Mounting a free float handguard on an AR-10 rifle is a popular upgrade that can improve the accuracy, ergonomics, and overall performance of the weapon. A free float handguard does not contact the barrel of the rifle, which means that it is not affected by the heat or vibrations of the barrel. This can result in improved accuracy, especially when shooting from a benchrest or other stable position. Free float handguards also provide a more comfortable and ergonomic grip, which can be especially beneficial for shooters with large hands or those who shoot for extended periods of time.
There are a few different ways to mount a free float handguard on an AR-10 rifle. The most common method is to use a barrel nut, which is a threaded ring that screws onto the barrel of the rifle. The handguard is then attached to the barrel nut using a series of screws. Another method of mounting a free float handguard is to use a clamp-on system. This system uses a series of clamps to attach the handguard to the barrel of the rifle. Clamp-on systems are typically easier to install than barrel nut systems, but they may not be as secure.
