feel, weight, handling; nor will it affect the performance or operating procedures when the weapon is utilized in the semiautomatic mode. The Target Master comes with one 30 round magazine. It has the approximate shape and unloaded weight as the standard 30 round 5.56mm magazines designed for the M16/AR15 family of weapons.

TACTICAL INDUSTRIES TARGET MASTER AR-15 22LR CONVERSION KIT

TACTICAL INDUSTRIES TARGET MASTER AR-15 22LR CONVERSION KIT

The Target Master allows an accurate alternative to full power 5.56mm practice and training which can be carried out in indoor shooting ranges or on limited distance ranges within city limits with .22 long rifle ammunition.Our tests prove that at 25 meters, groups were consistently between .50 – .75 inches and fell less than .50 inch below the high-powered 5.56 groups on the target.

The Target Master is an excellent tool for weapon familiarization and training for new shooters without the muzzle blast, noise and recoil associated with full power 5.56mm ammo while allowing the use of real full size weapons. Good weapon skills are developed by repeated practice building muscle memory. Target Master allows you to shoot more and shoot more often.

TACTICAL INDUSTRIES TARGET MASTER AR-15 22LR CONVERSION KIT CASE

TACTICAL INDUSTRIES TARGET MASTER AR-15 22LR CONVERSION KIT CASE

The Target Master allows continuous practice without damage to your weapon. Soft lead .22 long rifle bullets do not reduce barrel life like the full power 5.56mm ammunition. Practice with the Target Master will extend the life of both personal and LE agency weapons for many years.

The Tactical Industries Target Master AR-15 22LR Conversion Kit is proudly made in the United States of America by Americans with materials produced in America.

TACTICAL INDUSTRIES TARGET MASTER AR-15 22LR CONVERSION KIT ACCURACY

  • The Target Master Conversion Unit has proven to be very accurate in all weapons tested. The weapons tested to date include the Colt, CMMG, Bushmaster, DPMS, Model-1, Olympic Arms, Rock River, Stag, and Smith and Wesson.
  • We have tested most different types of .22 long-rifle ammunition in our Conversion Unit. The most consistently accurate results were obtained with standard and high velocity ammunition weighing 36-40 grs. Copper coated ammunition, while not more inherently accurate, allows for longer shooting sessions of acceptedly accurate fire between clearings. Take a look at our .22lr Ammunition Types and Brands Comparison Gallery.
  • The accuracy of our conversions unit is suitable for zeroing weapons. Battle sight zero is obtained at a distance of 25 meters using the procedures in the army publication TM 9-1005-149-10. At ranges up to 50 meters, the .22 long-rifle cartridge produces approximately the same trajectory as the 5.56mm cartridge. At ranges 75-125 meters the .22 long-rifle ammunition will require hold off aiming.
  • While firing from 25 meters, our Conversion Unit easily shot groups of .50-.75 inch with most ammunition’s tested. This is equal to or better than the 5.56mm tested at the same distance. The .22 long-rifle groups printed less than .50 inch below the standard 5.56mm groups.
  • All ammunition and rifle combinations produce different accuracy results. We suggest you try several different types and brands of ammunition in your rifle to discover its maximum accuracy potential.

Q: What is the recommended cleaning process when using the Stag Arms .22 conversion kit?

A: After every 500 rounds, 3-5 shots of 5.56NATO ammunition need to be shot through the rifle to clear out any lead fouling. Immediately after shooting, the .22 conversion kit should be removed from the upper half and it should be cleaned as soon as practical.

AR-15 22LR Conversion Kit – Back in 2006 or so I created this page for one of our other sites Combatrifle.net now Combatrifle.com. Timing was right as the “Tactical 22’s” were just coming on to the scene. While shooters embraced the airsoft knockoff .22’s  other shooters particularly AR-15 shooters began to embrace AR-15 22 Conversion Kits. This page became massively popular. Now in 2017 as I copy the page to this site I’m struck by how much the AR-15 22LR Conversion Kit landscape has changed. Most of the information on this page now only serves historical value.

