.....they have found another way to market slug guns and barrels to current owners. Read the information under the new Model 870 Super Slug.
Model 870 Super Slug
A tricked-out version of Remington’s awesome slug gun, the 12- or 20-gauge Super Slug features a new barrel with
Ultragon rifling that delivers rifle-like accuracy at 100 yards and beyond. This is the real deal — the gun delivers 1- to 2-inch bench groups at 100 yards with regularity and is an able companion to Remington’s hot new Premier AccuTip Bonded Sabot (which, by the way, will be offered in a 20-gauge version next year as well). The 870 Super Slug has a ShurShot synthetic stock (camo or black) with rubber overmolded pump panels, and is available with a 25 ½-inch fluted and extra-heavy barrel (with scope mount) in the 12-gauge version or an 18 ½-inch cantilever barrel in the 20-gauge model (2 ¾- or 3-inch). If you shoot the 260-grain, .45-caliber AccuTip slug in 20 gauge, you probably will decide that it provides all the firepower needed for whitetails. The 12-gauge will sell for about $700, the 20 for about $500.
