"I've had this gun for a couple or so years, and let me tell you: It is rock solid. The entire body is solid metal (excluding the pistol grip and stock of course). But let me lay it out formally:
Solid construction, can be pinpoint accurate out of box if you can sight it/have an optic for it. Quiet yet audible selector switch. Electric blowback isn't amazing, but a fun feature. Can be adjusted off with an included rod from what I can tell. Full rail system, unlike some 551/552 variants where they lack an optic rail out of box. Perfect for red dots, ACOGs, flip-up sights, foregrips, PEQ boxes, lights, etc. Black paint finish won't come off unless it's sharp metal-on-metal contact.
While it is accurate, the hop-up/barrel length certainly limits it to CQB a good bit. Effective range is 100 feet, maybe tad more. The mag release, while formatted like an M4 as well as the magwell, is further away. It makes it a rather uncomfortable reach for the index finger, even for my lengthy fingers. The magwell does accept M4 mags, however, not the traditional metal/boxier mags, more like slender, polymer mags (kwa, Pmags, G&G, etc.). Iron sights are mediocre, and removal of the front sight should be done with caution as the bolt is pot metal it seems. There's a slight wobble in the handguard. Not loud, but you can feel it. Easy fix with a rail cover to bridge the two top rails. Stock doesn't allow much battery space, but one could replace it with a crane stock. I kept it stock with a 7.4 lipo. Also disassembly is tough, the RIS handguard scratches the paint if slid the wrong way.
Anyways, if you want a CQB rifle that's solid, got heft, accuracy, and unique to boot, it's a worthy buy. I bought it back at $330, and still look at it on my gun wall happy with it. My only recommendation is a crane stock to fit better sized batteries, and a red dot/flip-up sights. Besides that, it is a great gun out of box. "I personally love this gun. It has a very solid and reliable feel. After about 5 days out with it I needed to have the O-rings resealed, but other than that it is a very fun gun to use. The mag release is much further up than the m4 I was previously used to using, and took a little getting used to. It was nice that I didn't have to change mag platforms even.
good rof (with a 7.4 lipo)
great gun overall
has sealing issues (not a terribly expensive fix)
Awful stock "TL;DR: Skip this gun.
The gun was mediocre right up until the stock snapped off.
Proprietary battery (I avoided this problem by using a mag pouch that attaches to the stock to hold a large type battery)
The handgrip is way larger than a M4 and the mag release is much farther as well. Considering the real steel version was designed to offer M4 users a seamless transition from one gun to another, this is a pretty big thing to overlook.
Crappy compression caused the gun to shoot at around 290 fps out of the box.
Proprietary parts all over the place, most of which have to be ordered directly from King Arms.
Very wobbly stock
The shaping of the rail system is such that I couldn't install most accessories without filing them down first.
The stock plate is made of extremely flimsy aluminum. Look around the various forums and you'll see that having the stock plate snap is a VERY common problem.
Like I said, stay away from this thing. Read More Reviews Write a Review
