Strike Industries Advanced Receiver Extension Buffer Tube - SI-AR-ARE-T7

Strike Industries Advanced Receiver Extension Buffer Tube for AR-15/AR-10 platforms. Machined from 7075-T6 aluminum, it features a 7-position MIL-SPEC diameter buffer tube, fits onto any standard AR-15 receiver, and provides finer length of pull adjustment. Internal length of the buffer tube is the same as a standard carbine buffer tube. Note: not compatible with rifle length buffers or rifle length springs and cannot work with the A5 buffer system.