Drop-in AR-15 22LR Conversion Kit:

Read the history of the AR-15 22lr conversions here

The Drop-in AR-15 22LR Conversion Kits are the easiest and least expensive method of converting your AR-15 to a .22 caliber plinker. The kits will range in price from about $160-$250 and take about 30 seconds to install. There is a few down sides to using the drop in kits. The bullet must travel a few inches in an unrifled tube before it reaches the barrel. The barrels on most AR type rifles will typically have a twist rate that is optimized for the 5.56 Nato (.223) with a 1:7″- 1:9″ barrel twist rate and not the 1:16″ that works well with .22 long rifle. There is also a few thousandths of an inch difference in the bullets diameter of .22LR (.222) vs 5.56 Nato (.224). Those differences can lead to less then match grade accuracy in an AR-15 but the accuracy is perfectly suited for plinking. If that accuracy is not suitable you can purchase a complete .22 long rifle upper. The cost starts at about double of the drop-in conversion and can go upwards well over $1000. The choice is yours.

I purchased my Colt brand conversion kit part# R6222 back in the early 90’s without much fanfare. The Colt and the Jonathan Arthur Ciener kits seemed to be the only ones around at the time, at least that was my findings in the Shotgun News and prior to the internet. Recently a good friend purchased his first rifle, a Bushmaster Modular Carbine. I explained to him the virtues of cheap practice ammo, getting to know the rifle and the ability to shoot at any indoor range. Eager to get a conversion kit he quickly hit the web with google and met a brick wall in a lack of availability. My friend got quickly frustrated so I decided to do some research the result of which you are reading here. A few things came to light very quickly.

The Colt unit I own while listed as a current product offering is nowhere to be found. The Jonathan Arthur Ciener kits are being offered at several places for low prices but none are in stock even at his own site .22lrconversions.com. Jonathan Arthur Ciener has always had a long back order and a history of poor customer service. He also has quite a few complaints against him at the BBB. In fairness everybody seems to get their kits just be prepared to wait. In the end my friend ended up ordering a CMMG AR-15/M16 22LR BRAVO CONVERSION KIT from Brownells Update 2015:(When this article was originally written the word “Bravo” was not part of the name

.22LR AR Upper Receivers

Now if after reading the above you feel you need more from a .22 conversion a complete upper chambered for .22 long Rifle is exactly what your looking for. You will be able to achieve greater accuracy and superior reliability with these dedicated uppers. These units start at around $450 with the sky being the limit. The low end units typically will look like any other AR15 with a typical handguard and a carry handle or flat top receiver. What starts to drive the costs way up is the barrels. Some manufacturers offer custom match grade barrels. These barrels turn the AR15 into a fine precision shooting machine with accuracy on par with other top rifles in the .22 Long Rifle class. Take a look at this Lakeside Guns for what is probably the most radical 22lr AR-15 dedicated upper receiver to date.

Tips:

  • Keep the drop-in units cleaned and lubricated
  • Inspect the gas tube for fouling before returning the weapons center fire bolt carrier.
  • If you get failures to extract often, clean the area under the extraction claws. It has probably become dirty and the claws are not returning to their fully retracted position
  • Failure too feed will be from the magazine and or carbon buildup on the neck of the carrier preventing it to fully seat in the chamber
  • Failures to fire, see above. The carbon prevents the the .22 bolt from seating firmly. Energy is lost from the firing pin and light strikes can result
  • Ammo – These things can be fussy and cause either of the two previous problems. I’ve found high and hyper velocity ammo to work best.

CMMG AR-15 22 Conversion Kits

August 22, 2010 – CMMG is growing their .22LR lineup by leaps and bounds. They have added Stainless Steel and Left Handed versions of their popular AR-15 conversion units as well as dedicated .22LR Uppers and Complete Rifles ,22LR. There are also many more models to be released over the next few months. CMMG is also adding accessories unique to these .22’s as well as possibly firsts in the shooting world. The first item is the Anti-Jam Charging Handle for Drop-In Conversion .22. The charging handle is machined much more shallow that that of an AR-15. This prevents a .22 case from getting jammed inside the upper.

Range Report: We received our CMMG kit approximately 2 weeks after ordering it directly from CMMG. The unit was well made and fit our brand new Bushmaster Modular Carbine perfectly. A quick trip to an indoor range for some informal shooting and we were very pleased. We put 300 rounds of inexpensive Federal American Eagle .22 through the Bushmaster with only one failure to fire. The rim of the cartridge was struck firmly so I fault the cheap ammo and not the conversion kit. Feeding and extraction were perfect with no failures. Accuracy was better then we expected at 25 yards with the Bushmaster sporting a 1-4x Millet DMS Scope. Shooting from a bench we could easily blast out the blast out a 1″ circle all day. The kit is probably capable of better accuracy then that but the trigger on the Bushmaster is a little stiff. We will compile a real review at a later date.

A “blowback” operating bolt is machined from lightweight aluminum for great durability, and all parts are easily disassembled for cleaning / maintenance.

