This newly designed solid billet tactical grip is the perfect replacement for the standard strap. Our new design offers a tactical forearm position giving the shooter more control under rapid fire and increased target acquisition. It is hard coat anodized and well constructed from top to bottom in a one piece design with a knurled textured grip. Finished in an anodized black finish, works with stock uppers and most after market uppers as well. Allows enough barrel thread for most suppressors and muzzle breaks and is flush to the exterior barrel base. Easy installation with a clamp design for strength and a set screw for a tight fit. Allen wrench included. Fits standard 3/4x10 & 1/2x28, 5/8x11 (.380) threaded barrels for M-11 SMG & Semi Auto series. Will NOT fit .380 barrels with smaller barrel base lug. Larger lug must be about 1 inch in diameter. Please call if you have any questions. Addition of this item to a semi auto gun may require additional paperwork to be filed with the ATF, check with your local dealers. (gun and other components sold separately)
