Barrel Nut Torquing?

[montana]

Montana,

On the Bison link video the shim is being inserted between the receiver and barrel extension. He snips his shims to do this.

Regardless, using words like ‘Bubba’ and ‘mangle’ are freighted with the assumption we don’t know what we are doing. As I wrote, I’ve removed a tooth before and it works. I’m with Bonus on this one. Why risk the critical receiver-extension interface for the sake of lining up the gas tube. Alternatively, removing a tooth preserves the interface and is easier and cheaper.

Note also in the video he only torques to 30ft lbs and not up to 80. That acceptable MILSPEC range could align the tube without needing to buy his shims.

Mangling a barrel nut when not needed is not considered quality work where I'm from Klem, but people do have different standards.. If you purchased a new rifle and the manufacturer ground off one of the keys to reach torque spec I'm sure you would be A-OK.. I wouldn't be, I would ask for a refund....

I did watch that video a while ago before they turned off the comment section for a reason.. Putting shims between the upper receiver and the barrel flange, is doing it wrong..

I know all about your opinion on quality work, such as shooting questionable loads from behind a tree, sand papering the boat tail to remove carbon and grinding out the aluminum upper receiver feed ramps while simultaneously removing the hard anodizing in the process..

One thing I do know is there can be a lot of contention between AR building procedures between the so called experts..I know I don't agree with any of them 100% of the time, even those I respect the most.... I just take it with a grain of salt when certain people get triggered by mine or other peoples opinions..What I call Bubba work you and others may consider top notch gunsmithing.. That's whats great about the USA, having an opinion and the right to choose who we listen to..In either case it is no skin off of my teeth what you or others do with their rifles, I'm not in a popularity contest or care what the latest consensus is..People ask for opinions and I give them mine.. They can choose who they wish to listen to or not.. Have a great day Klem..
