Ar15 conversion to 9mm?

[clintbailey]

So I have a 12.5" AR pistol chambered in 277 Wolverine that I never shoot, and decided to part it out. Had some Wolvy guys interested in barrel, but not full upper, so I stripped barrel out. Now I'm wondering how hard it'd be to convert to 9mm? I saw a place with 9mm uppers on sale, w/bcg and ch today, but not sure what else needs conversion besides magwell?? Any input would be great, even if its saying "don't do it"

Complete 9mm upper and mag well insert to hold whatever kind of magazine you decide and you'll be good to go!!

9mm uses a heavier buffer and some folks use a .308 spring. It doesn’t use a different charging handle so you can use whatever one you like. Magwell adapter for whatever mag type you want. Colt style or Glock are the two I know of and Glock is more popular these days.

Yes that works, cmmg makes a magazine conversion. You take the guts out of a pmag and install
the kit. It will work with a standard buffer and spring as well. You can get a complete upper
or install a barrel on yours. Just make sure the barrel you install has a gas port, some 9mm barrels
do not have gas ports, and run off from blow back which requires a different buffer and spring
