Spitballing...So who’s running a 12.5-14.5” 308 AR?

I see mostly carbine gas on 12.5’s and a few 14” barrels. Seems brutal and a lot of talk about this. Seems a mid length 13.5-14.5 would be ideal..Seems easy enough by grabbing a 16” mid length and cutting it down

A shorty 308 Is intriguing me as my 18” build is just a heavy mofo and no deserving glass for it, as it got
A lot heavier then I wanted. 14lbs is no fun to pack around hunting/exploring.

Also ballistic wise , throwing 150’s at 2300’ish down range and 110/125’s at 2500 + will do a lot of damage

So who’s running a short barrel 308, and what have you done to tune it so it’s not bearing itself apart?

Pics are good too..
