How to Replace the Handguard on an AR15

The AR15 is a rifle with a proud American heritage, a proven firearm with a superb blend of accuracy, weight and ergonomics. The AR15 platform is now built by many different manufacturers---Colt, Smith & Wesson, and Bushmaster, among others---and it is one of the most popular rifles to customize. There are several variations of the AR15 today, each with its own options, but the basic core design is the same regardless of the manufacturer. You can replace most components, such as the handguard, the pistol grip and the stock, with virtually any compliant AR15 accessory.

      Remove the magazine, pull the bolt back and inspect the chamber to confirm that the rifle is unloaded, then stand the rifle on its buttstock so the barrel is pointing straight up.

      Remove the old handguard, which on a standard AR15 is held together by a tension ring between the receiver and a cap integrated into the barrel of the rifle. With the AR15 still vertical, firmly grasp the tension ring at the bottom of the rifle and push down. The ring should slide free, allowing you to pull the bottom of the handguard (which is two separate pieces) free from the ring. Repeat the process to remove the second piece of the handguard.

      Install the new handguard. Grip the tension ring and push down firmly. Insert the top end of the handguard against the integrated cap of the barrel on the top end, then slide the bottom of the handguard underneath the tension ring. Once you've positioned both pieces of the handguard, release the pressure on the tension ring and allow it to pop up over the handguard molding.
