PSA Firearms had the Panzer AK12 on sale for $399, so I thought I'd give it a trial, very well built and just about all parts DO interchange with the Saiga, my old Saiga 12 is about 25 plus years old, but still handles just about anything, but it's nice to have a back up at a lot less cost. Mags, Drums swap out with no problem, the major difference is the Panzer comes with several chokes and the barrel is not threaded like the Saiga, but it's rock solid. So far no regrets
