    Just got my NAA 22 mag today.
    It looks like copper shards fused to inside of my barrel. Never seen this before.
    A few pieces fell out but theres two rough spots. I'm soaking with some Sweets 7.62 right now.

    Some kind of bore Flaw, like a chipped cutter and coppers building up like a sheet.

    That's just my guess from what I can see, a bore scope would be handy.

    I was able to make some headway trying different cleaners. Hoppes seemed to work best, big chunk of copper shard came out and theres only a very small piece left in there. Unfortunately my brush is destroyed but I'll go get some new ones from cabelas in the morning.
    Here's some better pics of the bore before I started cleaning again.

    After 20 mins of vigorous scrubbing this came out.

    Which brings me to wonder.
    Is the bore too tight, or the bullets in those test rounds over sized to be able to shave copper off the bullet like that. The chamber alignment on the cylinders to bore look good to go imo.

    It certainly can't hurt to email them.

    Something strange for sure, that copper is huge . What ammo did you use and did you try more than one ? I would surely give them a call, this could be a known issue and could also be ammo specific .

    Could be the light but it looks as if there is a raised edge between the grooves in that area. It seems to run the circumference of that area if the barrel.

    Those are chatter marks and they are shaving copper from the rounds you fire. Contact NAA.

    That barrel should have never left the factory. I'm afraid the next time you shoot it you will be doing this again.

    It appears to be machining defect that was left by the reamer. Went in crooked and gouged out a section since it looks to be more on one side than the other.

    Went and shot 50rds of CCI MAXI MAG 40gr TMJ.
    This lil sucker is bad ass, I love this thing lol.
    First shot caught me off guard, almost flew out of my hand heh. Haven't shot a handgun in over a year, but this little guy was printing well.
    I checked the barrel and see no indication of copper pieces so it probably was the ammo they used for test firing at the factory.

    Time will tell,Good Luck! ( But makes me wonder what the factory is using to test fire.)

    I'm thinking lead free green. When they contact me I'll ask for details.

    I am curious of their process now, the radial “rings” being in both on top of the lands and down in the groove must have come from the rifling process they use. Looks like you’ve taken the lands down enough to get rid of the offending ones.

    I think yet another example that .22 mag is "different". Little in general about other calibers necessarily applies to .22 WMR and little specific about .22 WMR applies to all other calibers in general. This is what makes .22 mag interesting, challenging, sometimes frustrating, but yet ... mostly ... FUN!!

    I think the hardest part if figuring out how I'm gonna carry this gun as a backup.
    I usually carry a lcp in my pocket, so I'm thinking of getting a driving holster for my belt or getting the folding grip and carrying on my waist or back pocket.

    Motor oil has detergents. Try letting the bore soak overnight, in some Mobil1. Then patch it out. Leave the bore lightly
    oiled, this way, till the next time you shoot. This process may help dislodge any foreign particles.

    From examining the grips, they are rosewood factory grips that naa has applied some type of paint pattern.
