The Colt Expanse M4 carbine was introduced in 2016 with the addition of a forward assist and dust cover. The new Expanse model puts a Colt quality AR-15 within easy reach of the modern sportsman looking to enhance his or her collection, or the first-time buyer looking for a starting point on which to build their dream modern sporting rifle. Either way, the Expanse M4 in 5.56 x 45 NATO (.223 Rem.) is a great way to add another Colt to the stable.
