Forged 6061-T6 upper/lower receiver Viper Tech BCM MCMR GBBR.
M-LOK handguards, receiver pins, buffer tubes and buffers, buffer springs, gas blocks, and pistol grips are original parts from Bravo Company and V Seven.
I installed Aimpoint AB's T2 Red Dot Sight(with Scalarworks LEAP) and Vortex's Micro 3X Magnifier on the upper receiver rail.
