Cycle of Operation

OPERATING PRINCIPLES

The Z15® is a mid-length, direct impingement rotating locking bolt system. When the round is chambered and the magazine is seated, firing begins when the trigger is pulled and the hammer falls.

The hammer will strike the back of the firing pin which strikes the back of the primer. The powder in the cartridge will ignite and force the round down the barrel. Rifling in the barrel will twist the round as it proceeds forward. When the bullet passes the gas port hole at the top of the barrel (located at the gas block), heated gas from the burnt powder will flow upward and back down the gas tube toward the bolt group.

The gas flows through the gas carrier key and forces the bolt to rotate and unlock. At the same time, the hammer is cocked by the bolt’s movement to the rear.

Once the bolt travels all the way to the rear, the spent case is ejected and another round is fed through the magazine into the chamber.

The bolt is forced forward by the compressed recoil spring. Once the bolt closes on the new round, the weapon is ready to fire once again. This process is repeated until the weapon is out of ammunition and the magazine follower pushes up on the bolt catch. Once the bolt catch is engaged, the bolt is locked to the rear.
