The discussion of the Alien series of films and the props used in them is the aim, but if it's got Big Bugs and Big Guns, then they are welcome too!

 Post subject: M41a outer casing problem
PostPosted: Thu Apr 22, 2004 7:03 pm 
Hello, I'm Mallow

Spat (www.spatcave.com) suggested this board to me as a possible resource guide.

My question (to whoever can help me) is where I might be able to find a kit containing the main body cover/frame, colapsable stock, magizine footing, barrel shroud, LED countdown circut, and UB grenade launcher muzzel plate that will accomidate a functional Tompson M1A1 reciever, Remington M870 action and additional recoil support bars.

I welcome questions about tecnical nature of my project (so someone can provide me with more specific data)

Thanks
-Exodus

The GNG Pulse Rifle kit is probably your best bet. It has most if not all your requested features. It is available at DenTrinity. Question: by Remington M870 action, do you mean that you have an actual M870 you want to install and have it cycle shells? If that the case, unless you have access to a real steel Spas 12 cage, then I think you're out of luck. Fortunately. the GNG kit has a Grenade launcher section that simulates the shotgun action but you can't load shells.

If the M1A1 has a moving bolt then the GNG kit would also be a good choice, as most of the other kits out there do not accomodate a moving bolt with a locking stock mechanism.

There are more pics of the GNG kit here.

A lot is dependent on your budget, do you plan to have this blank fire, what you have on hand or plan to buy, etc...

A functional Thompson?

I'm pretty sure that anything designed to work with an airsoft gun would fall to bits pretty quickly when firing live or blank rounds.

Also, I think the counter relies on the airsoft battery and trigger mechanism to tell it to count. You'd have to hook up a trigger switch and power source to make the counter function.

When it comes to the GNG kit you're incorrect. While the SD, GEM and Hyperdyne kits rely on the depression of the trigger switch to count the display down, the GNG kit I mentioned on the other hand, uses a light gate (optical sensor) near the mouth of the barrel to actually count the BBs passing through.

FYI, none of the counters currently out there depend upon the airsoft battery itself. They all rely upon a seperate 9 volt battery to power the counter itself.

The term functional needs some clarification here. Does functional mean it fires rounds, or fires blanks, or is deactivated with a moving bolt, or has a scratch built receiver with a moving bolt? If it's either of the latter two, then all the current kits out there should be fine. If by functional you mean it can fire blanks, or actual rounds, then you have two choices: (1) have a shroud made out of metal created either by metal casting or through sheet metal, (2) find a polymer/resin that can handle temperatures of that high magnitude. Regardless, there are lots of questions that should probably be clarified.

I meant that the counter relies on the airsoft battery to spin the motor and activate the relay which starts the counter, not actually power the counter. ;)

Having said that, if that one uses some kinda sensor on the barrel then it's not gonna be much use with an inert real-steel receiver and it's probably not gonna do much better at keeping count of .45ACP bullets!

Thank you uscmCorps, and Hissing Sid

To clear a couple of things up; yes I'm planing on using a real M870 action that will have a four shot capacity, and I am also planning on remilling a Tompson reciever and barrel to use 10mm Auto which matches the bore size of the M41a and allows the shortened 20rd (45acp) magizine to hold 25rds of 10mm.

Thanks again for all the help!

Questions about this GNG kit from Den Trinity, I looked but couldn't find specifics:

Does the counter work? Does it count down from 95 to 0? Is it red or green?

Does the stock slide in and out and lock into position?

Has anyone tried replacing the dummy shotgun shell with a dummy pulse rifle grenade? Is it even remotely possible? I like the look of the kit, but the shotgun shell makes it look lame.

What parts are metal? Someone said the barrel shroud, how about the stock?

Thanks! I'm finally at the point of looking at adding a Pulse Rifle to my collection and have a place that can supply a Thompson and do the conversion, but need the kit!

I think I need to clear up a couple technical issues for you...

This is an impossibility, because when the loading tube and barrel on a real steel (or airsoft for that matter) M870 are cut down, and when you put the spring follower and other parts back in there's only room for 2 rounds, one in the barrel, and one in the magazine tube. You cannot in any way put 4 rounds in there, unless you have access to technology that allows you to bend space/time. :)

You Do realize that the real guns used were .45 caliber, correct? I mean, in the film they do say "10 mm" but reality and fantasy tend to stop mixing after the technicians get the orders to make a film prop.

Somone else here once started building a firing Pulse Rifle, but they ran into issues with getting the outside of the barrel milled so it would fit a barrel vent.

And last but not least, you're going to need authorization from the BATF to even make this kind of item. You'll be ending up with 2 class 3 short barreled weapons that will require appropriate paperwork to be made real. We have a few people here who work for gun shops that can fill you in on the necessary costs of making such a thing.

Thanks for the link to that review, that answered a lot of questions.

One last question though, anyone know of a source in the US for these kits? I hate having something shipped from over seas, I don't trust customs agents at all, I've already had one item stolen by them (note, not seized, not sent back, simply STOLEN) while coming through customs.

Edit:

Never mind, found one, going to order it tomorrow! :D

I'm not aware of any online stores based within the US that carry the kit on its own. Most, if not all, sell the kit as part of a fully assembled piece. Which usually means that they're selling the kit wayyyyy over retail. Best bet is Hong Kong.

Actually, I found Airsoft Extreme is carrying it with plenty in stock. Located in CA I think.
