I did a search and can’t find the information on here.
So when putting together a few of my last builds some of the barrel nuts didn’t require shims and some have. Of the ones that have, they always have lined up perfectly for some reason on the first try…
I am doing some reasearch and realized there is some confusion on the placement of the ships. Some guys on YouTube place them between the barrel extension and receiver. Which I tried on my latest and got it to fit much better.
My previous build has them under the barrel but and shredded from being caught in the threads when turning accidentally.
So which is right? And does it matter?
