BCL MRX mags in Renegade
As title suggests:
I bought some mags, but encountering the following:
- bolt will not go forward
- extremely tight in mag well
After comparing to pmags, it seems the spine of the MRX mag is higher.
Is it legal to mod these mags? Anyone have experience making this work?
I just wanna go pew pew with a 20 rounder lol

"Overcapacity" magazines are prohibited devices, and modifying a magazine is considered to be manufacturing; therefor modifying an MRX magazine to fit a rifle is manufacturing a prohibited device. On the other hand, manufacturing a non-restricted firearm for personal use doesn't require any special license; so you can modify an NR semi-auto rifle to feed from MRX magazines because the magazines are still considered to be intended for a manual action rifle.
