What is the AR-15/M16 Upper Receiver Action Block?
AR-15/M16 Upper Receiver Action Block
AR-15/M16 UPPER RECEIVER ACTION BLOCK
Heavy-duty blocks allow you to firmly clamp AR-15/M16 receiver halves in a vise without risk of crushing, twisting, or otherwise distorting them when applying vise pressure or torquing the barrel nut. Keeps your rifle secure for safe, effective cleaning, assembly, and repair. High pressure, solvent resistant, structural Rynite block and insert surround the entire upper receiver and support it inside and out to make rebarreling the AR-15/M16 an easy, one-man job. Lets you firmly secure a mil-spec carry handle receiver or mil-spec flattop receiver in a large bench vise for barrel removal/installation. Torque generated while tightening the barrel nut is transmitted to the block and insert, not the receiver. Minimizes the possibility of damage to the barrel detent pin and receiver detent notch. Holds securely without marring the finish.
DO NOT USE ON BILLET UPPERS OR LEFT HAND UPPERS, OR DAMAGE TO THE UPPER CAN RESULT.
