The MAC 1014 12 Gauge Semi-Auto Shotgun from Military Armament Corporation is a gas piston tactical shotgun built for home defense and range work (brand part no. 21000120). It carries an 18.5-inch barrel with an adjustable ghost ring rear sight and a white blade front, so the sight picture is ready as it ships. A Picatinny rail on the receiver gives an optic a solid place to mount, and the polymer pistol grip stock adds a rubber recoil pad and an integrated sling attachment. A Benelli/Mobil pattern choke system and an included choke tube kit let you tune the pattern to the load and the job. For a shooter who wants a piston-driven 12 gauge that is set up for optics and accessories from day one, this is a straightforward place to start.

Key Specifications

• Chambering is 12 gauge, with a chamber that accepts both 2-3/4 and 3-inch shells so one gun handles light and heavy loads.
• The action is a self-regulating gas piston semi-automatic, designed to keep cycling consistent across different shell types.
• Barrel length is 18.5 inches with a chromate finish, a length that stays handy in tight spaces.
• The choke system is Benelli/Mobil pattern, so aftermarket tubes in that pattern fit when you want a different constriction.
• The included choke tube kit supplies Cylinder, Modified and Full tubes plus a wrench, giving three pattern options out of the box.
• Sights are an adjustable ghost ring rear with a white blade front, a pairing that lines up fast at defensive distances.
• A Picatinny rail on the receiver is the mounting point for a red dot or other optic.
• The stock is a polymer pistol grip design with a rubber recoil pad and an integrated sling attachment, which tames recoil and makes carrying easier.
• Overall length is 40.1 inches, a figure that tells you how it handles in tight quarters.
