Don’t know what gas block you need? Get this one.

This is a great gas block by a solid manufacturer. I put this on Munoz first build so far, and plan to use it in a second. Light sleek and easy to install. If you don’t know what to buy I recommend this product, if you are an experienced AR builder I hope you try it out against what you normally use.
Good value gas block

Does exactly what it says on the tin. Works as expected on my DPMS barrel. To be honest, the fit was a little tight. Ended up throwing the barrel in the freezer to get it to fit over nicely.
<br>There’s plenty of clearance between this and my keymod handguard. No worries there.
<br>I drilled a dimple into the barrel for one of the grub screws to go into. I doubt this block is going anywhere