Compass Lake CLE AR22

Here’s a little info from the Compass Lake web site. “We use the Army’s M-261 kit because it has proven to be the most reliable of all the kits we tested. The M-261 kit will allow single loading as the bolt will lock back after each shot when used with a standard .223 magazine. The M-261 magazines are insert magazines that fit into a standard .223 magazine. The bolt will not lock back automatically on the last shot with the .22 insert magazine installed. The bolt can be manually locked back with either. The upper receivers are supplied with two magazines and one single round loading device (LED). This device enables you to insert a single round into the chamber to make it possible to single load the rifle.

We use Douglas stainless steel 1-16 twist rimfire barrel blanks. The cartridges chamber directly into the barrel. The chambering reamer is a JGS match reamer that is very similar to the Bentz reamer. The service rifle uppers are equipped the same as our .223 service rifle uppers with float tube and 1/2 moa or 1/4 moa match sights with interchangeable apertures and hood. Most shooters choose the 1/4 moa rear sight for the fine adjustment it offers. Space gun uppers are also available either in flat top/A4 or modified receiver configuration. Krieger rimfire barrels are available for an additional $112.20

DPMS AR 22

The original DPMS conversion kit is the same as the Colt unit. It is no longer available. I cannot seem to locate if DPMS is currently offering a kit but they is offering complete uppers

DPMS CMP22LR AR-15 22

Based on my research DPMS made at least two different dedicated .22lr upper receivers. From the images Ive seen they look very good and appear to utilize the Colt style magazine and modified Colt bolt carrier. This would make sense as mentioned above DPMS once offered a DPMS branded Colt 22lr conversion for sale.

SPIKES TACTICAL .22LR CONVERSION UPPERS

Spikes Tactical offers a few different variations of complete upper receivers as well as .22 LR conversion kits. The conversion kits look to be similar to the CMMG and Ciener units. Differences: notice the o-rings for a better chamber seal and chrome plating for smoother function and easier cleaning. The Spikes unit cost more then the competitors but its worth the premium in my opinion.

Something that sets Spikes Tactical apart from the others is they offer the parts to build your own .22 LR AR-15 starting with a caliber stamped “.22 long Rifle” stripped lower receiver. Pretty unique.

CMMG MK4 HT 22 AR15 UPPER RECEIVER

CMMG MK4 HT 22 AR15 UPPER RECEIVER

I have been following CMMG’s progress with their .22LR AR22 line of hardware since the SIERRA was announced years ago. I bought the SIERRA and have been enjoying it since. By most reports the overall quality of CMMG products has improved in the last couple years. Perhaps I will order the MK4 HT and see how it compares to it’s older sibling SIERRA.

CMMG MK4 HT 22 AR15 UPPER RECEIVER – the CMMG MK4 HT dedicated .22 LR AR15 FLATTOP UPPER RECEIVER lets you do live-fire training with affordable rimfire ammo while retaining the weight, balance, and feel of your rifle. Replace your existing upper with the AR22, load the included Black Dog .22 LR magazine, and you’re ready to shoot. You practice with your existing trigger and fire control components, so the trigger pull feels the same. The mil-spec receiver has a standard MIL-STD 1913 Picatinny rail, charging handle, forward assist (non-functioning), and ejection port cover. Inside, the standard bolt/carrier assembly is replaced by a dedicated “bolt rail” of hardened tool steel with a blowback operated stainless steel bolt inside. Both components are built to run hard and handle the abuse of long practice sessions. M4 has the appearance and weight of a USGI M4 upper, with correct contour barrel, standard M4 handguard, A2-type flash hider, and a gas block/front sight tower with bayonet lug, sling loop, and square front sight post.

When modularity, accuracy and quality are all important, the Mk4 HT is the rifle of choice. The CMMG MK4 HT 22 AR15 UPPER RECEIVER features CMMG’s RKM11 KeyMod free float hand guard. Either a 416 stainless or nitrided 4140 CrMo steel barrels in a heavy taper profile are offered in 5.56mm and 300 BLK. The 22LR model is only available in the nitrided 4140 CrMo type barrel.

  • Caliber: 22 Long Rifle
  • Barrel: 16 inch 1:16 twist rate, heavy taper, 4140 CrMo, SBN
  • Muzzle: thread protector, threaded 1/2-28
  • Hand Guard: CMMG RKM11 KeyMod handguard
  • Upper Rcvr: Forged 7075-T6 AL M4 type upper
  • Trigger: Single stage mil-spec style trigger
  • Weight: 7 lbs (unloaded)
