Is bedding the AR barrel a myth? What's the best way?

I give everyone a bad time over "spun up a barrel" or "spin up" a barrel.

It's uneducated porn slang, gang cool, wannabee important, to sell your precieved intelligence on the subject of gun barrels, but instead it's instant explosion stupidity kind of statement...

I spent 35 yrs as a machinist, 5 yrs of apprenticeship, college, and later back to college to machine tool technology to learn programming.
Not "one" machinist, apprentice, or college instructor, shop owner, in many hundreds of encounters has ever used "spin up" referring to anything that you'd likely do with a lathe or mill and a long piece of round stock.
No apprentice or student would get by using "spin up" on the shop floor or in the class room...you would be harshly corrected.
To me it's just dumb ass gangbanger slang or afghan goat fuckers slang, letting your ego of cool talk, emphasize your own stupidity.
It's found on gun sites as a manly, testosterone, chest bumping, cool thing to say,...but it projects the mighty stench ignorance....like a rotting corpse.

Be that guy, and you shutter the window.
All because people don't use the correct terminology certainly doesn't mean they don't how to do something. Kinda ignorant to get so offended by someone saying "spin up a barrel" pretty sure that term has been used alot by some of the best in the business... Don't think I've ever heard a gangbanger use the term either. Kinda just makes you sound like a stuck up machinist, alot like all the "engineers" I've delt with over the years. You know how to tell if someone's an engineer, just wait they'll tell you.

A funny aside, also astronomical odds.

Years ago I was hitch hiking about 100 miles from home and got picked up by a fellow. 5 years later I was driving that same road and picked up a guy who looked very familiar. Same guy who picked me up years before. What would the odds be?

Is bedding the AR barrel a myth? What's the best way?

As I mentioned, if you toss in "accuracy & precision" into the main goals of the build, then you aint using a sloppy fitment and 620.
If we are trying to gain 0.1moa on a decent dry fitment from low-cost low-effort procedure, then so be it. I think the goop does help stabilize the fitment during heating cycles, so you get whatever gains there are to be had, but there's little diff in gains between any of the bedding goops mentioned thus far. And then we factor in other things that can basically shadow out the small gain from goop, ammo/barrel/shooter.

I sure hope readers know all the work to bed is not something you see from 1-shot per target trying to match poi of sights. Any gains made can only be measured in groups of shots on same target. Almost all of the movement of barrel happens after the bullet has left the muzzle.

And then we have Camp No Bed. Makes it hard to sleep at night. Happy bedding. ;)

Bartlein Barrels Update

How does a tariff on import affect your prices? Are you importing the steel?
Doesn't matter if we import the steel or not.... even raw material to make the steel gets imported to some extent depending on what it is... so no matter what prices are going to be affected.

Also think of this... ingredients that go into our coolant for the lathes has iron in it as well... I'll go on a limb and say were going to get hit with that for a increase at some point in time as well. It happen during Covid.... our coolant cost jumped 30% without any heads up... was just told.. "your next order will go up 30%". All due to material costs.

Also material surcharges are not added to the base price of the material and those prices are based on current market day exchange rates. Any of the grades of material like copper for example that go into the mix of the material.... we don't know those prices till the day of shipment/we get the invoice.

Rifle Scopes March 5-42 Gen 2 PRS Edition

Thanks for that Deny. I wonder if the glass is similar to the floride Ed that Kowa uses, which is known to be among the best money can buy.

I spent a summer at atterbury before going to Iraq and that place is brutal that time of year. Mirage in an ACOG was nasty at 300m so I can only imagine at distance.

I have a new ZCO 840 getting delivered next week but it sounds like I need to snag one of these new March PRS scopes to give a spin. The mirage was horrible last weekend with a zco527
Kowa uses glass that has more floride that most rifle scopes would allow due to being more brittle but it is one the reasons the Kowa lenses in spotting scopes are so good.

No difference in glass between the two ZCO models as far as I know.
