Coming soon to the Mega Arms product line is our new monolithic tactical system (MTS-300) mid-length upper. We start with billet 7075-T6 aluminum, and machine this true monolithic part; a design which is an extension of our new billet upper. Comes complete with our newly designed barrel nut and wrench. The exciting part about this design is that it is compatible with nearly any stock barrel. Look for this design to be on display at the Las Vegas SHOT Show in January booth #2338. Also, watch for this new monolithic tactical system to be available in pistol and carbine lengths in the coming months!
