22lr Bolt Weight

(3 customer reviews)


Patent Pending

Our new 22lr AR buffer 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.  With a weight, your rifle stays much cleaner, as well.

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

The adjustable bolt weight allows the bolt weight to be tuned from 6.2oz to 7.6oz (using Standard, H1, H2, or H3 configurations).

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 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

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

    I just received my (simple brass) bolt weight. Machining is extremely well done and clean, installation is simple and does not require bolt disassembly. I am headed to the range tomorrow with my wife to test it. Bore buddy packed my order well and shipped quickly.


    Ill save you time. BUY IT. Very well made piece of kit that greatly improves function! bolt bounce has ALWAYS been an issue with 22lr AR conversion kits…well, not anymore. Enter the BoreBuddy 22lr Bolt Weight. its easy to install and remove, but other than cleaning, i don’t know why you would ever want to remove it! completely eliminates bolt bounce and prolongs the life of your extractor, why wouldn’t you want it? as always, another great innovation by BoreBuddy.

    I have a early production brass model and very very happy with it. My AR22 SBR shoots much smoother now and is even more of a joy to shoot. Great Product
