Agree 100% here.
The 14.5 middy and 12.5 CAR have exactly the same distance from the gas port to the muzzle.
With properly sized gas ports for each, they’ll both run great and be equally smooth.
The 12.5 and 11.5 CAR are great combos.
Can you guys make at least one suppressor that sucks to make my decision easier? 
This is the one you want: http://www.store.silencerco.com/products/hinderer-knives-silencerco-blackout-package
Trust me…the package is beautiful!
I will always have a 12.5" carbine length gas AR in my collection. Here is a BCM 12.5" upper with KMR10 set up in mini-recce configuration.
That package does look good. I had just about decided on a saker but now the lighter weight of the omega has it in the running for my 11.5 I’m building.
I wish I had a different suppressor than my SPR/M4. I would pick up an Omega for my 12.5 if I could redo things today.
