What about them?

Do you feel like they are on par with the S&W guns?

I have a MK760 and absolutely love it....the key is good fitting mags and a spare extractors......super controllable and if you are on a budget like me a great deal.

The MK series guns seem to in general have more problems that the S&W guns based off all the posts and conversations I have had over the years.   Conversely, I don't really recall anybody reporting significant issues or having bad things to say about the actual Smith made guns from a reliability perspective.

That said many of the MK series guns have been fixed over the years, now run very well, and do represent a decent savings over the Smith guns.

For me when I bought my Smith 76 the monetary premium was worth it to get a gun that had a better reliability/quality reputation.   For other folks they may have a better place to spend that $3 to $5K difference between a Smith and a MK.

My only advice if buying a MK series is to make sure that it runs well and also runs with multiple different magazines.   If you get one that is a problem child MK you may eat up a bunch of your initial purchase saving sending it off to be fixed.

I would agree with the MKs, you need to be careful especially with the versions serial number that do not start with S(submachiengun) the ones like C (carbine) or P (pistol) on the serial number from what I read and heard they are last minute 86 MG ban conversions and some were not done really well.....I am not a gunsmith or expert but if the gun runs well you should have no issues, it is not a complicated weapon.....just replace the springs and extractors......

I've never fired nor handled an MK760, but from what I understand their reliability is hit or miss albeit better than the Stemples. Meanwhile my S&W 76 has malfunctioned exactly once (and it was with ammo I least expected to malfunctions - 124gr RN NATO.) A high priced MK760 and good deal S&W 76 are within about a thousand dollars of each other...I've seen MK760's listed as high as $8.5k and S&W 76's as low as $10k. It's up to you whether the difference is meaningful and justified. Had a come across a local MK760 for a few thousand less I'd have probably bought that instead.
