22lr Simple Stainless Bolt Weight



Our 22lr AR bolt weight system reduces bolt velocity, delaying case ejection and reducing the volume of gas and powder residue released from the ejection port, while eliminating the infamous 22lr AR bolt bounce.  The bolt weight engages our bolt buffer at the rear of the BCG, further reducing noise and harshness for a truly refined and reliable system.  Additionally, with a weight installed, your rifle will stay much cleaner.

If your barrel is less than 8″ long or you use subsonic ammo, the lightweight adjustable bolt weight might be a better fit.  Click here for that product.

WARNING: DO NOT use the bolt weight with bolt groups produced in the 1980s that have a sheet metal firing pin.  Please click here for details

The stainless steel bolt weight increases the 22lr AR bolt weight to 6.3oz

Please note: There are a lot of variables in cycling of the AR22 platform, with ammunition selection being the largest of those variables.  Significantly reduced power ammunition (CCI quiet, etc.) is generally not recommended and tuning the system for reliable cycling with your particular load may be required.  An adjustable weight is recommended for use with the widest range of ammo, from subsonic ammunition through hyper velocity.  The heavy duty weight is the “all around” choice and is designed around using bulk pack high velocity ammo.  See our FAQ, or contact us for questions on your particular application.

For reference, the Ruger 10/22 bolt is 6.2oz and Marlin Model 60 bolt is 5.9 oz

The weights are designed to fit dedicated rifles and conversion kits with a CMMG/RTB/PSA style bolt.

WARNING: DO NOT use the weight with early production Atchisson/Ciener bolts with a rectangular/flat firing pin.  Please click here for details
