Valkyrie Armament, a gun modding company, brings us the Belt Fed AR15. The VA Belt-Fed AR utilizes an ammo box to feed the belted ammo but making the switch to magazine-fed operation is quick and easy. Just push out the rear takedown pin, hit the mag release button, pull the belt-feed tray out the top and close the rifle back up by pushing the rear takedown pin back in. Bam. Now you can run mag-fed, mowing down zombies. Just grab some Zombie Max Ammo and you’ll be ready to go.
