The 5.56 Midlength Base 16" Upper is a standard mil-spec upper that incorporates the patented Adams Arms technology and the m4 style handguards. The midlength piston system will give you the benefits of a longer forearm by giving the user a longer, more ergonomic grip, a longer sight radius between the front and the rear sight for quicker sight acquisition and less felt recoil. The piston system parts and the barrel have been treated with our salt nitride Meloniting process making them harder and more corrosive resistant than hard chrome. With the patented Adams Arms piston system, you'll have an upper that will run cleaner, cooler, and longer than any other AR upper you own.

1st Impressions Review by 54lariat
So I bought this BLEM model, this was for my first build I have done. I own Ruger and Sig piston rifles. I like the piston systems and after lots of research AA is the way I wanted to go. I have not had a chance to fire yet but from the 1st impressions I am very happy with this choice. As far ans the Blemish all I can find is some light scratch marks on the barrel and all marks and stamping seem to be in the proper location. I might just buy a second after I get some rounds thru her. I experienced prompt shipping considering they were at SHOT when I placed the order. Less than two weeks is acceptable for me given they were at SHOT 2015. More to come (Posted on 2/4/15)
