Nice design.
I have the Crosman 2250 which has the bolt/loading on the opposite side. Do you know if i simply mirror your model parts to print them if they will work? Are the basic dimensions the same?

It is the same yes, check here: https://www.tapatalk.com/groups/yellow/crosman-2240-and-2250-confusion-t152428.html

You can easily mirror all parts with your printing program, but i can do it for you if you want. Good luck. :)

Yes just tried it with Cura.
That's a great help thank you, i'll have a crack at printing it later!

Tx, print it with high resolution and 100%

I asked to kralarms factory, for spring... and they turn to me positive... i get afew spring from factory, for kralarms original magazine... and i made redesigned for spring... now it is working very stable:)

I added a kral index magazine, may be it could give us a different idea..


I have a some problem with my printer, i fix it, yet.. the Numbers hole is doesnt seen, but its not a problem.. it is working very good... :) could we 22mm rail on the breech?maybe we can mount scope with high foot

I am adding a 22mm rail breech now, good idea. And the numpers doesnt show for me to, the printer cannot print
so small text. I am thinking about a bigger magazine, maybe 20 pellets. What do you think?

could you add a 11mm rail model please, if it is not too difficult?

Done, if i made it correct.

Good jop, if it is alittle more thick and maybe we can add after the magazine..

first of all, thank you very much for ask to my idea, you are soo kindly.. brench is look like more artistic and usefull, now... :)

it is very crazy, 20 pellets idea :) Actually for us 5 or 6 pellets are enough... it is may be a little more small and like a revolver.....

Our goal is to move the town, you can enter the case, everyone can move comfortably..

for example, look like this at44 magazine, there are an oring, for hold the pellets together.. what do you think? is it possible ?

Smart. Well it is maybe possible, but how to index the drum? It need a spring i think, and some way to
every pellet.

maybe we need a few spring, somebody maked ZigZag revolver... we can do similar mechinism, but we dont have any area in under,i think we can do left or right sight mechanizm

we need to aim well, if we miss too bad heard :D :D

I shoot black powder revolvers, so i have seen that kind of weapon before. I have a antique Colt and a Remington, both cal 44.

I check that up, i have seen one at Grabcad. I also thinking of some side loading, like a M60 machine gun or similar, but with the pellets on som kind of a rail. Hard to explain.

i understood, but it takes more space if we use pellets rail... the more portable the more useful.. then everyone wants to get or make it.....want to carry at the waist, like in the picture :)

you're just a little bit smaller than the hole? don't let the bullets fall down when moving the magazine

I changed the cover, you can download it now.

No problem i think, it is covered by the breech when the magazine is mounted.
I made that on purpose, for easyer loading. Othervise it is easy for the pellet to fall thru the
loading hole while loading. But i add a extra cover just in case, thanks for your suggestions, that is progress.. :)

this is great :) do you have any video, how it is work?

Nope, but maybe i make one. :)

i did magazine, and i am trying to find a spring, it is look like very nice.. only the cover needs a hole for numerator. :)

Well, it is made for a rubber band, a short one. Check the picture. Othervise, a spiral spring from a small tape measure would work.
The small cheap ones that only measure about a meter. The numbers dont show up after printing, not for me anyway. But i can add a cower with a hole if you want that. I got a loading video to now by the way.

i saw video, this is Perfect working, i Love this project :)

whats the updated files? is there a changelog

It is the final design, i came up with a good idea on the breech, so i had to change it.
Sorry about that. :=

no probs dude thanks for sharing

I found some flaws on the breech, i have fixed that now.
It is fixed now, hope you did not printed it already. :)
