Wei-ETech M4A1 Carbine GBB Full Metal V3

Received as a gift about a year ago, tested it once indoors for a few minutes, never used on a field. Basically like new.
Full metal body, AWSS Open-Bolt GBB system (Version 3), adjustable stock (4 positions), 30-round magazine included. Up to 1.2J, runs on Green Gas.
Note: V3 uses proprietary magazines — only Wei-ETech AWSS V3-compatible mags will work.
