We just picked up a M2 propane firing weapon for one door mount of the UH-1B Gunship my Army Aviation Heritage Foundation chapter is completing restoration of. It looks authentic. I thought it was a real de-miled weapon. Barrel even has rifling. But when I opened the top cover I then noticed it was missing parts and had a spark pug screwed into the chamber. The other door will have a bungee mount M60. The M60 is an awesome all metal replica air soft gun, just $440. It even has real (not live) ammo in the exposed belt. Will send photos when we have it all mounted up. M-40 Grenade launcher is already installed. Rocket pods and guns to go this weekend. Will debut in a Veteran's Day parade on Nov 12th and be loaned to the Commemorative Air Force Museum at Air Base Arizona, Mesa AZ.
