I recently saw a video where a guy had a 12 gauge in an ar15 platform. He had it loaded with buck shot and was hog hunting. The hogs took off running and he proceded to shoot 5 or 6 pigs on the run before they got out of range. With a 10 round clip full of 3in oo buckshot you can put a whole lot of lead downrange. I began looking in to mag fed semi auto shotguns and found the akdal mka 1919. A 12g in a platform based on the ar15. I am already very familiar with the ar15 platform and I am very interrested in this shotgun. Does anyone who has ever shot one of these have any pros or cons on this gun. I was also wandering if the ipper from this shotgun will fit on a standard ar15 or ar10 lower?
