Subject pretty much says it all.
I’m considering a build that will use the Vltor clamp-style .625 gas block and a low-profile handguard.
I don’t know what hand guards will fit over it. (the UTG Slim Pro is tempting) Using the Vltor clamp style because…no reason not to and it seems to be a good product. (Installed one once before)
I searched but it’s looking like a make-sure-you-can-return-stuff kinda deal.
I do not recommend using clamp on gas block. Get one that uses set screws and use a barrel that is dimpled.
Along the same line as the OP, anyone know a free float handguard ( preferably keymod) that’ll fit on a LWRC M6? I’m pretty sure I’ve seen that the Rainier Evo would, but are there other options out there?
I appreciate the advice. I’ve also found many builders who advise the clamp on is more secure than the dimpled set screw. But they also say there is nothing wrong with the dimpled set screw.
What I’m not reading or seeing is many stories about properly installed dimpled set screw blocks and clamp on style blocks coming loose. It appears that in the real world both methods normally work just fine.
A clamp on is not more secure. You can use the search and probably find multiple discussions about the topic.
I’m just gonna put this here:

Cool. I have seen it and still doesn’t change anything. I have seen several instances of the screws that have broken, and blocks that have come loose.
Just thought I’d update the thread.
I ended up with a Troy Alpha rail and .750 barrel. Looked like a real tight fit so I used a set-screw type gas block. I doubt a clamp style would fit with it’s side-screws.
I dimpled the barrel myself (wasn’t hard, just took my time and did it right) for the rear of the two screws. Everything seems okay but need a BCG so no firing yet.
