This unique magazine provides both a clear window on the side showing the number of rounds remaining in the magazine and a full magazine indicator button on the bottom. The clear window on the magazine side allows the user to easily view the number of rounds remaining, corresponding to the numbers stamped into the body. In addition a white full magazine indicator on the bottom pops out of the magazine base, providing a tactile indicator of a fully loaded magazine during low light or night operations. The full mag indicator can be preset to pop out at either 29 or 30 rounds by adding or removing the follower extension.
Note: Shipping restrictions are active in AK, CA, CO, CT, HI, IL, MA, MD, NJ, and NY for magazines with 16 or more rounds.
