Question: Who's the manufacturer?
Document: Purchased this gun from another retail outlet... the day it arrived a plastic piece broke off of the magazine. Within two weeks, the spring inside the magazine was broken and the gun is useless. The manufacturer offers a "30 day warranty" but when you try to get a hold of them they refer you back to the seller.
My son has wanted an airsoft gun for years but I would not allow it until he was 13. He was thrilled when he received this airsoft gun for Christmas. This gun did not work the very first time it was used. It jammed and wouldn't shoot. We called the manufacturer and they sent us a new drum magazine(took over a week). The gun still would not work. We called again and they said to ship it them at our cost.
They would not ship us a new gun and only offered to repair the "new" gun I had originally bought. After waiting 2 1/2 weeks, we called, and they said they had not repaired it yet and that it would be 3 weeks before the technician would even be able to look at it! I was very upset and I called for a refund and they refused. I called Amazon and they said they could not do anything because I had shipped the gun to the manufacturer!
this was a very expensive gun , for the high price I expected there to be no problems with the gun , one spin of the mag in the wrong direction made the gun not shoot, after taking the mag apart I discovered a tiny lock washer had fallen off . After putting it back together the gun still has a problem with continious fire , you must spin the mag every 4 to 5 rounds , I would not recommend this type of round high capacity mag it doesnt work well .
this gun was a great buy. it looks amazing, and it dominates in airsoft battles. the only thing i didnt like about it was that the semi automatic function on the gun stopped working after about three weeks. but overall i would definatly recomend this gun.
the Thompson 1928 is an amazing gunPros: great range/accurate: hits hard and fast: battery life last a long time: mag holds lots of BB's: all metal except for handle and stalk: looks awesome all my friends love it and ask were i got it fromCons: well i don't have anything bad to say about it sorry
range, accuracy, fps etc.) The rate of fire is about 700 rpm's (rounds per minute), which isn't bad. It's not the best, but still good.The problem with the magazine: People say it is easily broken. This is true, up until a point. I had some friends over at my house and was showing them the gun. One of my guests turned turned the magazine the wrong way.
pretty damn cool. its heavy like a real gun, but i think that's a good thing. couldn't ask for anything more. now to find an AR of this quality
operating instructions are not very clear and I had to call the manufacture for further details. thank you the Wolfman
it misloads far too often. If you are wanting to fill the drum and blast 400 rounds into your targets, forget it. You have to stop every five to fifteen seconds and wind the drum to pop another round into the "chamber." Even on semi-auto, you will be spending too much time winding your drum. That being said, this gun is great fun. It is very accurate:  I nailed the bullseye on the first shot, at thirty-five feet, using the sights.
