Our friends at Potomac Armory have cut the standard FBI 11.5" barrel down to 10.3," and inspected, and where needed, re-drilled the gas port to be the correct 0.070" port for the ultra-short gas system. They have also pre-dimpled at 180 degrees from the gas port, for proper alignment of a low-profile gas block.

Shooters and law enforcement typically choose the 11.5" barrel, as it has better overall performance, especially in the heavy (SOCOM) profile.
