"Cut to the chase, it's not a bad starter for the TW platform. I bought mine second hand, so there were some problems that weren't common with new ones. But I'm gonna address some problems that I see most come with. One big issue with mine was buffer tube shimming. I received the gun, and the cylinder was able to move about half an inch inside the receiver. I had to remove the buffer tube cap, twist the buffer tube at least once and remove one or two of the metal shims. That fixed the problem and wasn't too hard to do. As long as you don't cut your wires (there's a lot) you'll be fine.
Another problem is the wiring. The wiring to where the battery connects is pretty crappy, it bends and gets pinched easily. It also comes with a LARGE type tamiya out of the box, and the wiring is pretty long as well.
Lastly, a big problem are the cylinders. The one I use likes to loosen the nozzle after 50 or so shots, not hard to fix, just open the receivers and pull the cylinder out, then tighten the nozzle until there's no gap. But make sure it DOES NOT get shot into your hopup. Mine did this, the nozzle lodged into the hopup, forcing me to use an unjamming rod to push it out and reattach. It's probably worth it to buy a systema hopup and cylinders.
After these fixes, it performs great. Just don't bother using anything lower than an 11.1v on it. It's a great way to get started into the TW platform without breaking the bank.
Mags are SUPER cheap compared to systema
Parts are generally cheaper
Can't usually mix systema parts with stock A&K ones
A&K hopup isn't compatible with systema cylinders, vise versa
Problems stated above.

All in all, good "starter" gun. Don't get if you don't like to maintain your gun a lot.

"I picked this gun up when its 199 and i think its a good deal
first impression
this gun looks cheap, out the box the hand guard looks cheap, the stock looks cheap,the body looks cheap, but its really solid. Outer barrel is steel i love it. The grip is sorta uncomfortable and slim nut after remove the finger grove everything feels fine.
After one day of use
First time i shoot this, the gun wont feed with valken bbs and the bb will break in the barrel or drop to the ground after 1feet. So i tried some elite force .32, the gun works flawlessly. I cut about 3 loops of the spring and the gun still shoots 410, which is surprisingly high. The gun will not work on 9.6 unless you cut the spring. So if you want keep the spring for a high fps, do pick up some lipos. Gear box is cnced and its surprisingly good. Hop up is really strong and the range is really good for a stock gun that is $200. Rof isnt high but acceptable, trigger response is good, it also have a mosfet in it. But there is one thing that annoy me, the magazine will only fit in around 80 even it suopose to fit 120. The spring will jam in every turn and causing feeding problem, so tr to lube the mag before you go to the field. And a qucok fix that might not work is take the mag out and hit it on the gun hard, that might shake the spring back to normal. So pick some extral mags before you field with this gun. The follower will fall out so considering buying some MAG replacement.

So if you want a cheap ptw to start with and uograde it, get this

"absolutely loved this gun! Great right out of the box. It had the most flat trajectory i have every seen and has a great fps and rate of fire for playing in the woods. Only problems are that they selector switch is rough after some use and the cylinder broke after a month due to factory cross threading. Probably only my problem though. I just bought a new cylinder because it is totaly worth it.
Pros- Great fps, interchangeable cylinder for fast fps swaps, realistic weight, ABSOLUTELY AMAZING TRIGGER RESPONSE, shooting cut off when out of ammo, mags are only $15 (they are really sturdy mags), 99% systema compatible, exterior build sturdy, and the flattest hopup trajectory out there (even more than any sniper i've ever seen.
Cons- Selector switch degrades quickly (still usable but not great), cylinders are made with questionable quality (again, I don't know if this is a just mine problem or not), and does not take other m4 mags (but for a good reason though)
Overall- I would recomend this gun to intermediate to advanced players, but not for Novices, Due to the specific parts associated with this gun.
