Just got this email from Midway:
We just received a shipment of the following product:
ProMag Magazine Ruger Mini-14 223 Remington 10-Round Steel Nickel Plated
Supplies may be limited and are first-come, first-served so don't wait until they are gone...
I have 2 brand new in box promag m&p 15-22 10 round magazines for sale. $40 each local pick up. If no interest here I will throw them to the ebay/ armslist wolves. If you would really like a picture I can take 1 I am just being lazy.
Took my son out today to shoot our new M&P15-22. I have two S&W mags and two ProMags. The S&W work fine, but both Promags leave the last round in the magazine. Bolt gets held open. Only way to get it to close is to remove the mag. A quick visual inspection of the empty mags side by side...
