AZS Experts -

Are any of you familiar with, or have experience with, an MK ARMS semi-auto version of the MK-760 SMG (S&W M76)?

It looks like this:

There was not a lot of info on the net. I could not find any completed auctions on GB. There was one auctioned in 2006 by an auction house known as "Rock Island Auction Company."

I think it is the same carbine version as this one currently being sold on GunsAmerica:

I can't imagine, however, this folding stock version being valued at that price point ($3250) and wonder if there are some different versions or nuances.

Any insight from previous owners, or suggestions for further research, would be most appreciated.

Thank you!

I have had one for over 15 years. It has remained in the back of the safe. I am sorry, I do not have any info either. It is a cool little carbine. I am embarressed to day I do not think I have ever had it out to the range. I think I have 2 or 3 mags for it too.

The extractors on these are notoriously weak and prone to breakage after only a few thousand rounds. Spares are nearly non-existant,...BUT,...Toad Bailey over at Speshul Weapuns did produce a copy of this gun, with an actual improvement to the original design, whereby he moved the extractor from the 12'oclock position on the bolt to the 2'oclock position, as well as being being beefed up. He may still have spare parts in inventory.

UziTalk.com has a sub-forum dedicated to these, but mostly the focus is on the machineguns, not so much the semi-auto. http://www.uzitalk.com/forums/forumdisplay.php?f=87

Seeing Toad Bailey attributed with the product improvement of anything gives me the shakes.

Don't worry, he probably made some with extractors at 1,3,4, and 9 o'clock also. Probably not an intentional 'improvement', just poor QC ;)

The one's with the extractor at 2 o'clock were probably the only ones that didn't end up in the scrap bin at SW's 'warranty' department [smilie=icon_lol.gif]

What the hell $3250 I paid less than that for one with the fun switch 5-6 yrs. back it is worth maybe 800-1000 you can get extractors barrels etc from a company in az though only off the net. no storefront, (black market parts) don't remember the website there or at www.samachine.com They made carbines pistols etc open bolt semi. and sub-machine guns. uzitalk has quite a bit of info.

If you're looking for a wannabe SMG with a long goofy bbl and a tricky stock, the Century Sterlings are less than 500 bucks and the mags are easier to find too.

I have to say it, even though I wrote up a three paragraph follow-up to this post and at the last second zapped it for changing my mind. The reason was, I really don't like to bash, but I see this now as a heads up for others.

MK Arms made junk, pure and simple.
I thought that since it was an S&W design, it would be good, I was wrong.
They cloned a design not even as well as Iver Johnson and Universal cloned the M-1 carbine.

-Misaligned trunions (depends on the day it was built)
-Bolt metallurgy is questionable as the bottom lip likes to crack and bend
-Extractor likes to fall apart which seems like not only metallurgy, but the design of it sucks
-Their factory mags have to be fitted to each gun (pathetic)
-Reliability depends on the day it was built
-The sear likes to wear fast
-Bad trigger pull
-If the sights are off, sucks to be you

If you got one built in 86, you are almost guaranteed you landed a turd.

I sometimes wonder if the gunsmiths at MK Arms landed jobs at CAI.

Funny...probably true
I have owned a number of these in FA and none of them worked as advertised.The are an extremely poor copy of a S&W 76, which also was a poor copy of a Swedish K.

I had the one sent to LaFrance twice and it costed more to have it fixed twice and have the mags fitted than the original price of the MK-760.

After all of his pricey work, it still would not shoot more than 2 shots in a row.
It was apparent after the new extractor, trunion removed, supposedly aligned and rewelded on and two times of repairing cracks on the bolt and even with the mags fitted, trying 4 brands of ammo that it would never work right or even that long before it would not work at all. (I know, big time run-on sentence)

I still can't believe how horrible these things were, and I know I was not the only one as you and so many others on the net have complained of the MK-760 too. I even watched a video where I can see the trunion is so far off, the barrel was aiming at a harsh angle down!

I forgot to mention, the barrel shroud always wanted to unscrew thanks to the crap shroud retainer design.

I guess I was lucky I had a FA MK 760 for 10 years never had a problem with it or Suomi mags. I've put thousand of rounds through it. Scot Andrey makes spare parts if needed.
