I just recieved my new GMR-15 and it is a fantastic gun. I ran my first USPSA match with it today and ran into a problem that I am not sure how to fix. Thought others with this gun might have had the same problem. There is an empty hole in the lower as you will see in the attached pictures. I cannot see that it serves any purpose other than to possibly lighten the lower? At any rate I had a magazine miss feed and the bullet dropped into this hole and took quite a bit of work to get it out. Forget this match for sure.
Any ideas of how I could fill in this hole without causing other problems? My State USPSA match is in two weeks, so I don't have time to ship the rifle back to JP even if they have a remedy, before this match.
Any help would be appreciated!
TIA
