Spare Mag Lip for GHK Airsoft M4 GBB Magazine

"Just an update from my last review. I had to ordered more of these and I realized that have an updated version that does not work with Gen 1. G5 magazines. You'll have to chop off and sand the side nubs on top of filing the hole where the BB's come out to prevent cracking.

"These work with GHK G-5 magazines, but they are delicate. I've had two crack just from reloading so always buy more than one if you want to repair your magazines. The lip itself is great, but reloading a G5 is notoriously difficult and hard on the lip.
