Especially helpful in customizing short-barrelled tactical rifles. Machined from bar stock for extra strength and rigidity, then mil-spec Parkerized for exceptional wear- and corrosion-resistance. Low Profile version is a low and narrow, one-piece block designed to fit inside most free-float handguards; allows use of rifle length forearms on carbine length barrels for a clean, streamlined look and added gripping surface. Secures to barrel with included setscrews. Low Profile 2 is shorter and lighter than the Low Profile, and allows rifle length forearms to fit carbine-length barrels.
