We put my AR Colt Combat Unit Carbine to the test with a trial run of 90 rounds, dirt and sand, and submerging it in water. The result is impressive with a firearm you can still depend on in the line of fire.

Correction: In the video it was stated the Colt CUC had a 1.6 inch barrel but in fact it has a 16.1 inch barrel.
