I had bought this gun with a G&G 9.6 nunchuck battery and a Tenergy Smart Charger on April 26th...
All I can say is that it really is good!
The external quality of this gun is superb and it feels sturdy and strong. It is also ambidextrous, which means it will feel comfortable in the hands of lefty shooters and righty shooters. From what I know about internals (which is little to none), it seems to perform nicely.
I have heard that because Magpul PTS guns are made by ARES, that the gearbox shells break easily. I don't have that issue, yet I have not truly put it to the test yet, due to the fact I cannot find anyone to airsoft or go to an airsoft field with at the moment. Other than this, it seems to be nicely made. Airsoft GI is great thanks to their discounts and I got mine at $450!
I've shot over 400 rounds with it and it seems to handle well so far, it also shoots at a ridiculous rate of fire! I do intend to buying some lubricant and silicon spray soon, since I am a newby at all this still, I am going to keep it maintained.
The magazine given seems sturdy as well. Most cry over this, but I'm not finding an issue at all.
~Great external quality
~Ambidextrous features (via: the safety switches, charging handle, and magazine release)
~ Seems to be pretty well-built internally
~ Great rate of fire
~Only one Con: THE COST.
But other than that, if you can get the 20.5% discount on it, it will bring down the price greatly. Though, hopefully nothing will happen to it since if it does, I will seriously get pissed. Lol. Anyways, that's it.
