I love the look and feel of this gun, that's about all the good I can say about it. I took it to the range and shot 3 or 4 different ammo types. I had problems with all of them FTF and light strikes in turn then FTE. I figured maybe it needed a break in. I got a new mag and tried it with CCI and Aguila ammo and all the same problems. I email Buds about the problem they replied with an email address to get in touch with the people who do warranty work for this gun. I called these people and they said the only kind of ammo that will work in this gun is CCI mini mags. I was a little turned off by being told that I could only use one type of ammo, I have never heard of a gun only able to use one type of ammo. They also said that if I sent it to them they could fix the problem. I would have to send them a brand new gun and I would have to pay for the shipping costs. So on top of the price I paid for the rifle now add on $75 for shipping for them to get the gun to run correctly. I think Buds should stop selling this junk of a rifle and get with the supplier to try and work something out for the people that get stuck with a rifle that doesn't work. Help with shipping costs or a discount to buy whatever parts are needed to fix the problem. The insides of this rifle are almost exactly the same as the insides of a GSG-522 and they work fine so what's up with ISSC why cant they get this done right the first time around? Bottom line if you buy this gun you will either end up spending money to get it to run correct or it will become a safe queen and never pulled out of your safe except to look at it once in awhile. DO NOT BUY THIS RIFLE!!! or at least search for the problems with it all over the web before you buy it so you know what your getting yourself into.

I have had this gun for a little over a month now and overall I am very pleased. I get plenty of compliments and questions at the range and this thing is very fun to shoot. My main cons about this gun or at least the one that I received are - you tend to get a good amount of failure to fire or failure to feeds but other reviews tend to say the same thing about the MK22 - my MK22 did not come with the pin for the folding stock (easily fixed with a door pin) - my version also did not come with the pictured flash hider - the release button for the folding stock was broke (also easily fixed) So although the version I received did have it's problems, once easily fixed it is a fun gun to shoot with and I would recommend it but would also advise potential buyers to read through different forums and reviews to make sure you will be good with the potential cons that come with the MK22.
