FRAG-12

The FRAG-12 is a specialized 12-gauge shotgun shell which contains a small amount of high explosive to breach intermediate barriers, defeat light armored vehicles, and disrupt IEDs.[1] The shell was designed by the Special Cartridge Company in London, England. Later its patent extended to Olympic Technologies Ltd in Gibraltar.[2]

The shell uses a 50 mm (2.0 in) long metal body filled with 3.4 g (0.12 oz) of composition A5. Four folding fins spring out after leaving the muzzle. The shell arms at 3 metres (9.8 ft) and explodes on impact by MIL SPEC 1316 fuze. It has a maximum range of 200 metres (660 ft).[3]

A company called Combined Systems, Inc. sells FRAG-12 under the name FRAG12HE.[4][5] The rounds have low popularity due to relative high cost to performance ratio, limited application, and being limited to military only purchase. Sales seem to be limited because of the wide array of other available rounds for military users in more suitable calibers such as 20×30mmB K-11, 20×42mmB PAW 20, 25×40mmB XM25, 25×59mmB LW25, 30×29mmB VOG-17, 35mm CL DFS10 VOG-17, 35×32mmSR DF87, 40mm CL VOG-25M, 40×46mmSR LV, 40×51mmSR MV, 40×53mmSR HV, and 40mm CL Balkan[6][7]calibers used by the M203, M320, Milkor MGL, AG-C/EGLM, GP-25, and similar dedicated grenade launcher devices. The round was widely advertised with the Atchisson AA-12 assault shotgun.
