Kiwi Milsim - Featherweight M249 Box Shim

For those that use featherweight M249's from A&K and suffer from a loose magazine catch/latch interface, use this shim to take up the gap and prevent your mags from falling out. Fits over your box mag catch. Recommend installing with a touch of instant glue to ensure retention.

(2 pack)
