This gun is a Bear Creek (BCA) AR15 complete upper assembly chambered in .350 Legend. This upper assembly has a 16 inch barrel, a carbine length gas system, and a 15 inch M-LOK rail. It will work with any standard mil-spec AR15 multi caliber lower receiver. Bolt carrier group and charging handle are included. This assembly is ready to shoot, just needs a complete lower receiver. The upper is equipped with a Vortex Crossfire II 4-12x44 rifle scope with a dead-hold BDC reticle and is zeroed at 100 yards. The scope is mounted with a Vortex Viper Extended cantilever mount and comes with Butler Creek flip up scope caps. The gun and scope are both in great condition and have only fired about 50 rounds. A 10 round steel duramag is also included with the purchase as well as 4 rounds of .350 Legend (all I have left). The upper assembly and scope were painted OD green and black for a camo pattern. The flash hider, trigger, forward assist and ejection port were all taped prior to painting. The gun runs perfectly and has no issues. * PURCHASE INCLUDES * - Complete AR15 .350 Legend Upper Assembly (BCG and charging handle included) - Vortex Crossfire II 4-12x44 scope - Vortex Viper Extended Cantilever mount - Butler Creek Flip-up scope covers - 10 Round Duramag SS - 4 rounds of .350 Legend ammunition This is well over a $700 value.
