Product Info for Aero Precision M5E1 18in .308 Winchester Complete Upper Receiver with Flash Hider
Here is one of the best .308 rifle upper assemblies you can buy. The Aero Precision AR 308 Upper includes an M4 length gas block, 18" rifle length stainless steel barrel, and an Gen 2 enhanced handguard. The upper itself is a one-piece, free-float design crafted to be one of the strongest, lightweight, and long-lasting assemblies on the market. And the handguard platform is precision machined from 6061-T6 aluminum, and the top Picatinny rail is scalloped to help you mount even more accessories. The upper also features M4 feedramps and a port door, while the takedown pin holes are .2795. This upper receiver is an M5E1 version, which means it is compatible with both receiver extensions. The upper also has a .750 gas block journal, a rifle length gas system, and a forward assist and port door drilled into the barrel. That means you can use standard AR .308 components with this build. For a one-piece, free-floating upper receiver that is built to last and perform to the highest standards, install the Aero Precision AR M5E1 Upper Assembly.image
