10" free float suggestions.

Building my first sbr (10.5"), and I really like the look of the LMT mrp upper with the smooth rail. I'm trying to find something similar, since obviously they don't sell just the rail. I'm kind of stuck with the DD mk18, or lite rail as far as I've found for 10" rails that aren't too bulky. The reason I'm sticking with a 10", is because once I knocked the A2 sight off of my noveske upper I realized (should have realized sooner) the holes from the taper pins stick out like a sore thumb. I need something to cover them up (without using the troy gb that covers the holes up). Any suggestions?

I'm a fan of the samson evo on my guns.
