Yet another borescope barrel with chatter question.

[sfotex]

So my pops got me a bore scope for Christmas and we were looking thru my barrels. My WOA and Criterion barrels looked incredible. The US made Century Arms barrel on my AK-74 looked like crap (no wonder the bullets are tumbling) . The BA and Roscoe barrels looked ok. Then we took a look at my new 22" hand lapped 6.5 CM barrel for my AR-10 and it looks like railroad tracks from chamber to crown/360 degrees around. Is this on purpose? Just trying to learn here, but this was a but of a surprise to see. I know the whole borescope/OCD thing, this one just looked 'off' for a $440 barrel.

Not hand lapped lol

Who’s the barrel manufacturer?

That's a copper catcher right there.

It's an Odin Works. Put a few rounds thru it and it already looks like it's catching copper. I will say the tooling marks are consistent thru it.

Holy cow. Yeah, hand-lapped my lily-white derrière.

Have you contacted Odin Works? If so, what did they say?

Button rifled, not lapped. Savages look like that too.

That's a feature, not a bug. Goes in 6.5mm comes out 6mm.

Reamer marks, button rifle chatter. It can but doesn't necessarily affect performance of the barrel. I've had plenty of button rifled barrels shoot sub-moa with FGMM and better with handloads.

The one negative of a button rifle barrel with a bunch of chatter in my experience is faster copper fouling build up and the groups take a few more rounds to stabilize if you remove too much of the copper out during cleaning.

You can smooth out some of it by carefully hand lapping the bore.

Time to get Odin Works involved.

Personally I wouldn't have even fired it ( YMMV ) ..... those marks are like a file, they will chew up every bullet put through it. (As you have seen in the newest photos.)

Sucks you have to send it back.

Please let us know what they say after you send them the before and after pics.

I emailed them yesterday, might not hear from them until next week being the holidays and I’ll I’ll update this when I hear something.

That's pretty ugly, personally I'm probably done dropping coin on OW. My first AR barrel from them is a sweet shooter, my second is ok, but walks with heat, fit for the provided GBs is pretty sloppy, plenty of leakage. Also the hardware I got with my last OW handguard is the super soft playdough junk.... Just kind of a flaccid showing all around.

Call them.

After a week or so of phone tag (they got hit by covid ), I received a replacement barrel in the mail today. It looks much much better.

What would be absolutely classic is if the rough barrel outshot the pretty barrel.

Sometimes a 6 can polish a knob like a 10 should. But the 10 just looks pretty and can't perform.
