So I just want to thank everyone for all your input and help with my 300 blackout rifle. Unfortunately I had to send it in to Ruger, and was just notified by customer service that production on that rifle has been suspended and they are unable to repair my rifle. So now I'm to choose a new caliber rifle from there website so they can send it. I'm so disappointed with this situation right now because I have spent $200 on various items for that rifle, which I cannot return.
