WILL TRADE FOR A MK46 OR M249, or MK18/Block 2. Honestly I'll probably trade for any M4 that doesn't look stupid and I can easily build into a Mk18. Looking for 215 OBO. Wired to deans, internally has an upgraded piston, piston head, Teflon tape on cylinder head to improve airseal, m100 spring (I believe). Externally comes with the Magpul forgrip and 2 moe rails. Battery included but no charger. Previously tan, now black, used in 5 games. Buyer pays shipping. Willing to meet at most NC fields if you don't want to ship.
