The followers in the PRI 6.8SPC magazines leave something to be desired. I am grateful PRI ponied up to build 6.8SPC magazine bodies, and the majority of my 6.8SPC mags work fine to the extent I've tested them, which isn't much still being in the load development phase.
I had one 15 round magazine in which the follower kept hanging up in the last inch of upward travel. Upon disassembly, it became clear that the follower - made of thin pliable sheet metal - was bent and had burrs, so I set out to see if I could modify a Magpul follower to fit.

I have not had a chance to test-fire yet, but the magazine loaded to 15 rounds (the proper capacity for this mag) with no obvious problems, and the rounds fed seemingly OK.

BTW- Spring is a 30 round spring cut to 13 coils.
