Looking at a SBR in 5.56 and would like to run a suppressor. Already have the lower, just trying to figure out which barrel length is best to run with suppresor in 5.56.
Already working/have the 300SBR. Want to build a compact 5.56 SBR that's suppressor ready.
What about this option?

10.3" minimum for 5.56.
11.5" is better.
9" is fine for .300, but you want the longer barrel on 5.56. Better muzzle velocity, ballistics, and recoil impulse.
