Homemade MAC-10?
Updated: January 9th, 2013
I founded TFB in 2007 and over 10 years worked tirelessly, with the help of my team, to build it up into the largest gun blog online. I retired as Editor in Chief in 2017. During my decade at TFB I was fortunate to work with the most amazing talented writers and genuinely good people!

to build a barrel? no biggee! all yous gotta do is know how many inches per twist ya need. for a tool maker to make a rifling setup is easy. to rifle a barrel up to 6 inches is simple. for auto weapons smooth bore works fine. at 22 cal. the bore minus rifling is usually .217 inches. with smooth you can take it to to .219 inches allowing for round compression. if you don't know what i am talking about or do not have these skills, try porting a pellet gun barrel(.22) as long as it has more than 1 twist in 10 inches for a .22 smg. enjoy you fellow sociopaths!
Lol. That looks like mine, and mine is the real deal :) All of the MACs where folded and tacked sheet metal - so all of them have that homemade look.
