"I havenít used the Thompson yet, BUT I thought Iíd leave my first impressions here. First and foremost, the Thompson came in a styrofoam box that was wrapped in plastic. While I donít like styrofoam, the fact that it was wrapped in plastic is awesome! When the box came in it rained that day and the whole thing was soaked, but everything inside the plastic wrap was dry as a bone. So if it rains a lot where you are, rest assured your rifle will be safe. Next, being full metal, it has some weight to it, but I like that. It adds realism to it. It came with a sling thatís super cheap but better than nothing. Iím gonna get a new one soon. Came with an 8.4v 1100mAh battery that Iím gonna keep as a backup battery just in case the one I have dies or fails. Throw away the trickle charger and buy a smart charger. The mag that came with this rifle is a 380rd hicap mag thatís also metal. Iíll be playing airsoft soon so after my first game Iíll post another review about the performance.

"If you're just getting into airsoft or looking to pick this gun up, do it without a question. This gun, although it is a primitive machine, is amazing. First of all it's the only Airsoft gun I've bought out of the box is super accurate. Secondly, the mags (King Arms mid-cap magazines) are super inexpensive so you can have a buy a ton and if they break, oh well they were $11 and you can get another. Nothing hurt! I would buy this gun again in a heartbeat.

"Probably one of the best values on the market. I have owned this gun for 8 years of heavy use and can say it is the single best performing gun that I have ever owned. I have had a variety of guns over the years and while many of them require tinkering to get to work right this one just needs a bit of wear. Out of the box it has a bit of an over hop problem, but once that bucking wears in expect near sniper level accuracy and range. The range is not that of an hpa rifle, but it is above average as far as aegs and tends to be very consistant. Now what stands out about this gun is its reliability. i have had this gun break once over the last 8 years 6 years after i bought it with heavy use. over the years like any gun you will notice that the spring will eventually wear down and over 8 years of use it has gone from 400 to around 320 and despite the drop in fps it still has about 90% of the original range and can still out range most guns on the field (however i can now use it at point blank range so i will not be replacing the spring). The only bad thing about this gun is the lack of a rail system and the 8.4v battery it comes with as it works best with a 9.6 (8.4v battery is to simulate the original guns rate of fire so highly recommend a 9.6). as far as this gun goes it just works well and i would highly recommend it.


1. good fps
2. excellent reliability (went 6 years with only needing to replace 1 part)
3. excellent accuracy
4. good quality parts

1. creaky plastic grip (stock and fore grip are fine)
2. no rails (it has good enough accuracy to be a good dmr)
3. too much hop-up out of the box (counteract with heavy bbs until it wears down)
