I have a Supernova Tactical with pistol grip (I think they call it 'the suregrip' or something, but we all know what I'm talking about). I am interested in a sling mount for the rear, and have noticed KZ (Kley Zion) makes a few different models, but they list them as working for the M1/M3 or sometimes the M1/M4 - the stocks look the same to me, but I wonder if someone can definitively say if they will work on my Supernova. They are designed to go between the receiver and the stock - take off the stock (loosening it is required for disassembly anyway) and insert the piece. I imainge it owuld work, but would just as soon avoid a waste of time and money if I buy one and for some reason the angle is a bit different, or the bolt is a different size, or they are incopatible for whatever reason. Thanks in advance for replies.
