BRT OPTIMUM Barrels

[Dr Dues]

MOLON......

Still waiting for your test results.....

Time frame???

Teslong bore scope, the bane of barrel manufactures. Lol. Cheep and accessible to give people just enough knowledge to hang themselves and cause publicity problems.

Point being small burrs in the gas port and artifacts in chrome lining, shines and dull spots are common from ALL of the big fighting rifle barrel brands. Not going to drag Clint at BRT over it. It would be cool if all bores looked like a polished Criterion but even their barrels aren't always perfect looking under the bore scope.

I have gauged BCM barrels that had blown out bores. Centurion barrels that had horribly loose chambers and wicked gas port burrs, Sionics barrels with short headspace. All of these things are more important than a few artifacts in the chrome. These barrels are not single point cut, hand lapped stainless barrels and despite what anyone thinks none of the big manufactures have 100% QC on every detail when the intended performance is a 2.5 moa fighting carbine.

Yeah......

ALL of the above....

The lack of response to my request speaks VOLUMES.......

All of that is why I still run Colt 16” carbine gas barrels.

They may send out lemons too, but you have to look for a looooong time to find one.

What are/causes the “spider leg artifact”? I tried an internet search and found nothing.

Maybe a worn out mandrel or reamer.

Maybe, but I don’t think so. They look negative in Molon’s bore scope pic. Like pieces of wire were stuck to the mandrel, which I also doubt. The sort of artifact that I’m used to seeing on a CHF barrel is drill marks that sort of look like chatter but are hammered flat. Its pretty common.

Bore scope pictures are like EEGs. They provide a visualization of things, but most people don’t know how to interpret them, so it all looks bad, without necessarily being bad.

I can attest to that. My colt 6940 even has the yellow qc mark on the barrel. The barrel shoots like a dream. I've had so many bad experiences with barrels from a few different manufacturers that I'm not sure if I will ever shoot anything other than a colt or fn chf barrel.

Yeah......

ALL of the above....

What request? From Molon? Molon doesn't get paid to do this. He doesn't owe any of us a god damn thing, but I'm sure glad he puts his time into the reviews he does.

I don't see a request from you to Clint, the manufacturer of this barrel.

Scoping a barrel WITHOUT CONTEXT (that would be a live fire exam), is meaningless......

The worst part is that this half-baked exam came from someone who ALWAYS gives a complete picture....

THIS TIME..... not so much

The level of entitled hubris in your posts is pretty astounding. Molon doesn't owe you jack. And the fact that someone of his reputation for thoroughness hasn't expounded on his findings, here in the forum, should give you a clue... But you're too wrapped up in the fact that he didn't respond to your demand. Who the eff are you?

Ever stop to think that maybe he and Clint took the conversation offline?

Thanks man.. beat me to it.
