Works as advertised. - Strike Industries Collar Adjustable Gas Block

Purchased to update an existing rifle. The gas block is nicely machined. Installation was straightforward after watching the Strike Industries video as there aren't any instructions included. There arent any rubber o-rings, but the machining tolerances are tight. After installing the detent was stiff but has loosened up with use. The adjustments are pretty easy to get to when under a handguard with the use of a round or whatevers handy. The ports work as advertised with closed not cycling the bolt and fully open letting all the gas through. It's only seen roughly 200 rounds so only time will tell how it will function long term.
