||I'vr had this for about a month. I haven't used it in commp yet, but I really like it. Impressive rate of fire, nice weight (it is pretty heavy despite being a composite body) and compact enought for CQB. The folding stock is solid. I have seen an extendable stock out there. I haven't decided if I am going to get it or not. This gun makes a great backup for my sniper rifle. It is small enough to carry along and gives me a lot more firepower than a pistol sidearm, when the OPFOR gets too close.
COOLNESS FACTOR: the left side has a square STICKER (yes it is a sticker) that says "G36C Cal. 6mm BB." . This was put onto tthe gun for import reasons. IF you peel this sticker off, then underneath it you will find - MOLDED INTO THE BODY -
AWESOME! This gun was licensed by H&K. It is authentic! Get this gun!
I added an Aimpoint scope, single point sling and a verticle foregrip. The mags do lock together. I would recommend not locking more than two together at a time as it gets a bit off-balance (i tried four heh-heh - looks real goofy too). If you have your stock in the folded position then you can not have an extra magazine attached to the right side of the mag (in the well). This interaction can slow down reloads if you are not careful.
The only real problem I have is this: installing the battery inside the handguard is very difficult (depending on the battery you use). If you make sure that the battery is charged up fully before you start the day, then t really isn't much of a problem.
