12.5 inch barrel vs 13.7 inch barrel velocity

[jnr4817]

I teach medical applications (officer down/rescue) class and it’s 2 or 3 days depending on the customer. Round count is usually 500-600 rounds per day, rifle and or pistol. Never had an issue. She gets pretty dirty, but is loved and clean regularly. I run a bcm mk2 buffer and h2 equivalent. When I get my suppressor I’ll tune her appropriately.

I bought this back in 2014 but never installed until a few years ago. I’ve had no issues. It’s probably not the best barrel but I didn’t know what I know now. I had all the parts laying around so I threw it together.
