I’m going to be submitting the paperwork to SBR my TB UMP conversion (it still has the 16” factory barrel). I plan on getting an 8” HDPS barrel and keeping the stock USC barrel “as is”.
My question is about the purpose/usefulness of the flanged barrel. The threaded barrel is pretty obvious, but I can’t figure out what purpose the flanged barrel serves. It’s not the tri-lug configuration, so what purpose does it serve?
I'm 99% certain that I’ll get the threaded version, but I just wanted to make sure I wasn’t missing something!
