AR-15 前推輔助組件與拋殼口蓋組件

Both pieces fit my mil-spec upper with zero slop, and the ejection port cover snaps shut with a solid click instead of rattling around. The forward assist spring feels stiff in a good way, not gritty like the cheap one I swapped out. For the price of a two-piece kit, I'm honestly impressed.

The forward assist dropped right into my upper with no fitting needed, and the ejection port cover snaps shut with a solid click. Roll pin and spring were both in the bag, so I didn't have to dig through my spare parts bin mid-build.

Bought this for my first AR build and the complete assembly made installation a breeze – both the dust cover and forward assist fit precisely. No surprises, just solid parts that do exactly what they should.
