For AR-15 PCC guns with barrel lengths of 8” up to the typical 16" carbine, we recommend our heavy damped buffer/spring combination with our heavy damped 9mm hydraulic buffer (Part# RB5015HD) and the SPRINCO Extra Power AR-10 carbine buffer spring (color code ORANGE - Part# SPRINCO-25762). This set up is an exceptional package and runs great with everything from light match loads to full power defense loads. Will make a significant reduction in recoil impulse and shot recovery time for super fast and smooth shooting. Used by military and world-class competition shooters world-wide. This is simply the best performing AR PCC buffer system available. You will love it!
