The T-14 shotgun was developed by Turkish company Safir Arms. It is broadly based on the famous Ar-15 / M16 rifle, but has several patented features necessary for reliable functioning with shotgun-type ammunition. At the present time it is offered in only one caliber, .410x65 (also known as 36 gauge, 2 /12 inch chamber). With .410 caliber bullet weighting 7.5 gram (116 grains) manufacturer claims muzzle velocity in 700 m/s (2,290 fps) range, providing muzzle energy of about 1,800 Joules (1,320 ft-lbs). The T-14 shotgun is semi-automatic only and is available in different barrel lengths to make it legal for civilian use in various countries that permit its citizens to own shotguns.
