Tokarev USA 21000423 T300M A1 Kit 12 Gauge Semi-Auto 3" 5+1 18.50" Electroless Nickel Ventilated Heat Shield Barrel, Electroless Nickel Receiver w/Picatinny Rail, Fixed Black Polymer Stock

The Tokarev USA T300M A1 is a 12-gauge semi-auto shotgun purpose-built for home defense, tactical work, and serious range time. Chambered for both 2¾" and 3" shells with a 5+1 capacity, this gas-piston-operated semi-auto delivers the reliability you need when it matters. The 18.5" barrel wears an electroless nickel finish and ventilated heat shield to stay cool under sustained fire, while the nickel-finished receiver is topped with a Picatinny rail for mounting optics, lights, or other modern accessories. It's a straightforward, no-nonsense platform that works as well for home security as it does on the range.

Handling is instinctive thanks to the fixed black polymer stock and forearm—durable, weather-resistant, and built to take hard use. The shotgun ships with adjustable ghost-ring rear sights and a fiber-optic front sight, giving you a solid sight picture out of the box. The Tokarev T300M accepts Benelli®/Mobil-threaded chokes, and the package includes a choke tube kit (cylinder, modified, and full, plus wrench) to dial in your shot pattern for different tasks. At 6.77 lbs unloaded and 38" overall, it's compact enough for tight quarters without feeling undergunned.

This is a working shotgun for people who understand that simplicity and reliability trump bells and whistles. The dual-stage gas piston system is designed to run clean and consistent, and the proven platform is already out there in field use. If you want a 12-gauge semi-auto that handles like a rifle, customizes easily, and doesn't ask for excuses, the Tokarev T300M A1 is worth a close look.

Frequently Asked Questions

What chokes are included with the T300M A1?

The shotgun ships with a choke tube kit containing three tubes—cylinder, modified, and full—plus a wrench for installation. The barrel is threaded for Benelli®/Mobil-pattern chokes, so you can add other options as your needs change.

Can I mount an optic or light on this shotgun?

Yes. The electroless nickel receiver is equipped with a Picatinny rail, which accepts standard optic rings, red-dot sights, shotgun scopes, light mounts, and other modern accessories.

What ammunition does it chamber?

The T300M A1 is chambered for both 2¾" and 3" 12-gauge shells, so it runs standard and magnum ammunition. Capacity is 5+1 (five in the tube, one in the chamber).

Is the barrel ventilated, and why?

Yes, the 18.5" barrel includes a ventilated heat shield. This design helps dissipate heat during extended shooting sessions and keeps your hand clear of a hot barrel when you need access to the forearm.
