STRIKE INDUSTRIES - Collar Adjustable Gas Block

Easy to install ... and work awesome just make sure you stick to the torque values as provided.

I bought this because I like to use a can while hunting. I have a short Odin works Handguard on an A.R. 10, so I can adjust the gas block by hand. I can go from suppressed to unsuppressed easily. This is a good design and I will buy another one.

Worked great on my .300 blackout running a suppressor, great build quality and easy to adjust.

The first one I bought worked ok for about 400 rounds and then I had to take it apart to clean it. The detent for the adjustment stopped working before that. Gas leaks into the mechanism and down the barrel. I bought a second one unfortunately before I realized this. The main design flaw is that the clamping screws are too small, #4-40. The instructions say set screws 20in/lbs. First of all they arent set screws, they may have a different model and gave the wrong instructions. Second a #4 screw will not take 20in/lbs. Loctite isnt a good alternative to #8-32 screws. You have to take it on and off to clean, you are going to break a screw off in it. The gas block gets hot, loctite doesnt hold up to heat. Either way its a dumb idea. I wouldnt buy any product from this brand. Engineering is really poor.
