Lehigh Defense is driven by a desire to transform. Throughout our 20+ year history, we've designed, tested, redesigned, and perfected many new firearm and ammunition technologies, all in the name of advancing the industry.

We started out manufacturing Swiss CNC machine Match Solid Bullets for use in competition shooting. Starting with the outdated products of the day, we questioned how to push the limits of the technology and spent months in the shop working through previously uncharted territory. Our research and testing ultimately led to the development of a world record-setting high-performance bullet that delivers the highest possible reliability.

Not content to rest on our success, we started to look into the terminal performance of hunting ammunition. Convinced we could improve upon a neglected technology, we created the industry's first Controlled Fracturing Bullet for the Muzzleloader industry. Originally developed exclusively for Knight Rifles, we have continued to work on and perfect our achievement and now offer a complete line of Controlled Fracturing ammunition.

Next, we decided to work on producing a Subsonic bullet that would match or improve upon the terminal performance of a high-velocity bullet. Today our Subsonic bullets deliver unparalleled terminal results.

As our reputation has grown, Lehigh has continued to investigate and improve upon our most revolutionary ammunition. Building on the predictability of our Controlled Fracturing Technology, we now produce personal defense ammunition with exceptional terminal and barrier performance. As a result, this revolutionary projectile has earned a reputation for outstanding bystander safety with law enforcement officials and military personnel.

We now offer our customers 12 Bullet Technologies:
