MP22 mags are $$ enough without a magpul license lol
The PMAGs sold with the M&P15 (5.56) have the S&W logo on them--still Magpul......that would be cool for the 15-22.
Not wanting to rain on your parade, but what would you do about the load assist button?
I would like to see something like that built as a 10 round mag.
You may be right, on a 25 round mag it is nice to have for getting the last few rounds in easier.I think the load assist button is what gets most people into trouble with staggering issues. Wouldn't be so bad if it was gone.
