Lehigh Defense


Lehigh Defense is an American ammunition manufacturer, located in Quakertown, Pennsylvania. Lehigh Defense is a global leader in bullet technology. They currently offer over 200 unique solid copper bullets, and hold 12 patents on bullet design.
Lehigh's most notable bullet technology is the Maximum Expansion, a.308 caliber, 201 grain expanding subsonic rifle bullet which is used by several Special Operations Forces. Lehigh has produced over 6 million ME bullets for US and allied militaries. Additionally, Lehigh Defense patented Fluid Transfer Monolithic technology. On impact with a soft target the "flutes" on the bullet ogive channel tissue and fluid radially from the bullet's path causing wounding similar to hollow-point bullets. The main benefit of an FTM bullet is that it penetrates intermediate barriers significantly better than a lead core bullet.
Aside from solid copper bullets, Lehigh Defense is a leading manufacturer of Armor Piercing and Reactive Ammunition currently in service with Special Operations Forces around the world.
Lehigh Defense acquired SSK Industries in 2019, and has re-branded it SSK Firearms.
