Meet the SKO-Bull, a 12 gauge semi-auto bull pup shotgun from the makers of the DP-12. This prototype takes both 2 3/4″ and 3″ shells in either standard or bull pup configurations. The weapon features all the familiarity of an AR-15 with the compact versatility provided by a bull-pup orientation. Expect to see an MSRP around $1,299 once these hit the market.
