RPB SM10 Mag Wobble

[UnluckyBastard13]

Just wondering what amount of mag wobble is expected with these guns? I assume that some amount of wobble is to be expected with Macs, knowing their tolerances aren’t anything crazy. Mine came with 4 grease gun mags that have been converted and they wobble more than anything I’ve ever seen before. Im honestly surprised they stay in the gun and snap in. Is there anything that can be done about this?

The first thing that I would do is call Sam at Practical Solutions. He has specialized in repair of the Mac style family of RRs for the last 20 years. Have you tried to fire the gun? I imagine that you could shim the magazines. But I am not sure which way the magazine should be moved.

I had a couple of wobbly gg mac mags. I just cut a small piece of bicycle innertube and slid it over the mag above the mag stop.
It stops the slop and hasnt interfered with performance.

If the gun runs don’t worry about it. Try it sideways…gangsta style…with the ammo weight off the gun.
