The Ruger PC-4 Carbine in .40 cal. It functions similar to the 10-22 rifle. I got mine (w/ the factory ghost ring sights, as shown) in 2005. Sadly, they were discontinued in 2006. It is unfortunate because this is a solid carbine with minimal recoil, which shares mags with any Ruger P-series .40 cal. pistol (such as the P-91 and P-94). I have mine sighted in at 100 yards and recently took a wild pig with it (without optics) at 120 yards.. dropped it with one shot. If you see one, get it.
