In my opinion, no one who works on competition guns know anything about a screw. The only way to get your screws right is "small claims court". Don't send the gun back to Briley to fix the screws.

Bill, I disagree. Briley has some very good people there and if you call and talk to them and explain what happened they will make it right even if they have to send it out to someone else. I had a similar problem, not with a screw but with a trigger and they kept after it until they got it corrected and they were polite all along the process. They even paid for the shipping both ways. They make mistakes like everyone else, but they will stand behind their work.
