Bumpers for pump mags

[BLachance75]

Did someone used to sell bumpers cut to fit inside the wave spring on a pump mag. I thought I remember someone selling them but I can’t recall who it was.

most people cut down blue bumpers to fit in the spring.

Just cut a blue bumper, it'll last longer, and be easier than looking for one

Is the purpose to keep the spring centered during assembly or is it for its original purpose?

Agd did make pump bumpers, they were black and smaller. That being said waaaaay easier to cut a standard one
