To confirm its belief that it had built a superior firearm, Adcor Defense tasked H.P. White Laboratory to performance test the B.E.A.R.™

H.P. White Laboratory is known as the leading small arms and ammunition research, development and testing laboratory in the U.S. It numbers among its clients, many branches of the U.S. military, the National Rifle Association (NRA), several firearms manufacturers and ammunition companies as well as global firms such as Caterpillar, GE Plastics, Chrysler Corporation, Goodyear Aerospace, Monsanto Chemical Co. and others.

The testing was done in conformance with portions of the First Article Test Matrix, Carbine, 5.56mm, M4 type derived from MIL-C-71186 (AR).


  • In the function and casualty testing (6,000 rounds): Zero failures or stoppages.
