CMC Triggers AR-15 Free Float M-Lok Texan Handguard 10.5in Black Medium. At 10.5 inches this handguard designed to give you room for a light and a hand stop without crowding your support hand. The tube is precision machined from 6000-series aluminum so it's light without feeling flimsy. A knurled 1018 steel barrel nut holds it steady and stainless mounting screws with a black oxide finish won't rust on you. M-LOK slots run along the sides and bottom. The top is MIL-STD-1913 Picatinny and the whole thing wears Type III hard coat anodizing.
