piston bolt system.....an idea.

update....
OK, i solved a few problems that were found in the drawing.

I realize I cant get rid of every single spring in a gun because I still need the trigger spring.

I need help on where to put the firing pin.

should I make it a 2 piece pin or put the pin at an upward angle? Like 10 degrees or so.

thank you for your help and this is an ongoing project...
These are very nice designs, are you thinking of using torsion spring for storing energy so that the back wheel could complete the reciprocating motion?

but how would you stop it?

Exactly.

How do you ensure that the bolt doesn't keep reciprocating and wind up out of battery? In other words, what stops the thing from free wheeling?

Also, can you explain why you think it's worthwhile to replace most of the springs in a firearm? What is the requirement or unmet need this design addresses? If it's just an intellectual exercise, fine. But, to an engineer and a generally pretty pragmatic person, it seems that you have removed the simplest, cheapest and most reliable part of the firearm and replaced it with a toggle system that will need even more complexity designed into it to ever make it work.

the idea more or less started as an intellectual design and started with no springs. then i saw that I couldn't because I need a trigger spring.



Here's what I perceive in this design.

less perceived recoil as its directed down when the shot is fired.

No buffer spring like that of an AR-15.

might be less weight.

might increase rate of fire. like that of auto or bump fire.
 
why would it recoil downward?

I believe it would recoil downward because of were the center pin is on the rotation arm. It is located higher than the connecting rod for the carrier group and the idea is to make the armature to swing in a downward force. albeit this is only a small amount of time in the action,i think it would prove critical..

I believe it does help.

For example, one could design a gun that was electrically operated and fired (either by electronic ignition or by a solenoid firing pin) but then you would need all sorts of extra logistical requirements for no real improvement.

Remington EtroniX was an electrically fired rifle from the 1960's-1970's. Very well reviewed but never caught on.

Currently, there is at least one company (RMFTC) that still manufactures rifles with electronic firing systems.
