Bought this gun last year to use as a DMR. Ill start with the construction. When they say "full metal", it isn't literally all metal, as the stock and grip are plastic, but they are very sturdy. The butt plate is metal, however, with a nice locking swivel door to house the battery. I would recommend not slamming the stock against hard objects though, as it is only plastic. The rail system is very impressive, the top weaver rail going from the back of the reciever all the way to about an inch or so from the front sight, giving you PLENTY of room to mount whatever optic suits your play style. I currently use an ACOG style red dot sight and it works like a charm.It also has a few small rails around the front on each side, for bipods, lasers, flashlights, etc. One thing I should point out is that this gun is rather finnicky with magazines, at least mine was. I have a 10 pack of King Arms 5.56 mid cap magazines that feed perfectly in my Elite Force M4, but they do not work at ALL in this gun. I currently use Magpul E-Mags (the 75 round version), and they work just fine. Every hi-cap magazine i've tried has worked as well. This gun is pretty accurate right out of the box, as it has a very long barrel. I would recommend putting in a tighter one if you plan to use it as a DMR. I have an extended tightbore barrel on mine, and the end is covered by a mock suppressor. It gives it a very SR-25 like look.
Great rail system
Excellent as a DMR
Nice and heavy (I also play with an A&K M60 so the weight is not a big deal for me)
Looks intimidating with a mock suppressor
Plastic stock (be careful with it)
Weight (smaller people may have trouble handling it)
