Spike’s Tactical 5.56 NATO Upper Build Assembly with BAR2 Rail

The Spike’s Tactical 5.56 NATO Upper Assembly features a 16″ Barrel with a 9″ BAR2 Rail.  First, starting off with quality products is the key to a good build.  The Forged Upper Receiver is made from 7075-T6 Aluminum.  Also, tucked inside you will find a M16 Phosphate Coated Bolt Carrier Group.  Before leaving the Spike’s Tactical Facility the BCG is high pressure tested and magnetic particle inspected.  The Barrel is Chrome lined and has a 1 in 7″ twist rate.  It is chambered in 5.56 NATO which can shoot both .223 Remington and 5.56 NATO rounds safely and accurately.

Spike’s Tactical did it again with the BAR2 Rail!  This sleek and sexy rail is perfect to finish off your barrel.  This 1-piece Quad Rail is machined from 6061-T6 Aluminum and Hard Coat Anodized in Black.  The BAR2 (Big Ass Rail) allows for excellent heat ventilation and the anti-rotation tabs keep the barrel nut and rail from coming loose on you.  Lastly, included with this upper assembly is a MIL-SPEC charging handle and A2 Flash Hider.
