    yesterday i talked to dennis from gmb and he said it's machine finished oversized. he said he'd try to get a picture and the measurements on the gm website within 24 hours he said their whole idea behind them was the home builder with lathe access pretty much so we can make our odd ball barrels easier (tabuk, long akm, etc)

    I wonder who will be the first one to chuck one of these up in a drill press and finish it with files and sandpaper, you know it's coming.

    "get as much as you can for these barrels Jenkins, or you're fired"
    LOL

    Yeah I took a chance too and ordered one.
    Since I don't have a lathe, maybe I'll be the drill press guy?

    I got an email from them today. The barrels are 1"x20" unchambered non profiled .310" rifled blanks. I have no idea why they advertise them as 7.62x39 when that is a chambering. They could advertise them as 7.62x25 or 7.62x54 or even 32 ACP for that matter.

    Mildly deceptive but it sound like a fun project still. I guess I'll need to get a X39 reamer now. I wonder if they'll have them for sale at GM in a day or so. They have pics up now also, that would made things a lot clearer from the begining. I was going to pick up a few of them but I think one will be enough for now.

    I just got off the phone with Dennis at GM. The first thing he mentioned was that, despite what the web site says, they're not chambered, and he apologized about it.

    When I told him I'd heard about the sale on gunco, he asked if I would mind posting something about the chambering thing.

    Most of GM's barrels give a typical cartridge, like ".40-65", and I've had to look up the cartridge specs to guess what the size of the barrel was, so it's consistent, if misleading.

    Anyway, they're straight 1" rifled tubes, no taper, steps, tenon, or other machining. I bought two. He said they've sold a ton of them in the last couple of days.

    He said the price should be good all summer, and that they were going to greatly expand their lineup of military-style barrels. The ones closest in the queue are various AR-15 barrels.

    Wow, I was going to get after it with my dremel, but that sounds like a much better idea!

    Sweet. I have the reamer for the x39 an at 1" they would work on some bolt actions (not remington 700) like the mosin or ruger or win. I see a 1" bull barrel target build coming soon that will also shoot factory loads. Now I need some one to make cheap over sised gas blocks or a sagia shot gun clone. If there decent I may get a few and chamber them and sell them possably. a 1" bull barrel mosin would be cool.

    there add is very missleading it says profiled and also 7.62x39 which it is not. I hope they come out with some 5.45 blanks also in the same price range Id jump all over that.

    Yep, got the email too.
    I agree, they should have mentioned about the "no chamber" thing, but oh well I'll send it to 1biggun and let him do it.

    I think it's a good deal yet and not bitch about it.

    Being a barrel blank It does open up some possibilities. I wish it was the longer blank that they use to make the rpk barrels, but I guess beggars can't be choosers.

    I have a 1895 Chilean Mauser that that would be a nice conversion to 7.62x39.

    Could do a heavier barrel psl carbine....
