Are You trying to sell the mr 920 also and what’s the issue?
I have two and one is already back in Plano,tx. The one I sent back had 7 light primer strikes. The ejector was walking out of the trigger housing. The hood of the barrel was chipping,and the trigger was heavy and gritty.
The one I have now has issues with the mag release getting chewed up and the trigger isn't as good as it was before. Shadow systems recommends to use pmags with their guns,so I did. It still chewed it up. I switched it out with an OEM release and only after 200 rounds,it's getting chewed up again.
I'm going to sell them once I get them fixed. I don't feel right selling them right now. When I do sell them,I'm gonna tell them how much these things suck. I had two mr918s before and they had issues as well.
