Folks,
Anyone know for certain the thread pitch on the .223 variant of the Ruger Precision Rifle muzzle?
I'm reasonably sure it's 1/2"x28tpi, but I've seen some references that suggested 1/2"x24tpi.
From what I can figure out, the RPR .223 barrel should be the same as an AR-15, which should be 1/2"x28??
Thanks in advance,
Rod.
