Title: Hatsan AT44 (Pneuma) Bullpup - Phoenix (Firehawk)
Post by: unclejack on November 27, 2012, 05:28:00 AM
I made Hatsan AT44 bullpup for hunting rabbits of snow field, the receiver chassis was made from 3mm aluminum and butt cover was from 2mm aluminum and ABS.  Grip is AR15/M16, added thumb-thumb down type safety. The structure is similar to below builders;

Just old general 2D drawing program, from imade designs (just like below) to 2D drawings.

Mid balance is easy holding and aiming.

Fun to shoot in snowing day ! Wood stock does not work in wetty days, only synthetic and aluminum stock stand for wetty condition.

Form of Pistol like maneuverability cabine, so called Bullpup. Since Steyr introduced AUG in 1970’s, many carbine rifle models are used form of bullpup, like FAMAS, Fin2000, FN P90, L85A1, EM-2, … even China introduced QBZ-95 models.

Wow, that is a mean looking airgun! It's good to see people modding the AT44. I am getting pretty interested in that gun as the modding community around it grows.

I have a great respect to aftermarket airgun parts suppliers, especially for stock builders, such as TERYX, LeftyMadrid...
As per my hearing stories, most airgun Stock builders are common people, like you and me, and who like to make stocks, probably the majority are DIY type people who bought some volumed raw material to make several stocks for own use and re-sell, to reduce the cost of own use stock (minimize investment); then, stop making stocks (or got some sort of confidence to continue do so!).
Some builder are eager start own business and success confidence, which will be a major undertaking in their lives. So what happens if the fix cost each stock is 50% and they produce ten (10) bullpup stock kits ($550x10x0.5=$2,750), or twenty (20) FT stocks ($350x20x0.5 =$3,500) in the first run? If only half of them sell, they can manage to eat the loss and still have a life. If they annually produce 500 bullpup kits ($550x500x0.5=$137,500), or 1,000 FT stocks ($350x1000x0.5= $175,000) and can't sell them, they still have to eat the loss and recovery from that would take a long time. It's a risky venture because of super small market (demand-supply).
Thus, the stock business will be some sort of side-business, they must have their main business, such as making tables, chairs… just like machine shop guys are making bike and auto parts besides airgun machined small parts, because CNC and large power machines are relatively expensive and the initial investment became large. In addition, there are no guarantees that everyone who says they want a bullpup will be willing to pony up the cash until they see and hear about what’s to be had for their money. If you were in their position, you might start small and slow as well. The word will get out as soon as the first run is in customer hands. That will be the magic day when their dream comes true, or crumbles in their lap, just wasting time and money.
In a blue collar life, sometimes you have to start from scratch, or don't start at all.
Very risky is my words.

Bipod is Israel made swibel grip-pod.

Its a lot of work to make a bullpup.

My 1077 bullpup was quite a challenge and when I started I was going to make two until I realized how hard it was just to make the one. Now if I had a cnc router or router duplicator that makes it a lot easier but you a very expensive way to go.

To be able to put a price on it is hard.

An easier alternative is to bullpup like a crosman 2240 where you don't have to design a trigger linkage.

If your into rimfire another candidate is the Ruger charger, would make a great easy bullpup

 I do not have machine shop, CNC metal lathe/mill/drill machines, CNC metal machines are at least $7,000.   My power tools are disk sander, table-drill (see below), and jigsaw only, large hand tool is English wheel.  I simply use everyday-technics such as cutting, drilling, filing, sanding, and painting (http://www.harborfreight.com/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/i/m/image_12711.jpg)

Well ya did a great job with the tools you had on hand.

I had a lil cnc desktop machine I sold right before I got into airguns now I regret it.

What 2-d program did you use to draw that up with?

And thanx for the bullpup forum link I signed right up
