There are two key features I would like to point out.

1. Thumb Screw Pressure Adjustor for different barrel length or suppressor setup. The thumb screw simply increase or decrease the internal blow back gas pressure for the appropriate operation.

2. Composite Piston Dish pushes the bolt carrier group for shell extraction and feeds magazine bullet to the chamber. It completes one operation cycle without the need of buffer tube. This feature helps reduce weight and allows the attachment of folding stock.

3. All key Piston + push arms components are made with heat resistance light weight composite materials.

4.Hopefully the reduction of recoil would be able to achieved by the absent of buffer spring

interesting idea, but it seems to be reinventing the wheel....

Looks needlessly complicated with too many small parts that would be prone to breakage.  

Also, what's the point of the bullet feeding arm?  The BCG is perfectly capable of stripping a round from the magazine without any assistance.

let me know how that works out for you.

If one of the goals of this system is to eliminate the receive extension, that's already been figured out and the solution requires far few parts and the composite piston dish, as it's currently spec'd would result in a bump at the rear of the upper receiver which would get in he way of optics.

May I ask why you keep posting these types of ideas (e.g. the multi-dimensional optic)? What is your career/background?

I absolutely love AR and other tactical rifles but I could not afford one, so I entertain myself with my imagination.

This is only my initial draft conceptual diagram, I have every intention to improve and to simplify the concept.

Its basically a toggle-locking design like the Luger.  They tend to be very sensitive and are easy to break.  I don't imagine a rifle system would work well.

How do you charge it? doesn't it need some sort of spring..? How does the bolt close?

Why not save your money over time and just get a basic A2 model. I'm very sure you can get a relatively decently priced AR that you could afford.

I agree with others too complex and ultimately useless.

Well if your serious about pursuing firearms design then you would be well served by owning some or at least spending some time around. Do have an engineering degree or something similar?

I am from Canada, firearms here are relatively expensive. Beside we both know it would cost a lot more than just the rifle itself. A place to store the rifle, accessories, utilities...etc

Nop. I don't have any engineering background. That could explain my stone-age diagram.

Initial design looks way to complicated.

Owning firearms would be good source of  food for thought if your planning to design better ones than whats out there.

Sincerely, good luck with your endeavors.

While I don't think this particular idea will revolutionize the firearms industry, keep the ideas coming. The only way we improve is with the ideas of dreamers.

A Russian rifle AN-94's operating system appears to be of a similar design.

This design is complex and has too many moving parts to be effective IMHO. Plus, where would you hide this mechanism in the receiver?

This is my initial conceptual diagram. My idea was inspired by pistons internal combustion engines and steam powered locomotion. I was hoping to replace the standard AR reciprocating shell extraction and shell feeding motions with a circular motion induced by the piston dish. I was hoping the circular motion would introduce less recoil than the conventional reciprocating motions.

I could use a dual pistons system where each piston regulates one end of the movement. However this could increase the complexity of my concept when there are already plenty of simpler designs in the market. This is a dead end for me and I need to rethink another completely different concept.

Read them, learn about locking systems tried over the years, they will serve as a great source of information and inspiration.

This needs more small parts...

Think teeny-tiny springs and such.  The ball bearings are good because they respond positively to fine dust, but still... Needs more complexity.

Is there any way you could integrate vacuum tubes into the design?  That would be awesome.

DI is about as simple as it gets and the recoil is negligible in a 5.56mm round.

Keep searching. I agree with getting Chinn's book. It is about as definitive as it gets in weapons design.
