Been throwing around the idea of building a 9mm ar15. What barrel length would yall go with? Im thinking 8 inch (pistol lower of course) the 4.5 looks pretty good tho.
I sent you a PM about building a pistol right now but I’ll throw in my .02 about barrel length. I have a handful of AR’s with different barrel lengths. To me anything under 12” just isn’t ideal when it comes to handling the gun. I like my left hand to be pretty far forward on the handgrip with a c grip. On my 10” barrel my hand feels like it’s right on the mag well.
