Just purchased this beauty, and I'm new to the whole area of model guns. I've tried reading numerous posts on this site and others, but all the terms, different kinds of guns, etc. has gone over my head. I ordered 7mm caps, because every website seemed to say this gun used them, but I am not getting the desired results. I found from this site that I need some glue stuff to keep them in place within the rounds (makes sense since they move around)... but even when I get a successful fire, there is no blowback, and only a little smoke comes out the receiver and the barrel. If anyone can please help out a new guy with what I need, I would greatly appreciate it. I included the picture above to hopefully show the exactly what I am working with. Thanks in advance.

d-solider,

Your det-pin (pin inside a chamber as in your photo) and the cartridges are not for PFC cap.
This is for paper cap (no-longer in production). If you want your tommy to get blow back, need PFC version of det pin and the cartridges. I can get the cartridges, but don't know how easy to get chamber as MGC went out of business.

shaz,

Of course this was not mentioned with the ebay description... thank you for figuring out my problem shazhib, I appreciate it. I'll try to locate a PFC part. Do you know if its as easy as replacing the bolt and firing pin? Or not really so much...?

Hi,

You do not need to replace bolt.
You need to replace a chamber and a pin inside the chamber.

Okay,thanks for the clarification. If anyone knows of any resources where I could acquire the required parts, please post the links. Thanks again.

Hi d-soldier,

Welcome to the forums first of all It's great to have you on board.

As shazhib has informed you, you've got yourself an early version of MGC's Thompson which fired the old open type cartridges loaded with paper caps.
If you are getting smoke out of the barrel you've got yourself a nice example which is sought after these days. All the later type have blocked barrels so a venting one is well worth having.

I have an early version that was relatively easy to convert to fire c.p. type rounds which you'll need now.
Mine had been "done" before I bought it. It had a new MGC zinc bolt, detonator pin and chamber installed and that was it.
I'm not certain the bolt would need replacing unless the original was worn out though. Your bolt may work just fine

Have a good read through the MGC Thompson section the main listing too when you've time. Conversion from Open to c.p. firing is discussed there in more detail.

Keep us informed how you get on please
