Kit A (AR-15) 4 Pack

Availability: In stock

Our injection molded nylon tips are super durable, reinforced by stainless steel mounting hardware, and easy to install. The unique (patent pending) shape of the UBBT tip makes it compatible with ALL major brands of AR-15 magazine locking devices.

Great product.Review by Eddie C
Unfortunately, I live in Commiefornia where that lame ass Bullet Button is required on all AR-15 rifles. This product helps me change magazines so much faster than trying to find a
tool to remove the magazine and it's legal. It's easy to install with just a drill and screwdriver.
This product will keep you out of trouble with the law and it's very cheap to purchase.
I highly recommend it. Eddie C. (Posted on 4/28/2016)
