Anyone know if M&P15-22 mags with "load assist button" will work in M&P15 Sport with CMMG ARConversion kit & Bolt Hold Open Adapter installed?
I'm thinking "no"... but would like to verify, since the S&W mag (SKU 404850000 @ $20.04) is inexpensive & has got to be somewhat easy on loading 25 rounds.
