The Colt Canada AR manuel I have says to only torque a used barrel once instead of 3 times onto the upper receiver. But anybody know if you are supposed to torque once or 3 times for a used barrel with a new upper receiver? Thanks, -Pete

It seems as if Colt Canada already answered this...
Interesting. I have not heard this before.

This is a new one to me as well. I would do it the way that has been tested and torque or tighten it at least 3 times.

Somthing I thought of, and I don't know if the Colt manual makes a distinction; would you be putting it on a new or a used upper receiver? I doubt the threads of the barrel nut stretch, but I would imagine the upper's threads would have more give.
Edit:
Colt Canada Manual under page 3-2-16 section 14 "Rebreeching Existing Barrel"

BP7178, It's a new upper receiver but used barrel. Thanks, -Pete
I never said that. I said that the manual doesn't differentiate between new and used. It was rather rare in my experience to replace the receiver and barrel at the same time.
The same technique was used whether it was an old barrel/ new receiver or a new barrel/old receiver or both it mattered not.

Whenever I'm using a new receiver I torque 3 times. Only once if the receiver is used.
