Willing to trade only for a Tokyo Marui SPAS 12. Working or non-working, with or without stock. G&P Airsoft M4 Rail System GBB Gas Blowback Navy SEAL Skull Frog. Unsure of what kind, but it has a replica MK18 rail system (it’s not Madbull). Condition is "For parts or not working". A G&P M4 GBB. Full metal and a great Airsoft repair piece. Rifle does NOT WORK, but I believe this is because of the magazine and trigger spring being broken. Beyond that, this gun has EVERYTHING minus a crane stock. You should be able to fix this gun for under $50. Issues that I know of: 1: Safety will not engage when discharged. 2: Magazine will not fire. 3: Trigger spring literally disintegrated in my hand (no trigger spring). Everything else is in fantastic cosmetic condition. Very little wear. Asking $325 semi-firm, open to negotiation. I was not the previous owner. I can not guarantee anything with this gun. This listing is fully accurate to my knowledge. Thank you for looking!
