Crossfire info from google search:
The Crossfire Mk1 is a unique weapon in that it is a 12-gauge/5.56x45mm over/under, selective fire, repeating, pump action rifle/shotgun. Designed by Crossfire and engineered by Saco Defense in the late 1990’s, the Crossfire MK1 is equipped with two barrels; the upper barrel accepts a magazine that holds four 12-gauge shells while the lower barrel will accommodate any AR-15 or M-16 style magazine. The Crossfire Mk1 actually supports two independent actions with separate, reciprocating, multi-lugged bolts, however, is fired by a single trigger. The ability to select from a rifle or shotgun round allows the user to resourcefully adjust their firepower to match each situation they encounter.
An idea ahead of it’s time?
That thing looks and sounds awesome.
I wonder how dependable the selector is?
