These Tromix built AR-15 458 SOCOM Economy uppers  include the exact same new  Premier Grade Tromix BCG’s and 10.5″ Lightweight Barrels just like the Tromix standard lineup of custom uppers, however, the charging handles, 10″ hand guards, and upper receivers are made from less expensive 6061 aluminum instead of 7075.  Gas blocks are steel, .750″ diameter, solid, non-skeletonized.  Barrels are 1:14 twist 4150 steel, pistol length gas system, 5/8-24 muzzle thread, A2 Birdcage Flash Hider, and externally coated with 2400 series Bake-On KG GunKote.  All of these uppers are pre-assembled so no optional or alternate parts can be spec’d out.   These uppers are test fired prior to shipping.  Some parts may have minor blemishes.
