I thought about just PM'ing you, but then thought others might have this gun, too, and need to read this. The Smith & Wesson (
S&W)
M&P15-22 has been recalled. Apparently some of them can 'slam-fire' and go full-auto. Yee-haw! But probably not very safe. Read up on it here:

Excerpt: "
STOP USING YOUR M&P15-22 UNTIL IT HAS BEEN INSPECTED AND YOUR BOLT REPLACED (IF NECESSARY).
Smith & Wesson has identified two M&P15-22 firearms from recent production on which the breech face counter bore depth was not within manufacturing specification. In those firearms, the lack of depth may allow the bolt, upon closing, to crush the rim of the case, causing the round to fire, cycling the bolt, and potentially resulting in multiple discharges without depressing the trigger."
