About
What it is, and why it matters
The Derya MAX is a magazine-fed, gas-operated semi-automatic 12-gauge competition shotgun launched in August 2026 and built at Derya's Jacksonville, Florida plant. A curved self-cleaning gas piston cycles everything from 7/8-ounce target loads to 3-inch magnums, and the gun carries an adjustable stock with 12- to 15-inch length of pull, an AR-compatible pistol grip, a threaded smoothbore barrel, flip-up irons and a full-length Picatinny rail. It weighs about 9.5 pounds.
Derya built its reputation in Turkey supplying budget shotguns under other companies' names; the MAX is the first gun the firm has built on American soil under its own.
Aimed at USPSA, IPSC and 3-Gun competitors. Ships with Mobil chokes in Full, Modified and Improved Cylinder plus two polymer magazines.

Trajectory
What the round does downrange

No load solved for this record yetThe flight path is computed from a cartridge and a bullet. This record has no ammunition filed against its chambering, so there is nothing to solve.
