There is not that much recoil in an AR, but I want to create enough kick so that the shooter can feel it and that it would throw off follow up shots enough that you actually have to know what youre doing when shooting it.
This is what I am working with:
I like this platform because there is a ton of space inside of it as compared to an AR or something, but due to the size and weight, I dont think that a standard blow back/blow open bolt will create enough of a kick. I don't have an aversion to running an outside line, but would like maybe the option of running internal since there is a ton of stock space, but if I cant its no big deal.
The design concept I am leaning toward is an over under style with a steel piston in the lower chamber that is vented with either 1. a solenoid that would actuate the nozzle to load the BB or 2. a solenoid operated poppet valve that is the nozzle. The problem I am seeing is charging time between shots. In practicality, an airsoft sniper usually needs to get off 2-3 shoots in succession, so recharge is an issue.
So any links anyone could provide where people have done some kind of recoil simulation would be greatly appreciated. Thanks!
Edit:
To give more of an idea of the internal space here is another project I was working on before tooling became an issue:
I could run a block all the way back to the back of the top rail and down about 2.5 - 3" into the lower receiver, so like I said, there is a ton of space. That bar is 1x1.5 aluminium stock. The marked parts are where I was going to have to narrow it down to fit it into the the top of the receiver.
