It seems like the 12.5” is not as developed a system. People used to say that about 14.5” midlength, too, of course.
I’m curious about BRT’s possibly EXC for a 12.5” barrel.
12.5 any day.Quote:

I voted 11.5" carbine gas because that's what I have experience with. I've never owned a 12.5" mid length.
I have an over gassed 16" PSA mid length CHF barrel that is just sitting in a box, I'm thinking of chopping it to 12.5" and seeing if it will still run reliably with that blown out PSA gas port.
Why not 12.5 carbine length? I would go with 11.5 between the 2 options you listed because I know it works. A 12.5 carbine will run well too
I haven't done any shooting with a 12.5 middy but mostly what I read is it is usually in a suppressed set up.
Centurion now offers a 12.5 middy and that would be the first place I looked. Not sure about port sizing etc, but BRT would probably have that figured out of they offer that configuration
You've nailed my dilemma. I've had a BCM Kino and that may up being it again. The Centurion middy is the barrel I'm looking at.Quote:
