So a couple of questions for ya. If ya drop this on a Colt receiver, will she run without having to change buffer springs?
What is the ID of the handguard? Can a suppressor slip inside it? It appears the barrel threads are well inside the handguard.
I would like to work out some trading with you if you can't find anybody local. I'm in Texas. I can look when I get home to verify what type of primers I have and send info to you if you're interested.
