Description The lightweight adjustable bolt weight allows the addition of .55oz to 1.1oz of weight while offering great bolt bounce elimination. The lighter aluminum body allows the user to use heavier internal weights for superior bounce mitigation when using short barrels and/or light ammo. Includes aluminum and steel 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. A lightweight adjustable weight is recommended for use with short barreled builds and/or reduced power ammunition in a longer barreled build. The weights are designed to fit dedicated rifles and conversion kits with a BoreBuddy/CMMG/RTB/PSA style bolt. See the high frame rate video below for a comparison of each weight in slow motion.https://www.youtube.com/watch?v=T_yFO2lUg1A
