Troy m-lok battlrrail - Troy AR-15 Battle Rail Aluminum M-LOK Free Float Handguard

Receive the rail very quick, even for picking the slowest shipping option, that's a plus for Optics Planet. The rail is awesome. Fit and finish is on par with all of Troy's products and this is not exception. The rail is the perfect rail diameter, not too large and not to small, so the feel as when holding the rifle is great. The rail also fit over Odin Works adjustable low profile gas block that has the shoulder on it. I tried a BCM rail I had sitting around and gas block was touching the rail. Installation was a breeze, however I did have issues trying to install the clamp screws, these clamps would not fit over the gas block and so I had to attach the clamps after sliding the rail over the gas block, this was a pain but not impossible. Great rail at a great price.
