BCL MRX mags in Renegade

Post image

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

I did yes

You need to shave down the spine of the mag or remove the last round bolt hold open in the gun!

Shoot me a message I can send you pictures
