I just submitted a Form 1 for a [stripped lower] AR-15 build (.223/5.56) with a 12.5" barrel (OAL 29.1") intended to be used both with and without an Optimus silencer. I'm wondering if I could get away with a barrel that's an inch or two shorter without seriously affecting both reliability or muzzle velocity? Anywhere around ~10.5"~12.5" is fine. I just wanna see if there's a sweet spot in there that I should be aiming for?
I realize it's difficult, if not impossible, to gage ideals without identifying a specific purpose or task for a given build. Still, I wanted to see what the pros and cons are?
