Mega Arms – Megalithic AR-15 Upper


The Mega Arms Megalithic AR-15 upper is machined from billet 7075-T6 aluminum, giving it a 70% increase in strength over 6061 aluminum. It is black hard anodized with a surface hardness of 60 Rockwell. Its material and construction allows it to weigh only 22.3 oz.


The Megalithic upper features a fore end with keymod at the 3, 6, and 9 o’clock positions, and a flat top Picatinny rail. An integrated leveling system placed between the upper receiver and handguard rails can be configured for both left and right handed shooters.


Comes standard with a dust cover door, forward assist, a keymod compatible Picatinny rail segment, barrel nut, and barrel nut wrench. Available only in rifle length at this time.

    That looks so nice and clean. I have one of their older style monolithic uppers, Kind of wish this style was around back when I bought it.
