"I'll say this first, I'm not a regular airsoft player or play against other people, I have been messing around with airsoft guns, mostly springer pistols and low end aegs for 10 years or so. So this was going to be my first high end aeg and I've always like the real Thompson, especially the M1A1 from World War II.
First, out of the box, i did appreciate the weight and the solidity of it. The upper receiver though made from a cheaper, lighter metal doesn't feel cheap, the charging handle has a spring that can be pulled back and released, making a cool sound, but doesn't have any effect on the gun or visa versa (however, relatively easy for those more technical to attach it to the piston for recoil affect, see youtube). The lower receiver is plastic but is thick and durable. The wooden stocks and handle are plastic as well.
The faux wood actually looks good, my only complaint is that there are rather obvious seams where the two pieces are connected, but again, I wouldn't call it "cheap".
The gun itself seams pretty powerful and accurate. However that is comparing it to the low end wal-mart M4's I used to mess around with. I've had it for about a year now, ran around 2000 bb's through it and still seams to be as good as it was out of the box. At closer range, 10ft or so, will go all the way through a pop can, at 30ft will still go in but not come out, at can still hit them at 50ft. I've fired entire 60 round mags through it with no skipping or jamming, and from what I've seen about 400-500 rpm . But like i said I've never messed around with a very high end aeg like a Mauri so I can't say this aeg is great, possibly its actually underpowered, but for a 150 bucks pretty good, especially for someone like me that just likes Thompsons in general. Defiantly a cool toy to have on a shelf but couldn't say if its the choice for a hardcore player.
One last note, this gun is kinda tedious to break down, there are a lot of very small parts that get lost easily, and you need like 4 different wrenches. And I've heard people say they don't like the lever magazine release, but i think its ergonomic, the two selector switches are kinda a pain but come on the gun design is almost 100 years old"
