KJ Works B9 Series GBB Magazine Catch

Had a little mishap when taking your B9 GBB apart? KJW have just the thing. The B9 series GBB magazine catch is an original replacement part, and fits both the KJ Works B9 GBB series and the LS B9 GBB series. The set includes the magazine release and its spring. Though it is designed by KJW for their B9 GBB series this mag catch may be compatible with other B9 GBBs but we aren't able to test this so please consider carefully before buying.
