Rimfire World website project to upgrade a CZ 452 AMERICAN rifle
CZ 452 American Rifle
CZ 452 American, project “Ernie” – Dedicating this project to Ernie “Microgunner” Simms who passed 2015. Ernie was my number one enabler. Ernie worked in a pawnshop in Florida and was always giving me dibbs on what came through the doors. Ernie also had an amazing knack for turning my statement of “I wish I could find a . Aside from his gun finding abilities Ernie was very knowledgeable;e about firearms and a dare call him an “Expert” in all things .22. It’s difficult to look in my safes and not see Ernies fingerprints on much of the contents. Ernie was 100% responsible for every part on this page except the silencer and scope. I miss my friend, RIP Microgunner.
Distracted by the monstrous success of 308AR.com I was a little late jumping on the CZ 452 American bandwagon for a tactical22.net (now Rimfire World) project. It wasn’t until my friend Rob mentioned the CZ rifle that I learned of this little gem. It seems that CZ quietly introduced a beautiful bolt action .22lr rifle aimed squarely at American shooters with its 16″ threaded barrel. The quality, superb accuracy and of course the threaded barrel created quite a stir among shooters. It wasn’t too long before shooters saw a potential to convert the CZ to a trainer rifle.

Before the Spectre II hit the market, users had to choose between an easy-to-clean monocore suppressor, or an extremely quiet K-Baffle design.
SilencerCo changed that with the Spectre II by pioneering their Click-Together baffle system; which provided nearly the same performance as a true K-Baffle as well as the easy maintenance of a monocore. As a result, the Spectre II was an instant success!
The Spectre II was an incredibly influential silencer. As a result, you’ll find that most of today’s modern rimfire designs have continued to build on its best elements with newer & better features.
Thanks to the Spectre II’s innovation, there has never been a better time to be in the market for a rimfire suppressor!
From the Manufacturer
With its construction of ultra high performance and tough Stainless Steel, the SilencerCo (previously SWR) Spectre II allows weapon fire to go virtually unnoticed. It is not only super tough, but also one of the quietest 22 suppressor known to man. With the Spectre II, users will also enjoy its multi-caliber versatility.
CLICK TOGETHER ASSEMBLY (CTA) BAFFLE STACK
The Spectre II has a unique CTA baffle design for easy disassembly and is user serviceable, which is very important for any .22 lr silencer.
Because the .22 lr round is not copper jacketed, molten lead and carbon debris will explode into the silencer when the projectile exits the muzzle. After some time it is possible for a .22 suppressor to fill completely with lead and become heavy and ineffective.
To avoid this issue .22 silencers must be able to be disassembled for cleaning and regularly maintained. Most .22 silencers on the market can be disassembled for cleaning, however they require cleaning every 50 to 200 rounds or often times they will fuse together and they are unable to come apart. When the lead and carbon debris adhere to the inner wall of the silencer tube and fill the spaces between the baffles and the tube, there is simply too much build up of fouling and lead to remove the tube from most .22 lr silencers on the market.
The Spectre II has the unique CTA baffle design that keeps the carbon and lead debris from reaching the silencer tube allowing it to be disassembled easily.

TIMNEY 452L CZ 452 AMERICAN AFTERMARKET TRIGGER
The TIMNEY CZ 452 AMERICAN TRIGGER is one of the few trigger options for the CZ 452 and maybe the only modular drop in at this time. The only drawback with the Timney is that different stocks will require different modifications to accept the Timney. Not a big deal though. It’s less risky and stressful than balls and springs flying about.
DIVERSIFIED INNOVATIVE PRODUCTS DIP CZ 452 AMERICAN 3/8 PICATINNEY SCOPE MOUNT
To my knowledge this is the only scope mount option available for the CZ 452
CZ dovetail scope rail is available in a mount just for the CZ rifle. Produced from high quality 6061 aircraft aluminum on computer controlled milling machines. Mil spec hard anodized for a long lasting finish. Slides onto the dovetail and easily attaches with the six(6) supplied set screws that, unlike a 4 screw system, allows you to level the rail BEFORE you install your optics. No drilling or tapping required. Adds approximately .220″ to the receiver height Low profile allows you to remove your optics and still see your iron sights if so equipped 5 MOA(slope) built in so if you want a 100yrd zero your scope will be almost centered in it’s adjustment range but still easily adjusts to a 50yrd “zero”(or less) if you need or you want to.
- 6061 Aircraft Aluminum
- Set screw Torque – 6-7in pounds
- Mil Spec Hard Coat Anodized
