Good value gas block

by -

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

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.
