Figured I’d leave a review to share with whoever finds this that the Riflespeed gas block rubs the top of this handgaurd so you won’t be free floated unless you can somehow reach inside to file or grind away the little titties that hang down all along the top of the inside of the rail due to the anti rotation pin needing that space and they extrude it all the way thru. I’m certain the superlative arms piston conversion won’t work either as it’s taller. The internet says the rifle speed will work with these rails and yeah I guess they will but you won’t be freefloated. Other than that it’s very nicely machined and the drive lock feels very strong. Very nice handgaurd and fast shipping! Will order from rooftop defense again for sure thanks!
