What do you think of this PCP design concept?

The B.A.M.A.C.H PCP Rifle
Below is totally made up. Just a concept I thought a few hours ago and wanted to share.

The B.A.M.A.C.H PCP Rifle Bolt And Mag Advancing Charging Handle Rifle
The best full gas and spring functioning full auto pcp rifle design is the Hatsan Blitz. Its a very simple an brilliant system to spit pellets full auto using no batteries as other pcp rifles have used in past. However the design has some limitations and drawbacks for its full auto capability. One drawback is that in order to cycle the semi/full auto function some of that precious gas pressure is used to perform that cycling function. It would be more efficient to use a differnt source of power to cycle the bolt. The second limitation is that the power source to advance pellets is within the mag itself. It would be nice to have a cycling power source outside of the mag. Having both of these concepts opens up the possablilites for belt driven mags, high capacity mags, and higher caliber pellets as well as increasing power per shot or increase in shot per fill in both semi and full auto function from a PCP rifle. The BAMACH pcp concept allows these possAbllities.
The B.A.M.A.C.H PCP is a design concept that advances both the bolt and the mag cycling using a single charge for multiple semi auto shots. The charging is done by a side charging handle much like the side charging handle of the AR. The One quick charge pull powers 20 rounds, 2 charge pulls power 40 rounds. The charge is stored with spring power that sits around the barrel. Each shot releases a bit of the spring charge to cycle the bolt and magazine. With this concept it is possible to have both full auto function with belt fed or mag fed pellets or slugs ( sig mpx style ). This design can offer firing of higher caliber pellets with high capacity. Sense the full auto does not rely on the gas pressure as the Blitz does it would also be possible to run a regulator and power adjustments with full auto function on lower pressures that what the Blitz can fire now.
The gun I picture in mind as a BAMACH PCP base model Hatsan Jet 2 PCP. What left of this concept to come to life is the secrete sauce of applying the spring function of the charging handle to power cycle both the belt drivin magazine and the bolt.
What say you?

So basiclly a Garage door like spring to power stuff.

To power cycle the pellets in the mag and to charge the bolt.

Or…you could add pedals, and multiple barrels and you could cycle through the different barrels while simultaneously pumping the bottle up!

That is some way out poop... but I was thinking it should be able to caliber change by swapping barrels and of course mags. And to add to your bottle pumping I was thinking of a device to drop a capsule in with water that would provide enough air pressure to fill the tank. We are not there yet.

Everyone does! I remember a guy telling me about a pipe hooked up to a compressor with a hopper feeding shot into it. I don't know if it would be lethal but the annoyance quotient would be off of the charts.

Piston driven blow back system with gear synced cycling between bolt and mag, in a Hatsan Jet 2 would provide all the same benefits.
A semi / full auto pcp carbine / handgun capable of:

accepting belt fed magazine (picture a hatsan magazine that allows you to run a open pellet belt through it. or maybe even the sig pcp mag concept )
power adjusting in full auto mode
providing lever action style air power / efficiency
tether for added air capacity ( like most air guns )
greater cycling reliability

you could build something useful , like a Gatling Gun with .177 ,.22, .25 , .30 . .45 .50, .72 barrels so you can be sure what your aiming at gets destroyed .

I get your point. I just like to think of how efficient air guns can actually be made as far as air efficiency and cycling reliability. But lever action guns don't have to worry about these things as most people use airguns for simple pest control, hunting or just plinking. I get it.

hope you took that as a joke , but using air to power things that are not projectiles in not efficient, at least to my thinking

I wasn't sure if it were a joke because a little part of me wanders if these ideas should be left from the air gun world. But something overcomes me and I know ideas and thoughts like these are not going to be ignored by all forever. I mean I even forgot to mention adding diesel friendly to this design concept.
But why do you say "things that are not projectiles"? I am thinking pellet and slug projectiles.

 

[beerthief]

"things that are not projectiles" , like cocking or rotating mags , making automatic, just pull the trigger air does the rest .

I think it is an interesting idea. You would only need the charging handle to power as many shots as the magazine size, when you load a new mag you could recharge at that time. There could be number of potential problems/drawbacks. Added weight, added parts and complexity. But new ideas and designs usually have challenges to overcome. Whether it could end up being a working idea or not I certainly don’t know, but I think it is fantastic when people think outside the box and come up with new ideas.

Thanks man, Yes but I think you are referring to the BAMACH concept. I have sense simplified it to a piston driven blow back which should use very minimal amount of air to push the bolt group back for recycling. The bamach used stored spring energy to cycle the gun. But if blow back power can be used without spending a blast of air it would be simpler and more reliable in my opinion. I wonder how much power the Sig CO2 could gain if there blow back system was piston or at least not an open blast of waisted pressure. Also I see this piston driven full auto concept fitting on a Hatsan jet 2 package. If it could work it would sell.
