I have a factory M&P15OR that came with a pinned and railed gas block. I'm wanting to remove my delta ring / carbine handguard setup and replace it all with a 13" Troy VTAC Alpha and low pro gas block. My build barrel had dimples for set screws. Does the M&P have dimples (doubtful) and if NOT what are the best options?

No dimpels on that barrel, it is pinned on. Have used the clamp on style gas blocks with no problems. Here's YHM's version: LINK

Thanks. I wasn't sure if they needed dimples or not. Been looking at clamp ons. That YHM looks like it's what I need.

I don't have one, but I've read more than one report of this gas block not working with the Troy Alpha/VTAC handguards (too big on the bottom where it clamps). I would do some research on the DD or VLTOR clamp ons and see if one of them would fit.

Fair enough - I stand corrected.

I'm glad you mentioned it though because I hadn't even thought about clearance issues.
