I love this gun. It has a lot of weaver rails, and is very easy to add a few accessories to make it look just like the new H&K MP7... the only thing missing is the telescopic buttstock.... But with a foregrip, a homemade PVC pipe barrel extension, and a few other accessories like a red dot scope and a tac light, it looks just like a HK MP7. Please check out this pic of mine after adding the mentioned accessories onto the weaver rails and making a mock supressor/barrel extension for it; It looks great in this picture at the link here you can see my personalized one, it was very easy to make it look like....

It is easy to convert to full auto of you prefer it over the six round burst. There are many videos on YouTube that show you how to make the full auto conversion on this model, but I prefer to keep it with only the two options of single shot or six round burst. because I am afraid if I change the six round burst to full auto, it will eat up more CO2 cartridges than it already does. The hopper holds 300 bbs and the chamber holds 30 at a time, but you will be changing out the spent CO2 cartridges by the time you shoot up those 300 bbs in six round burst mode.
Be prepared to buy CO2 cartridges by the crate load of you plan to do a lot of shooting. But that says nothing about the gun, it is just the nature of the beast, all CO2 guns.. This one takes them two at a time.
It is VERY accurate, and I was astonished how well it shoots so accurately even in six round burst mode, I was expecting them to spit out all random like, but no, they are almost as accurate as single shot mode, which can hit the bullseye every time at 15 yards with a decent red dot scope or laser sight. Both of which I have added onto the many weaver rails that come stock on the gun. It is by far the best quality and looks for the price.. I would think it should cost twice what it does.
You will be very pleased with the accuracy and also the looks, once you get it accessorized with a few things to clamp onto all those weaver rails, I have got mine looking like a clone of the new HK MP7 and it looks awesome.
