CMMG .22 Barrel & Bolt Kits, everything you need to convert your existing upper to a dedicated .22LR. Just purchase a magazine and you are ready to go.

CMMG .22 Barrel & Bolt Kits

An Easy Conversion to .22 LR for Your Upper Receiver

In this Barrel and Bolt Group Kit, CMMG provides everything you need to convert your AR-15 into a dedicated .22 LR rimfire training platform.

The barrels measure 4.5″, 9″, 16.1″ and 20″ inches long and are machined from 4140 chrome-moly steel, complete with a salt-bath nitride finish and a medium-taper profile. The barrels are optimized with a 1:16-inch twist that’s compatible with most .22 LR bullets on the market, but the system runs best with 36-grain round-nose bullets.

Each .22 LR Barrel and Bolt Group Kit from CMMG also features a .22 LR sporting chamber, as well as a threaded muzzle measuring 1/2-28 TPI thread pitch. CMMG recommends using a round-style hammer in place of a notched hammer to avoid function issues. The only other piece of the kit needed for a functioning system is a dedicated .22 LR magazine.

.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.

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.

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.

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.

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.

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.
