Adams Arms 16″ Carbine 5.56 Piston upper with a Magpul MOE Guard installed (Gray).
In our opinion, Adams Arms makes one of the finest AR-15 uppers on the market today. Their piston system increases reliability, reduces maintenance, and decreases felt recoil. Their system is simple and intuitive, making it easy to clean and take care of. The melonite coating on their barrels is a significant upgrade from the chrome lining used on most barrels, offering both improved performance and increased barrel life. Fit these uppers to any quality AR-15 lower and experience a new level of AR-15 performance. These uppers come with the complete bolt carrier group These uppers come with a standard AR-15 charging handle The gas block is pinned The muzzle device is a standard A2 and it is not pinned Adams offers a lifetime warranty and we have had great warranty support from them We recommend the Magpul MOE M-LOK Handguard, the Yankee Hill 2-Piece Piston Quad Rail, and the Daniel Defense Omega Rail for these uppers. There are other compatible options.
