Bushmaster has designed a rifle for the serious DCM Competition Shooter. The DCM Competition Model combines all the features seen as modifications by High Power Competitors to create a rifle that can help you win right out of the box. In keeping with DCM (Department of Civilian Marksmanship) High Power Competition Rules, this rifle looks like a stock AR-15 type rifle, but includes all the modifications and upgrades that will give you a competitive edge. The DCM comes with a heavy 20" match-grade, button-rifled barrel with a 1 in 8" twist that provides shooters with the accurate start they need. The DCM's buttstock features a 3.62 lb. lead counterbalance weight and the Stay Straight dual aperture rear sight has been modified to accept four sizes of aperture. The two-stage competition trigger has been factory set for a 3.5 lb. first stage and a 1 lb. let off, per CMP/NRA competition regulations. The rifle ships with a lockable hard case, an operator safety manual, a chamber flag, a sling, and two 10-round magazines.
