Slr mag prime and perun mosfet

Hi all
Goin for my first mosfet install on a slr and got eyes on the perun. Wondering if the slr mag prime will still work if I solder the wires accordingly to the mosfet?

Hey bud, I know if you want to run the prime function with a Perun you need a one way diode on the positive wire to the magazine.
Hope that helps


thanks mate, sounds like im ditching the mag prime switch then haha

I ditched it purely because working on the box with it installed requires more thumbs and tolerance for fkry than I have.

I don’t miss it

A not on the perun: DO NOT TOUCH the sensors. They are super sensitive to grease and such and will annoy the fk out of you if the are dirty

As far as fitment of the perun. Is it just a straight drop in or do I need to file some parts of the gearbox?

I’ve done two and not needed to make any changes to either box
