I have a late 24v, .223/12G, 3" w/screw in chokes, uses Mossberg chokes, and the syn. stock. This thing shoots like a house afire, the rifle has the 9 twist rate and will shoot anything from 45 grains to 70 grains, and shoots as good as my HV bolt action .223. With a full choke the shotgun shoots a killer pattern out to 40 yds, and loves #5 and 6 shot. I use the open sights, marvbles with a white bead front that came on it, and use it as one of my favorit yote calling setups here in KY!
