Hi Guys -
I just bought my first SG, a supernova tactical. I put a nordic components magazine extension on it (+2) and for the life of me cannot get it to work. I used the spring that came with the kit, I cut it down some per the instructions. I cannot get the +2 shells into the magazine. It will load four, just fine, number 5 will go in, but the little catch that keeps the shells in the tube won't engage. It feels like everything is bottomed out. There is NO way I could get a 2nd additional shell in the mag.
I went and put the stock spring in, thinking maybe the spring that came with the kit was still to long and rather than start blindly cutting, thought I would try the stock spring first. Made no different. I still can only get four rounds in the magazine.
Does anyone know what might be going on? Thanks all!
