I was watching this gun for a while and picked one up from RTI a couple of months ago at a great sale price. Seems to shoot a bit high using the standard iron sights. I also haven't found a 12ga load that will run the gun on a lower gas setting than max but that is okay. It is not compatible with Vepr Mags. It wants Saiga Mags. Vepr Mags are missing the front locking lug and while they seem to fit in the magwell fine they will hang nose down when full and cause failures to feed. Get Saiga Mags -same price for SGMs.
