Most Helpful Positive Review Works as advertised.
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 stif...

In principle this adjustable gas block is a good design but there are some problems that make it not function for me, here is the list; 1. The adjuster ring locates against the barrel shoulder, out of three barrels I had, only one had propper gas port alignment with the adjuster ring located agains...

Snapped screws

by GR, from TN, United States Written on April 26, 2025
The 3 screws that clamp block onto barrely snap easily. I torqued mine to spec, shot 1000 rounds, one of the bolts snapped and was missing. Noticed it when swapping handgaurds, couldve happened a long time ago.

SI adjustable gas block

by Davis, Verified Owner from OH, United States Written on January 27, 2025
Installed on a 300 blackout barrel; just what I needed to get the gas system dialed in. Being able to adjust the collar through the Mlok hand guard is awesome. Note: I would be easy on the hardware. No reason to over tighten furring the install. Also, I found if you pull the gas block towards the collar when you are tightening the three torx, it helps keep everything square. The little detent in the face of the gas block, will try to push away from the collar.

I like it enough to recommend

by Reap, from GA, United States Written on January 3, 2025
Strike Industries had a great idea with this adjustable gas block. I think it could use just a bit more fine tuning for it to be perfect. When you put the collar all the way on as it should be the adjuster gets stuck and can not be adjusted. So on mine I had to move it just slightly to be able to adjust it. I want to give it a 5 star but just that issue alone pushes it to a 4.5 for me. Also I don't know if this is just mine so don't pass on this item.
Best Used for:
  • Suppressed and unsuppressed AR15.

work flawlessly after 500 rounds

by Thefingdiabetic, Verified Owner from AR, United States Written on December 27, 2024
Can shut off gas completely or turn it all the way up for unsuppressed shooting. About setting 3 or 4 is perfect for my suppressor. Shut off the gas and you basically have a bolt gun and not a bleed off like some of the others.

Perfect Gas Block

Excellent fit and finish. Installed exactly as described with no issues. Functions as advertised to reduce gas in 6 positions from open to closed. Allows me to cycle my 300blk suppressed, unsuppressed, with or without subsonic. Highly recommend!
