A must have - GunVault AR MagVault Rifle Lock

The bright orange color helps to identify the weapon is secure, it's easy to use, and durable. It sits completly inside the mag well so no worries snagging on something, scratching the firearm, nor could it be cut off like a cable lock. It doesn't allow the upper to be separated from the lower when inserted as an extra security benefit. It's a must have. I would recommend and purchase again.
