Brownells USA Instant recognition of rifle status 20/07/2018

You can open your safe or walk into the Arms Room and immediately tell those AR-15/16 status. Very visible in safe or on wall rack and it does not mar the rifle or AR pistol in any way. To have it drop immediatley to the floor a quick tug on the charging handle will accomplish that and you can stick in a loaded magazine and be ready to go. For patrol officers you can carry your AR in the locking rack in your vehicle and know that is is clear. Recommend highly!
