For sale is a Bushmaster ACR chambered in 5.56mm nato with a 16.5in barrel. The barrel has around 1500 rounds through it and has a POF-USA triple port muzzle brake. This rifle functions very well and has had no issues. Some of the upgrades are. a Nexus Tactical AML-1 carbon fiber lower receiver (the original lower does come with the rifle). a Franklin Armory BFS3 ACR-c1 binary trigger ( the original trigger comes with the rifle). Dual charging handles, forward grip, a two point sling, and spare parts. $2800 cash. would consider a trade for a ruger mark 4 22/45 lite or tactical with cash or a winchester 30-30 lever action rifle with cash. Iron sights not included. I also have a 14.5" and 10.5" barrels for the ACR if interested for a additional cost.
