Henry Y. ★★★★★

Wasn't sure a budget kit would feel this solid, but the buffer tube threads went in clean and the stock locks up tight with zero rattle. The mil-spec fit is spot on for the price.

Joseph ★★★★★

Finally got this mil-spec kit on my build and it locks up tight with zero wobble. The buffer tube threads were clean and the stock slides smoothly—exactly what I needed for a reliable setup.

Scarlett V. ★★★★★

The stock and buffer tube installed perfectly on my lower receiver, and the mil-spec dimensions mean zero play once tightened down. Exactly what I needed for a clean, reliable build.
