A throwback to the classic M16, complete with 20" barrel, A2 front sight, and adjustable carry handle rear sight. The carry handle is removable, and hides a Picatinny rail—so if you want to convert it, you certainly can. Includes an M16 Bolt Carrier Group and charging handle. The upper is equipped with a dust cover and forward assist. If you've been looking to start a classic M16 build, this is a great place to start!
