Recommendation for a gas block?

[richie3888]

Hi I want to change my gas block/front sights into a gas block with rails. Or just a regular gas block with no front sights. Where is a good place to buy one and which brand should I look for and which brand should I avoid?

Thanks
Richard

JD Machine makes several types, depending on what you're looking for.

Daniel Defense, Vltor, Larue, JP all come to mind as well.

If your new gas block uses set screws I'd recommend one of these.

Maybe not needed but for peace of mind its GTG.

Fixture for dimpling barrel for set screws

I prefer the Daniel Defense clamp on block. It is tiny and it isn't going anywhere. I swore off set screws, but that is because I am always changing things on my AR. If you don't expect to be changing anything the set screws will be fine.

If you want just a flip sight, I like the Yankee Hill Flip sight. So you dont have to buy a gas block and sight. Like this one:

vltor or jp should be GTG.
