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