I just got a P&S ras and was trying to install it in my rifle. For the life of me I cannot the rail under the delta ring. And there are gouged in the rail where the barrel nut appears to be preventing the rail from seating. Any ideas?Attachment 53336Attachment 53337Attachment 53338
I've already insured the screw is removed and the gas tube rails sit on either side if the gas tube. And it applies to the bottom half of the rail as well as the top.
I have seen this happen with barrel nuts that weren't timed properly. What upper are you putting this on?
A BCM. I figured it would be good to go.
Anyone have any ideas on how to fix this?
Nope, have you seen these:Quote:

Do you have a hand guard removal tool: https://www.brownells.com/gunsmith-t...prod24202.aspx
I'm simply asking if you are sure you are getting the Delta Ring as far back as it needs to be.
Good luck.

Have you considered having someone else look at it to rule out operator headspace?
