Haven't read all these ~50 pages, so don't shoot me right away if there is already a answer told:
M16 mags work great with R85 if you just bend the metal. That's said somewhere in first 10 pages.
Is there any way to fix the gun so that plastic mags work without making any changes to all freaking 8 mags I'm gonna carry? Like adding some little plates to guns mag locking holes?
