Hello all, does anyone happen to know of a gas block I'm not going to have to grind on to fit properly under a URX II? I'd purchase the KAC gas block but they're OOS everywhere. This is going on a .750 11.5" barrel.

Thank you in advance.

Sorry read that the wrong way. Shouldn’t a mk12 low pro style gas block work?

You’ll have interference with a mid gas, and a urx2 mid sight portion.

I don’t recall there being any issue with standard lp GBs under the rail itself.

Just disassemble the sight and slide it on.
It goes back together really easy.

You'll need to use a carbine length gas system with the URXII rail.

Not sure why I didn't think of this. Thank you everyone for the replies.

I ended up using an EWS gas block and machined the top .080" or so off so it didn't interfere with the elevation roller on the front sight.

For reference this is a patrol length gas system I'm using. I can see how a carbine gas system would have had more clearance.
