It is not a semi-auto, but is a pump...Remington 760 ....(must buy used as they are out of production). More dependable than the 7600 which is a semi-auto. A 760 is the twin (or first cousin) to a Remington 870 pump shotgun. Available in most rifle calibers, the 760 can sometimes be found in "carbine" length which sports a 18" barrel. I use one as my hog gun, 30-06 caliber carbine, iron sights and a green laser. Get one made in the sixties and they are fine guns. $300 to $450 on the auction sites.
