Old project I abandoned, but still has plenty ofvalue. A&K M4 S System that I put into a gorgeous Zeke metal body. Zeke was the Lexus of metal bodies at the time. Beautiful finish and full trades. Better pistol grip, sling loop, metal flash hider, ambidextrous mag release, body screws instead of push pins, and a removable butt pad also installed. There are internal upgrades, but honestly I don't remember what they are. Gun will meet t cycle so may need an AOE adjustment. Motor will turn when out of the gun. This would be a great gun to finish or put in an HPA system--cosmetically very, very nice. Free shipping to lower 48. Trading only for GBB items, but would prefer an outright sale.
