A&K M249 (non Working) with working Box Mag Used A&K M249 that has seen better days. If you are good at working on these things this is the gun for you. Here are the issues that it has: MAJOR: Grinding noise from gear box and the piston will not cycle. I just put a new 18:1 gear set (SHS) in it because the last set broke. My guess is the piston is worn out and not engaging. Last person before me rewired it to the rear with heavy duty wire. Did work for about a year of once a month playing. Has feed issues. Minor: The issue is that when the outer barrel assembly is fully inserted it pushes the HopUp back against the gearbox. This causes the HopUp to come out of the keyed slot which then allows the hop up to twist a bit making feeding an issue. Minor: The rear stock is on with 3 pins. The rear site is missing. The pin to hold the top closed is missing (Velcro works well). Part of the front gas compensator is missing (cosmetic issue). The bipod is currently off of it but is included. When it shot, it shot around 375FPS if I remember correctly. Last Person painted it. ApyPal+ Shipping or Local Meet up in the Dayton, Columbus, Cincinnati region
