KSC MK23 SOCOM magazine lip
 

well, its a bit of a long shot, but Ive searched quite a bit and havent really found anything
I recently picked up a 2005 version socom with a broken magazine lip

and there are magazines for the 2k5 version and the previous versions

anyone know if the magazine lips for the earlier versions are interchangable with the 2k5 version?
I can only find the lips for the early versions and if they are interchangable...its a lot cheaper than buying a replacement mag
