أنبوب غاز بطول كاربين AR15 من الفولاذ المقاوم للصدأ + كتلة غاز

The stainless gas tube fit my 0.75" barrel perfectly and the low profile block lined up with the roll pin hole on the first try. Tight tolerances, no wobble once pinned into the front sight. Runs clean after a few hundred rounds.

Swapped this onto my 16" build and the stainless tube mated with the 0.75" barrel journal without any filing or fuss. The low profile block lined up dead center with the gas port and the roll pin tapped in clean. Zero cycling issues after about 300 rounds.

The stainless gas tube and block were a perfect fit on my 0.75" barrel, and the included roll pin made installation straightforward. CNC machining is clean and the low profile block clears my handguard nicely.
