M3A1 "Grease Gun"

    Does anyone own a "Grease Gun"? I may get my hands on one pretty cheap, and love the idea of owning one, but have questions.
    Are they all fully auto? (I think they are, but not sure)
    Are they made well enough to shoot without concern?
    Thanks for any help with this. Not a very popular firearm. - CO

    If it is transferable as a registered NFA weapon then it will not be "cheap".

    If it's cheap it's probably either a) illegal or b) semi auto.

    Be careful.

    Beyond that they are reasonably reliable, not accurate at all but who cares, its a sub machine gun......

    My concern is that when you use the words "cheap" and "legal" and "full auto" in the same sentence that something is missing.

    A legal transferable M3A1 should be priced around $18,000-$20,000

    It's got to be a semi-auto copy if it's cheap. Plain and simple.

    Did they make any semi-auto copies and if they did do they shoot from an open bolt? If so it might be a bargain. My understanding is that open bolt rifles made prior to 1982 were grandfathered in. I don't know how collectible a semi-auto grease gun would be, but I'm guessing that a legal open bolt version would be worth something. It'd be a funny looking grease gun though if it had a legal length barrel on it.

    An open bolt semi would certainly be worth some money but yeah, it's gotta have a 16" barrel on it :)

    Just be aware there are unregistered MG's out there and possession of them is a Felony.

    Now, if the gun has a 16" barrel on it, I'm sure it's some sort of semi-auto only replica.

    But, if the gun has the standard short barrel, and fires from an open bolt, it's contraband UNLESS they have the NFA registration papers for that gun. If they do, there are specific forms and procedures you have to follow to buy it and get it transfered to you.

    Even though most MG's are expensive, now and then you find a deal. A friend bought a registered PPsh from another friend of his, a Korean War vet, for $1,000 a couple years back. The guy knew he could get more for the gun, but sold it to a friend cheap as a favor.

    The web site referenced above lists a "US M3-A1 Grease Gun - Pistol Version" with an 8 inch barrel and no wire shoulder stock. I’m thinking it would be pretty difficult to fire the weapon pictured without a support hand on the magazine or the barrel (ouch, that’s hot.) Would the magazine count as a forward hand grip, making this an AOW?

    ATF has exempted mags from that rule, same would apply to AR and AK pistols.

    Years ago, I carried a "grease gun" as my side arm instead of 45 Colt. My job in USMC was automatic weapons specialist; I carried a M-60 over hill & dale.

    USMC armorers worked this baby over nicely.
    - magazine well polished
    - magazine springs replaced
    - trigger tuned
    - fixed sights adjusted
    - internal parts polished

    Was it accurate? Sort of. We're talking about a full auto 45.

    Was it dependable? YES!

    Was it lighter than a Tommy? YES!

    What happened to the thousands that were built during WW2? Given away as Foreign Aid or cut up and sold as scrap steel.

    Here is one: http://www.autoweapons.com/photos07/jun/1941grease.html
    e-mail for the price,

    How about a brand new one (original that was never fired)?

    How about this dealer sample (you need to be a dealer, etc to own it) It's less than 9K

    The ads are out there, you just have to look.

    Of course if you want cheap: http://www.autozone.com/selectedZip...il/initialR,NONAPP5854/shopping/selectZip.htm

    I got to qualify on one of these in 1996 in the Army because our mechanics still had them and I was in HQ company with relatively little to do. I was shocked they were still in inventory. It was a blast and the qualification was a joke, more a test that you could fire it safely than any sort of accuracy test. Shortly after they were taken away and the mechanics were issues M9's. I'd take one if the price were right and legal, would be a fun shooter.

    That Valkriearms link above (#7) has me thinking...

    Does the open bolt rule apply to long arms only or pistols, too? If only long arms, it would seem to me that there would be a lot more cheap, semi-auto, machine-pistol-like handguns out there. After all, how expensive could it be to make a semi-auto Sten with even fewer parts than the original (no stock)?

    Yeah, If you're going to put your hand near the barrel you should get one with the shoulder thing that goes up.:D

    41magsnub- When I was in Germany in 1992, we had a locker full of them for the tracked wheel mechanics. I never got to shoot them, but they were on the property books for $8 and some change. (Our 1911s were valued at $58 after adjusting for 45 years of inflation.)

    just for a little balance here....

    dunno who may be aware, but the butt ugly little M-3 was the ~ONLY~ U.S. sub gun to ever pass the Aberdeen Proving Ground "mud, blood and crud" test. it has twin recoil springs on guide rods the bolt rides on. hence, NO contact with the reciever, as in armalite AR-180 and AK 47, but the later has one single recoil spring...kinda hard to stop one up with mung and spooh.

    as for accuracy, didja ever shoot an open bolt ingram/MAC in 45 ACP? they aren't made for bench rest shooting. they will fill up a doorway pretty fast with 2X 9mm bullet weights at bad breath ranges though!

    my understanding is that valkryie bought out the rights from an outfit in olympia, WA. owned by a woman, can't recall her name or the company, but the sillyvillian version was a closed bolt offering. this would help accuracy, at the sacrifice of additional moving parts. i would prefer one of these to a semi thompson as they weigh in at a "biggest loser" start off point of 13lbs. also, unless one is blessed with a steady hand and a deremel tool for milsurp mags, Kahr magazines are pretty spendy. but the Kahr can be converted for govt mags for about $60.

    still, a niche offering. mighty fun but no real practical use. personally, i would look at a a mech-tech 1911 upper over this myself. at least they can have a decent trigger.

    Last I knew the army still has like 750k of the things in storage. That would make a great fire sale.

    As far as the ATF is concerned anything that fires from an open bolt is a "machine gun" and illegal. Doesn't matter if it is a rifle or pistol. This is because if a gun is designed to fire from an open bolt, to few things have to be altered or break in order to make it full auto.

    I had one as a tank mechanic / 88 crew back in the middle-late 1980s. We spent a lot of time crawling around in the mud, and I loved knowing it would work when I needed it to. The darn thing was ugly as a track pad and just as reliable. You might try an airsoft version first to see if its anything close to your cup of tea, though. Pretty basic piece of hardware and not that easy to enjoy.

    That's only for new manufacture. Anything made AFTER 1982 can't fire from open bolt but anything before then is OK.

    There were plenty of things made that fired from open bolt that were grandfathered. Owning something that fires from open bolt does NOT make it a machinegun on it's own.
