Hi to everyone, I've been reading this forum for weeks and you guys are a wealth of info and guidance ! Last week I purchased an M&P AR 15-22 for my wife from a private dealer friend of mine. We took it to the range and needless to say she loves her little AR and I'm just amazed with it. Taking your advice for ammo it went thru American Eagle, Winchester Super X, Federal Bulk, CCI mini mags without a problem. Brett248Vista your videos are great, thank you ! Now the question I have about the Slide Fire Stock, their website refers to a letter from ATF about their stock, for those of you that have these stocks what's this letter all about, is it an approval or what ? Great forum !!
