Tokyo Marui Recoil Scar in need of a repair and upgrade

Tokyo Marui recoil Scar arrives with me as it it poorly and needs a fix. Turns out this one was poor trigger contacts and a broken bolt stop. A few upgrades along the way to make this perform better than before. Getting good FPS and rate of fire. This is now ready again for airsoft battles and skirmishes. Opening and maintenance of a TM NGRS gearbox to get it to run smoothly.
