I just got a new G36. I cleaned the gun and the First trip to the range I fired 50 rounds of Federal ammo, the ejected cases would go in all directions and the gun would jam about every 2 or 3 mags. I cleaned the gun ( used Ballistol) and the second trip to the range I fired 70 rounds of Federal and Winchester ammo and the gun still jams every 2 or 3 mags. Should I send the gun back to Glock for repair or is there a simple fix? Thanks Wanna kill these ads? We can help!
