Styrling Auto Twelve

With the prevalence of more high-end, semi-automatic shotguns distributed to the military, Styrling decided to appeal to the “every-day man” and develop a relatively cheap, but robust, pump action shotgun. But then there were those who wanted the secure feeling that comes with a selective-fire shotgun, with the capacity (and price) of most assault rifles. Magazines produced for the Thunder come in either a 5 round box magazine, or a 25 round helical magazine that carries 12 gauge shells. Chambered for the standard 12 Gauge shell that has become commonplace in every gun store, the shooter does not need to buy special Styrling-manufactured shells such as the Styrling .45, however, coupons on components and gear are available in each ammunition box.

Firing Mechanism

Gas Operated

In gas-operation, a portion of high-pressure gas from the cartridge being fired is used to power a mechanism to extract the spent case and chamber a new cartridge. Energy from the gas is harnessed through either a port in the barrel or trap at the muzzle. This high-pressure gas impinges on a surface such as a piston head to provide motion for unlocking of the action, extraction of the spent case, ejection, cocking of the hammer or striker, chambering of a fresh cartridge, and locking of the action.
