Strike Industries Advanced Receiver Extension Buffer Tube - SI-AR-ARE-T7
Strike Industries Advanced Receiver Extension Buffer Tube Black One Size
The Strike Industries Advanced Receiver Extension is a 7.28 in seven-position tube machined from 7075-T6 aluminum at the 1.145 in mil-spec stock diameter. Scalloped flats cut friction against tight-fitting stocks, the buffer retainer boss is supported, and the internal length matches a standard carbine extension, so it runs carbine buffers and springs.
