Quality low profile gas blocks

[rugerla1]

I know many of you have built a lot of uppers, just curious which low profile gas blocks you think are the best quality.

If you want non adjustable, the YHM clamp on gas block is the best I have used for money spent.

If you want adjustable, I'd use no less than this one from Syrac

Either way, I never use plain set screw blocks. Clamp on is definitely the way to go.

Thank you for the info and links. I don't have any reason at all to back this up but I'd steered away from the clamp on just because it didn't seem like it would hold its place as good as set screw set up. But the more I read, and I've been reading a lot, there are many people who use them.
Of course you will hear some people say don't use them, but who knows if they've even tried them. That's why I wanted to ask here from people who'd actually used them.
I know I could send off and get one drilled and pinned, but looking for do it myself options. Edited June 9, 2015 by rugerla1

No issues whatsoever with the Troy Low Profile 173ABN helped me put on.  Put about 60 rounds downrange with it two weeks ago.

Anything steel will be better than anything aluminum. Now I prefer clamp on versus setscrew as the method of attachment. Clamp on provided nearly 100% coverage while setscrew types rarely provide 50% coverage. Of all the gas blocks I have seen leak between the block and barrel setscrew types are at the top of that list.

I use clamp on because I've had 2 set screw types come loose on me. Never once in the over 20 something AR's I've built have I had a clamp on loosen up on me. I shoot the AR's I own...a lot.
