Updating of this project, in this case, the LB VI, (lansa bolillas 6). :) LB VI.JPG This prototype is the one that I recently built, which has several important simplifications with respect to the previous one, the first one. Shoots 5X, .25 caliber steel bbs. The loading in the chamber of the ammuni...

Sistema carga de munición accionado por gases, diagrama, (1).gif The problem with the automatic loading of balls is that the spring of the tube that houses the ammunition does not survive more than two or three shots because when it opens, the pressure of the explosion expels the bb`s towards the s...

This is a project called "Armadas 1500 II". It is a weapon that works with an integrated air pump, it is a single shot, hybrid that precompresses at 8X - 10X. The firing barrel is with 12 microgrooves, caliber .25 and fires common pellets. The inverted bolt is made of 1045 steel, the combustion cham...

Playing with a syringe, a small spring a 5/2 and a bb of 6mm, plus a couple of hours in the afternoon. The result is not impressive but yes, very fun to do and shoot. Shoot with 80 psi :bounce:

It is a common valve, of which they have for one side the two escapes and the supply of compressed air, and for the opposite side, the two exits. Too bad that support low pressure, up to 120 psi, but it is enough for this application. I need an exterior fairing with the look of a modern weapon, made...

It was more or less like that, like in the drawing.

Thank you so much guys!

Very clean work, nice "proper" evolution after all that prototyping... I like the markings too, although perhaps it's more of a Fuerza Aerea (+Butanea) Argentina sort of equipment :D Hi Jack!! Oh yes, I'm going to change the brand as you suggest :) . Thank you for viewing my work. A greeting for you!

Speaking of this weapon, this is version "2". The number "1", it is valveless... it does not have any valve. I am trying to seal the chamber directly with the pellet in the barrel. The pellet is "prepared", it has a bit of spelling corrector to increase the seal, (it's perfect), and increase the fri...

The system of this rifle is very creative. I like the idea because it comes out of the conceptual "box" and is repeated all the time. There is always a different way to do the same with its pros and cons for sure. Nice acquisition! :) Adapting it to pcp would improve it substantially, and it will in...

It looks very good, I like it.. Good work!

Adapting this weapon to shoot with rupture disk. It gave me more power and regularity in the shots. I love plain old bursting records... I am using aluminized paper. I'm using two layers, which work fine for 9X of precompression that the hybrid has. The face that is made of paper itself is faced and...

The "cartridges" that includes the rupture disk, seal o'ring and the pellet is as in the drawing. In case of planning a repeating or semi-automatic weapon, with an ammunition magazine, it is necessary to build many.

The "lost gas" method is what I use for my air pump guns and it works perfectly fine. Yes, it is true that it wastes a little gas but it makes everything more practical and faster to refuel. The trade-in is a practical thing for a little more butane in the process. Without hesitation, I accept the "...
