5.56 NATO 70 gr GMX® TAP® BARRIER™

Item #81265

TAP® Barrier™ turns cover into concealment. The 5.56 NATO 70 gr. GMX® Barrier™ round is a fantastic option for tactical situations that require deep penetration and terminal performance after contact with any FBI established urban barriers. The 70 gr. GMX® is a monolithic solid bullet constructed entirely from a premium copper alloy that will deliver high weight retention and deep penetration. This bullet is well suited for guns with faster twist rates and is extremely reliable for patrol carbine use or any other situation that may involve vehicles or barricades.

NOTE: NOT for use in 223 REM chambered guns.
