Firing Some Awesome and Interesting MAC Uppers!

Consider this a “1,000 Sub Special!“ Thank you all for watching my videos! Firearms used: Ingram M10 (or MAC 10) equipped with a Lage MAX 10/31 9mm upper receiver, and a MAX 10/15 upper receiver. It’s worth noting these upper receivers are identical in function to the MAX 11/31 and MAX 11/15, it’s just the lowers they interface with that is different. Thanks for watching!
