read a post on ar15.com about an ar pistol in 9mm. i have a bushmaster ar pistol in 5.56 and was wondering if any body has a 9mm ar pistol or where i can do some more investigating on changing mine over....daryll
Swapping your pistol over to 9mm you wont be saving much except the lower.....But you would need
9mm upper
9mm bolt
mag block
9mm buffer
9mm mags
different hammer depending on what bolt you use
