CA25 Disassemble
 

Ok i'm wondering how can i disassemble the RIS handguard? I need to install the Rail Panels and the only way to do it w/o scratching the paint job is to take the whole RIS handguard apart.

I'm thinking: Take the gas block off and the whole thing unscrews (free floating barrel).

Also, how do i know to assemble the RIS hand guard the proper way? (so the rails faces up, down, left right).

Thx :)
