Try shooting CCI mini mags or a better non-bulk ammo through it. Some 22lr's are just picky as hell about what they eat.

 

I've been experiencing the same issue.

I field stripped my M-22 right out of the box (I always like to see how things are meant to work on a new gun). Cleaned it up, tightned all the screws, and lubed her up.

Range trip one:
200 of Winchester 40-grain Wildcat (lead)
200 rounds of bulk Winchester Western 36-grain (copper hollows)

Every mag resulted in *several* fail-to-eject, fail-to-feed issues each.

I purchased a pair of additional mags (to rule out a defect with the included factory mag). Cleaned, lubed, and went thru the weapon a second time to tightned everything down.

Range trip two:
300 rounds of CCI 40 grain Mini-Mag (copper coated)
200 of Winchester 40-grain Wildcat (lead)

I did actually get two mags of CCI to run thru without issue. The rest all resulted in *several* fail-to-eject, fail-to-feed issues each.

I want so badly for this gun to behave. It's a real hoot to shoot and I love everything else about it. Both trips to the range, every shooter on the line came over and told me that they like it (usually as I was clearing jammed shells out of it).

I'm sort of at a loss here. I don't know what to try next. I've cleaned it, I've oiled it, I've replaced the mags, and I've tried various ammo.

 

I have an mk22 also. Mine would missfire every time I took it out to shoot it. I counted before 40 shots out of three mags missfired. Now the company is out of business and I'm stuck with a piece of crap.. I dropped it off at a gun smith 5 months ago n he can't figure it out either

 

There could be an issue with the ammo.

Also the chamber. European CIP dimensions and American ANSI are different (that is why Stingers have that warning on the CCI website.)

I have a .22lr semi-auto that call for high velociy ammo only. Federal standard .22lr round nose will not provide enough energy to function the slide (it's a pistol).

Could be the mag. New owners of some firearms load the mag incorrectly and spread the lips (leads to misalignment).

 

Never owned one, but I've heard endless hurry stories.

 

I have used 5 difpin ferent types of ammo.the firing spring sounds really weak

 

Msr mk22

man this is dicouraging to read i just got one of these for my son for X-mas and have the same issues. Now i guess i know why they have no website or do not answer their phone. I bought it at Dunhams sports i am going to run it back there and see if they will do anything.

 

I found the contact info

 

They switched dealers in the USA so this is why I was having problems. The main website was www.issc.aus and they pointed me in the right direction

 

Here's what you need to know about mag adjustment. Also called "Tuning the magazine".
Fortunately, the rules for .22lr's are pretty much universal...works on any metal .22lr mag.

Didn't feel like paying for shipping to Colorado. So I looked into it my self. Took butt stock off and there was a bolt that I had tightened before had worked its self loose. Put some thread lock on it and shot 60 rounds thru it. Worked amazing gonna go thru and do all the screws on gun with the lock tite

 

Hey guys. The problem lies with the magazines. I have one mag fires flawlessly and one that stops the show. The bad mag stops the gun from detonating rounds that feed. Good mag vs bad mag

 

Please don't bring back to life threads that no body has looked at since 2012. Thanks!!

 

The gun is a POS no matter what ammo or condition can't get 10 rounds in a row

 

We agree. Have agreed for some time. 10 yr old zombie thread.
