I had been thinking for a while about adding some new uppers to the lineup.  After lots of consideration, testing and working with sample components this is the end result.
Rosco manufacturing makes some really excellent hardware. Combined with top quality products from Aero Precision and Manticore Arms this upper has exceeded my expectations.
Each Aero upper is lapped for barrel fitment and each barrel is scoped during inspection. The Manticore barrel nut is torqued to spec on the 16″ Nitride 1:7 Nato barrel. The gas system consists of a Aero Nitride .750 block and Melonite gas tube in carbine length.
The  Melonite full auto rated bolt carrier group is properly matched to the Rosco barrels. The upper is finished with a Shore Tactical over-sized charging handle and a Manticore Arms flash Hider.
Testing with some Steinel 55gr ammunition provided sub MOA groups.
100% US Made
