These Inbore Devices have without a doubt paid for themselves. The MEU (Marine Expeditionary Unit) Tank Platoon was only alloted 190 main gun rounds so all work up Gunnery Tank Tables conducted on this float, were conducted by utilizing the cal .50 Inbore Device.
As a Master Gunner and SNCO I will continue to use and tell others about the pro's of using the Inbore Device.
