staining plastic magazines

Not sure if they work in the 15-22. I use it in an ar with a cmmg style bolt carrier

Thanks

Technically, they are for a dedicated CMMG upper or a conversion. However, they should work in the 15-22. I have a dedicated CMMG upper that I use on a "regular" M&P 15 lower. These mags work very well. Of course the 15-22 has the polymer receivers but I think the dimensions are the same.
