Set your barrel free with a free-float handguard tube. Free-floating barrels are more accurate than barrels that lay in a channel in the furniture. Wood and synthetics warp in temperature changes and tug the barrel out of line. These tubes are one piece, making them easy to install and remove. The AR 15 carbine-length free-float tube comes in several styles, from Pic rail only on the top and smooth sides to a carbine-length free-float tube handguard with an integral quad rail. Enjoy improved accuracy compared to handguards that attach to the barrel. Appreciate the weight savings of the carbine-length free-float tube compared to traditional AR handguards. With several to choose from, you'll find one that fits your style. Multi-caliber is no problem because these handguards fit over any barrel in an AR platform. The short length is ideal for short-barrel applications and multi-gun tournament enthusiasts.
