BoreBuddy AR22 Adjustable Bolt Weight, Gen 4

BoreBuddy Adjustable Bolt Weight (Gen 4)

Gen 4 is here! It’s everything Gen 3 was, but much more robust and features tool less internal weight adjustment!

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.

CNC machined from solid stainless steel with steel and aluminum inserts for precise tuning for each rifle and load combination, in the same manner as centerfire H1/H2/H3 buffers.

The Gen 4 adjustable bolt weight allows the bolt weight to be fine tuned by adding 1.3oz to 1.8oz of weight (or up to 2.7oz using tungsten internal weights). 

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