Issc MK22

- Start date
When I take people out shooting, it's one of my most popular guns. Especially among people who are beginners. I think they like the looks of it... It's "cooler" than my 10/22. (And it's not just kids who think that - the adults too!)
That being said, I've had problems with mine (it's one of the early ones). I've just done some work on mine to try and improve the reliability (I was getting 2-3 FTFs per mag of 20). If this damn snow ever melts, I hope to try it out in the next week or so and see if I've fixed the problem.
It's a gun I desperately want to like, because it really does look good (I think), but until I get it running better, it's become a love/hate relationship.
Maybe the new ones are more reliable? I've heard rumors that they have "ironed out" the bugs. Maybe someone with a newer one can confirm this.
Theres a few threads on this one already. You'll get a lot of people that will tell you to go SR22 or 10/22 and you'll also get people that tell you its great. If you have a chance to pick one up and shoulder it that would be the best test.
I have one and personally really like it. It did need a bit of work (most semi-autos do) to get it running 100% and it can be picky with ammo too (again, this is not uncommon for semi-auto rimfire). Stay with high velocity for sure. Mine likes federal automatch and CCI minimags. Havent tested anything else with it.
I like that it has the folding stock and is non-restricted. It's got lots of rail space as well for accessories too. There is also a user on here that has been making thread adapters to allow it to take a standard AR muzzlebrake which is handy.
As for what work it needed? Some people have found they need to loctite a bolt or 2 and some have found they need to trim the firing pin return spring. All in all, its a pretty quick and easy fix and you can take care of these issues once you're put some rounds through and need to clean it up.
Ultimately this will depend on what you're planning on using it for. If you're looking for a fun plinker with a tacticool flavor then yes this will likely fit your bill. Best option though is to find one you can shoulder. Compare it to some other tacticool 22s you're looking at and decide for yourself.
On a side not I think the MK22 and SR22 are the only factory tacticool'd rimfires that are non-restricted.

They did fix a lot of the issues. The new stock is more solid with less play than the first gen. The flip up sights were replaced with a spring loaded polymer version and there is plenty of loctite all around. The BCG bolt is also longer which was the main source of light strikes.
Some people have reported that there wasn't loctite on their bcg but the bolts were the proper length.
A good resource for information on the MK22's is the FNForums. They have a lengthy active thread about problems, and fixes. As fchan stated, like other .22 semi autos there are going to be issues. Take your criteria for a rifle, and measure it up with other semi auto .22's. I personally like mine a lot, it's very accurate out of the box (in my experience) and fun to shoot. However, I can not speak about other .22's with any sort of authority, as the MK22 is my first one. Shoulder one, and compare. If you were closer, I would gladly let you take mine for a run.
Mossberg also make an AR style semi auto .22 that's non restricted.

can you please provide some more context to help OP understand?
A lot of these editorial type comments about it sucking with little to no context aren't overly helpful when making a purchasing decision.
It would be useful to know:
-what issues you were facing?
-when you purchased the rifle/which generation? (the latest to hit the shelves have the fixes applied, as with any first generation firearm there are growing pains/kinks that need to be worked out)
-any fixes you tried? (It's been stated about the fixes to common issues, 90% of issues Ive heard of can be remedied with an allen key and loctite)
-did you clean the rifle? (dirty chambers can cushion the casing upon FP impact resulting in a light strike)
-what ammo were you using? (low or standard velocity rounds have been known to be problematic. Furthermore I have had stovepipes due to cheap/poorly seated rounds in a casing.)
All these really can have an affect on the rifles performance much like with any other other rimfire semi-auto.
Also as rootzee mentioned mossberg does make one too, i did forget about that one as well. It does come in significantly cheaper than the MK22 and the SR22 but there is a difference in ruggedness.
I've had two. Both were crap out of the box. After some research and about a half hour of "fixing" it runs like a champ. I shoot CCI blazers mostly, but I also shoot CCI velocitors and quite a bit of Winchester 555 packs. Haven't had a light strike in a long time. I am having some fail to feed issues (with all brands of ammo) but thats the magazines. This weekend I'm going to take them apart, clean and oil them to see if that helps. Bottom line, if you like the look and the feel of it, as i do, buy one. It may need a little work out of the box but once you get it running smoothly you won't regret it. And IMO, there is no difference between "generations". I got one in May 2012, and the other in Jan 2013. They both needed work.
I have one of the "2nd Gen" ones as well. Found after every 5th mag, I need to give the breach a quick cleaning to keep it firing somewhat reliably. Mind you, the only fix I have done so far is stoning the firing pin. I am happy with it, my wife really enjoys shooting it. Just note, if you are looking for spare parts, the dealers can't help, and the distributor and manufacturer don't seem to care about responding to inquiries. YMMV

LOL!
Transporter, nicely done! How do you like the tpod grip? I have been thinking about picking one of those up.
