Question regarding barrel fitting

[GH41]

IMO.. Bedding, shimming and truing have NO value other than to the plumbers charging you to do it!!!

[grizzman]

All of my builds, precision or not, deliver MOA or better. None of them required heat to assemble. The less than .1" theoretical improvement is in no way worth it to me unless competing at a fairly high level.

100% Agree!

Any replies would be appreciated.... I'm hoping the Centurion Arms barrel shoots well ( as it was purchased used..)

With a good bore scope (good enough for task but not be prohibitively expensive) you can look at a gas port and easily see the difference between something than has never been fired, something that has been 'test' fired and something that has been fired a few cases of ammo worth.

Cheap tool to have considering what a good barrel can cost in comparison.

Plumbers charging us? Some of us are capable of performing these procedures so no one gets charged.

Thank you to all who replied. The barrel I will be using is

https://centurionarms.com/lightweigh...rel-midlength/
As stated it is a used barrel but only had a couple hundred rounds thru it ( no mag dumps) My range would not be any more than 400m maximum for this set up..
I have a 4-5 different loads, all heavy for caliber, ( all factory) to try...I will not be using any handloads.

I will report back soonest once I have completed the build. I fitted a Aero G/B on there ( as I didnt have the Centurion tabbed one) and it seemed to fit snuggly.

I thank you all again for your input... All of you have a great deal of knowledge and appreciate all of your input

Yep, I put all that stuff in the shade tree gun plumber category... People are free to experiment with it, but I've never felt the need for it personally.

I don’t use that stuff on barrels. Gas keys yes, barrels no.

You use Green Loctite on gas keys? Not Permatex 3D?

This is what I use as a bedding / sealant compound on gas keys.

If it’s good enough for SOTAR it is good enough for me.

I level the key surface on a stone and put the 620 on the carrier before mounting torquing and staking.

ETA: I also use OCK screws on all my keys.

If you install the barrel without using Loctite and you don't like the way the carbine shoots, you can remove the barrel and bed it with Loctite later.
