Also, you said it's a Satern 18" RLGS. Are you sure it isn't a Satern 18" MLGS?
What's your gas port diameter?
Yeah I was mistaken... It’s 18” and mid length gas. Don’t know gas port diameter. Whatever they punched it at is covered by adjustable gas block right now. Never bothered to check gas port diameter.
