Strike Industries Collar Adjustable Gas Block


Some upgrades you do just because they're fun. You change a mag release here or charging handle there for no other reason than just to do it. Then you get into the serious stuff. I don't mean that you need an engineering degree, only that you start to modify things for a purpose. The first step along the way for many is an adjustable gas block.

Hey, I failed Physics!

Don't worry, I'm not going to bore you with a lecture. Just think of the SI adjustable gas block as a way to balance the forces inside your weapon. There has to be enough gas sent back to the BCG to make the gun work. However, too much gas isn't a good thing. If you want to fire a stronger or lighter load, you need to meter the amount of gas available. The same thing goes when you run your gun suppressed. It's all a matter of balance. Too little gas and your gun won't reliably run. Too much and you get increased recoil plus added wear on the internal parts of your AR.

A New Approach

Adjustable gas blocks have been around a long time. However, the Strike Industries collar adjustable gas block makes the process way more straightforward. The SI adjustable gas block has six positions that lock in place with an internal spring-loaded detent. The gas block collar smoothly rotates into position with only the help of the tip of a bullet or a blade. That means you don't have to remember to bring an Allen wrench with you. A Strike Industries collar adjustable gas block lets you match your gun to your needs quickly and without any hassle.

  • Works Great

    4.5 Stars Installed on my DPMS G2 Hunter. Pros - Installation is super easy. This setup works great with an exposed gas block as I can easily turn the color by hand but can’t by accident. Cons – limited number of positions so some buffer adjustments might need to be made. I wish the front was slanted for a better look. In wide open - 7.62 range ammo ejects at 3:30 One down - 7.62 range ammo ejects at 4:30 Two down - 308 180gr hunting ammo at 4:00 Bottom line is that it works perfectly, easy to install, easy to use, could look a little better.

    This is an awesome unit and install is very straightforward and simple. Also like the design for getting aligned with the gas port. Curious to see how the five gas setting work out with various loadings an weapon configurations

    Great product. Installation was straightforward with video instruction (great concept). At the range it worked as expected. Once I get my suppressor and play with the settings, I will re-evaluate.
