Bedding an AR barrel

[1shot]

I ran into a guy on YouTube who was lapping his action and then bedding his barrel extention into the action on his Ar10. I had never heard of this before. Does anyone have any experience with this? Does it really help squeeze that last ounce of accuracy out of an AR?

[Outbreaker]

I “bed” every AR barrel with loctite and it works well.

Bed actions, float barrels. You want the harmonics of the barrel to move freely. Bedding a barrel would also cause all sorts of weird things to happen as the barrel expanded when it got hot I would imagine.

What do you bed the action or the barrel to?????

[J.B.]

LOL, so confused here... how do you bed an AR in any fashion?

Nothing on an AR. Just a general statement about rifles.

This is your problem. Unless you can verify the persons credentials take their “advice” with a grain of salt until you can prove or disprove the info.

There are so many people posting instructional stuff on YouTube that have no business doing so.

For those that have never built an AR upper (seems like a few here with these comments)

The barrel extension mates into the upper receiver. This can be "Bedded" to remove any slop in the union. It is not a traditional bedding like is done in a bolt action rifle.

What I do is use loctite at the union to make sure the barrel never moves or shifts. This along with bedding the gas block the same way and pre-stressing the threads on the barrel nut before the final torquing will squeeze some extra accuracy out of the AR system.

I've built several AR's and never heard of it and I thought is seemed crazy, so I understand thier coments.

This was taught to me by someone who is as OCD about accuracy as I am.

I took a factory gun that was 1.25-2 MOA at 100yds and by doing this got it to a .5 MOA gun.

The factory gun already had the barrel floated.

So you “bedded” the barrel extension and left the barrel floating and that made the gun a .5?

I’m gonna shoot you a PM about this

The barrel and gas block had some slop. When I was done it was motionless.
