Anyone have any experience with the mossberg scope/barrel combo? All that I know is that it's a 24 inch rifled 12 gauge barrel with a scope mounted and boresighted on it. I am wondering if it'll be worth it to buy. Currently I have a Maverick 88 18.5 inch smoothbore with a front bead. I am ok shooting foster type slugs out to 75 yards, but I am wondering if this combo would improve my range with slugs. Any info would be appreciated. Thanks!
