Not really impressed - Presma AR-15 .223/5.56 M-LOK Slim Free Float Handguards

Overall this fit well enough over my 8.5" barrel and .75 gas block. My issue with it is the Picatinny rail. I could not get my Diamondhead Iron sights to slide on (they are a plastic design). I don't really mind a little extra work so i ended up taking a sanding block and some light (220) sandpaper and cleaned up the outside edges of the top rail. I got the sights on, but the rails aren't black on the edges anymore. Getting the locking pin though the sights and the rail we not any easier. So I think Presma's tolerances may need to be tightened up some on this design. In the end it worked, but i doubt i will be buying other Presma products.
