Weather extremes cause gun furniture to warp, pushing the barrel out of straight alignment. Don't let the weather affect your performance. Free-floating handguards will not touch the barrel and will not affect accuracy. Get a rifle-length free-float quad rail and nothing touches your barrel no matter the conditions. Pick from a 12-in free-float quad rail or a 13” free-float quad rail to match your needs and style. The rifle-length quad-rail free float can hold tactical scopes, red dots and iron sights canted to one side, along with a laser and a light. You choose. With the AR-15 rifle-length 12” free-floating quad rail, you have plenty of room for all the necessary accessories. Be sure to add the end cap to prevent damage to your handguards. All the handguards sold by Del-Ton fit any caliber in an AR platform. These rifle-length handguards support night-vision optics as well.
