Description The Gen 4 deluxe adjustable bolt weight allows the bolt weight to be fine tuned by adding 0.55oz to 1.8oz of weight (or up to 2.2oz using lead internal weights – sold separately). 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. A deluxe adjustable weight is recommended for use with the widest range of ammo, from subsonic ammunition through hyper velocity. See our FAQ, or contact us for questions on your particular application. The weights are designed to fit dedicated rifles and conversion kits with a BoreBuddy/CMMG/RTB/PSA style bolt. Our high frame rate video below shows the effects of adding of each weight type in slow motion.
