compatibility question
 

well at the local JOC game and the first time i fielded my new CA-SG1 my stock broke :(, but i was going to replace the stock with a A4 stock anyways so heres my problem i cant find a CA A4 stock only the TM.

so can i put a TM G3A4 stock on the CA-SG1 with no mods or will i need to get out a file?
