AR-15 上下機匣 MIL SPEC 緩衝管套件 黑色

The ambi charging handle alone was worth it, and the buffer tube kit dropped right into my build without any fitting issues. Castle nut and end plate threads were clean, no burrs anywhere.

Everything needed for the lower came in one bag, which saved me a second order. The ambi charging handle runs smooth and the dust cover snaps shut with a solid click. Buffer and spring dropped in without any wobble.

The buffer tube kit fits perfectly with my build, and the trigger guard is a solid upgrade over standard plastic. Everything was packed together with no missing parts, saving me a headache.
