POLISH AN LW POLYGONAL BARREL?

I gave the muzzle end a thorough cleaning (because it was easiest) first with Gunzilla and then with BoreTech Eliminator (a firearms solvent), both applied liberally with cotton swabs and scrubbed with a nylon brush. Here are pictures from after (compare to first pic above). I see no difference and didn't see any material on the dry cotton swabs used to clean the solvents. I'm open to other theories but I would have expected any lead to be removed.

Absolutely bad pitting. Was the gun used when you bought it?

I still see brown rust. Switch to the brass brush to be remove it. And use a bigger grit polish.
Dont fear the brass brush.

Little science for you. Brass is MUCH softer than steel.

I’d request a new barrel

I've sent AGT an email and they would like me to ship the barrel back to them for inspection, and they'll determine if it's a factory defect 🙄 I was hoping they would just send me one so I wouldn't be without the rifle for 6 weeks. I bought it from Talon Tunes, and they clearly don't want to be involved.

Frankly, it shoots better in my limited testing after I polished it. I'm going to shoot it some more, and at distance, and if accuracy has improved despite the pitting, I'm just going to keep it. It sucks, but I'm not competing with this rifle, and if it's MOA at 100 (it was about this already) I don't have much to gain. I would just be proving a point. And I'd rather have my coyote hammer at the ready :)

lol. The pics are quite telling. No way they can blame that on cleaning and or polishing.
But I wouldn’t blame you for keeping it if it’s accurate. But it would still be a hard pill to swallow.
And that seems bad of Tony to not want to deal with it. HE sold it to you. HE should make it right. Pretty cut and dry for me.
And sadly I was looking to buy a rifle from Talon Tunes because of the several glowing reviews on here lately.
But him pushing the problem off on you is a huge red flag for me. I won’t be spending my money there.

To be fair I bought it about a year ago, but yeah, I just got an email back saying to contact AGT directly.

Not a poligonal but an FX liner (a first out of six I have and I was planning the exercise).
Borescoped, firelapped with Clover 280, moped with 280, borescoped, and pushed the pellet in and out, and casted a plug and lapping now with it 280.... all these hours of effort and I am on the borderline I need to stop somewhere., and soon...
If this would be easy everybody would do it.
Today morning it was 3C in my garage, I am running a 4000 W heater for an hour already, I wanna give it a last try :)

It seems normal for him to not deal with issues, thats what stopped me from making a purchase. A good company is measured how they deal with issues after the sale, anyone can prep it, through it in a box and ship it fast. SPAW is the same way, have a issue…crickets.
