The much anticipated MEGA Arms MATEN (.308) Tubular Monolithic upper receiver is finally here!  Many MATEN owners have been asking for a lightweight Tubular option to their already extremely popular Monolithic Quadrail upper and of course MEGA listened.  The new 12″ lightweight Tubular design features a true monolithic 12 o’clock 1913 Picatinny rail while the remaining area has been machined to a smooth round surface.  It’s also modular in the fact that you can add small 1913 rail sections the the handguard for mounting accessories if needed.  

I personally own a MEGA Arms lower receiver and can vouch for the quality and craftsmanship of these pieces.  If you are looking to build a .308 AR based rifle the MATEN platform is the way to go.  Check out the rest of the details and pics below.
