TriStar Arms introduces the best new option for a personal defense shotgun with the TEC 12. The TEC 12 functions as a semi-automatic and pump action in one firearm, on the same frame with the turn of a dial. This shotgun uses an inertia Rotary Bolt for a smooth action response when in semi-auto. This new gun offers a 3-inch chamber, a fixed pistol grip stock, picatinny rail, ghost ring sight, bridge front sight, tactical and swivel studs and two choke tubes. The 12 gauge TEC 12 weighs 7.2 lbs., has a 20-inch barrel length and has an MSRP of $689. All TriStar shotguns come with a five-year warranty.
