I've got an old RRA upper that I'm going to re-barrel to Grendel & was going to lap the upper to make sure it's nice & true. BUUUUT, alas Wheeler has put that one single item on my order list on backorder with no immediately available eta.
Based on the level of experience & knowledge base on this site, have y'all found RRA to be pretty dang good about their uppers being true, or do they tend to be a little "off"?
I wanna build this one right & don't want to have to re-do it just to lap in a month when I finally get the tool. Other side is, I also don't wanna wait a dang month either! lmao
Appreciate advice from the wiser Horde!
I believe most uppers are cast and not lapped before assembly for mass production guns or complete uppers that most companies offer. I would suggest canceling that item and ordering it through another vender that has it on the shelf. Amazon has them and you can have it in a couple of days
