What can I say, this thing rocks! I have had mine for over a year, and there hasn't been too much to deal with concerning cons. The iron sights may not look the greatest, but they're better than you may think, meaning that unless you REALLY want a sight, there shouldn't be a need for one. I use 0.30 BBs, and this thing knows where to go, and goes where you want it to go for about 100-120(abs MAX) feet. The best thing I like about this isn't the 40 round mag, not the 290 RPS, not the flip-up iron sights (which I said are better than you think), nor the ability to go from a pistol, to a PDW, to an SMG. It's actually the sound this thing makes.
This is the kind of gun that scares the crap out of players when they hear it, especially if you are on the receiving end of this mini-monster. The only other gun I've heard louder than this, besides those Polarstar guns, is the KWA MP9, but that already has an amplifier. Put an amplifier on one of these guns and you have a really tough to not hear it kind of gun. This thing scares teammates and opponents alike as is, and it sure is fun to have an enemy get close to you, and then you just hit him from behind or close by. I could go on for a while longer about how much of a BA gun this is, but I guess I should address some issues with this.
First off, this isn't a gun meant for running as a primary (which I, a college saving student, have to deal with it as). This will get you 100 feet on average with 0.30 BBs,and even then that's with full gas, which is another problem: this thing eats gas like a cow eats grass. You'll probably get 2 mags worth of shots max. I'd stay away from full-auto as it has only 40 shots, but also, because the gas sometimes comes out a little, even after you've stopped firing (if you can hear it spewing the gas, change mags before firing again or you'll be out of gas for your next encounter). Ignore what the guy below me said about parts being easy to find, that's not entirely true. Sure online is easy, but if you need the parts for your match next week with friends, then you'll have trouble. M4, AK47, and M16 parts are what you'll find in a store, but MP7 is where everything is online and expensive. Want a suppressor/silencer? Too bad, because even online those accessories are hard to find in stock. The cheapest one I could find for the [KWA] MP7 was $50.00, and even then it had that shiny look for the plastic suppressor (stands out a lot on a matte finished gun). Don't get me started on internals, that's an internal struggle unless you want to go to KWA's site.
Anyways, I do hope the extra long paragraph about its troubles doesn't take you away from the fact that this gun is amazing in terms of showing that bigger isn't better and that even the little guys can make a big scare. I haven't had to look for replacement pieces, as KWA really holds up to the reputation the airsoft community gives them, but that part about being hard-to-get isn't something to brush off. Hop-up adjustment tool can be substituted for an Allen-wrench if you don't want to carry around more than your multitool (which is essential to have when using a GBB). Remember to lubricate it after long periods of use asap, and to fire it about once (literally 1-2 shots) a month to keep the parts from getting comfortable where they are. The guy below, though I criticized him earlier, made some other pointers you should be aware of (because I'm too lazy to reread and copy his story). One of the videos also mentions that using EF green gas is best, which I'd agree. Other than the green gas part, I'd be careful with other things the videos mention or do, such as going underwater with the gun.
Now I've typed so much, so sorry. I'll give it my recommendation as one of the best guns for intimidation, one of the better secondary that isn't a pistol (although it can with a pistol all folded up and/or with a mid-cap mag), and one of the best guns for airsoft players looking to lead the charge in a match. Last thing (I promise), but since it is scary loud I don't recommend staying with people who don't want their positions given away, as hearing this will make both sides probably look in its direction for the first couple rounds they hear it. Use this to draw them towards you and away from others, or to confuse the other team by running apart from the main group.
