Good rail w/ slightly out of spec hardware. will have to mod if you're running a thick ar-10 barrel - BOG M-LOK Arca-Swiss Tripod Plate

Does it's job and holds well to ARCA accessories. Biggest complaint is that the mlok nuts are slightly out of spec (camming area a little too large) so you might have to sand those down to get them to rotate the full 90º depending on your handguard. Also if you're running a thicker barrel on your AR-10 you might have to shorten the screws and even the mlok nuts. I'm running a BA Hanson 20" heavy fluted barrel with a 15" handguard and had to modify a few of the screws to clear the barrel and gas block.
