Built this one up on a lower from a pre-ban Colt Sporter Target.
This is a lightweight barrel upper receiver, foregrip and rail from M&A Parts.
Stock and ARMS #40 from Adrenaline Arms.
EOTech 512 and sling from Viking Tactics.
TangoDown BattleGrip from Buffer Technologies.
Flashlight is a SureFire Nitrolon G2 on a 1” scope ring.
I’ll shoot it very little, so I’m not really concerned about the fragility of the light.
