This gun rules. I just got it a few days ago and I've already won a weekend skirmish with it. And, so far, it's racked up about 20 or so kills. It features a full metal tube stock, a full metal upper receiver, a full metal lower receiver, a full metal (rotatable) magwell, a metal handguard, full metal inner and outer barrels, a metal magazine, and welded-on iron sights (a lot of people say that the front sight post is too wide, but when you look down the sights, it's fine). The internals (including the hop-up) are also full metal. This gun is not really for the unfit or weak as it is quite hefty for an SMG. If I were you, I would definitely get this gun, especially if you're a WWII enthusiast like me.
-EVERYTHING is FULL METAL
-Solidly built (nothing jiggles)
-All joints are welded together
-Heavy weighted for a better feel
-High FPS (mine chronographed at an average of 374 FPS)
-Hop-up works GREAT
-EXTREMELY HIGH RATE OF FIRE
The only con is that the magazine only holds 55rds and extra mags are slightly expensive ($20.00).
