SayUncle has been musing on the fun possibilities of a 9mm AR-15 of late.
I just thought he should know that the pile of DPMS and Rock River fire control bits that got stuffed into a Mega lower and push-pinned to a *cough* Double Star, but don't tell anybody fergawdssake, 9mm upper just the other night got taken out on the range today, whereupon they chewed through boxes of Speer Lawman 9mm like Rosie O'Donnell through a pint of Ben & Jerry's Rainforest Crunch, just as fast as I could pull the trigger.
Cheap-o, reliable, indoors 9mm AR blasting. Yum.
Think I should spring to get it SBR'ed?
