Hi,
I'm looking to use an airsoft spring-powered gun to shoot 43cal paintballs (11mm, ~0.7g). I have the means of machining some parts (barrel + hopper mechanism), but wouldn't want them to be too complicated. We also don't need much range and don't need the typical 300-400fps speeds. Likely ~100fps would be sufficient.
Some of my questions:
1. Would this be a reasonable modification and would there be enough power in a typical airsoft gun to propel a paintball of the above specs?
2. What are the strongest springs that can be put into a typical airsoft gun, and would that significantly increase the power?
3. How difficult would it be to manufacture a custom barrel (11mm diameter) and have that work with a typical airsoft upper gearbox? I.e. what's important to ensure the ball gets propelled correctly?
4. Has anyone ever heard of anyone doing something similar, I.e. using a spring-powered gun for shooting paintballs?
I don't know much about airsoft or paintball to begin with, so if there's any more information that would be helpful to answer these questions, please let me know.
Here are some of the gearboxes I was looking at for reference:
Lonex 8mm Enhanced Bearing AEG Gearbox Ver.3
ICS M4 Bore Up Complete Upper Gearbox for ICS M4
D Boy OEM Complete AK v3 Gearbox
CYMA Complete Version 3 AK Full Metal Gearbox w/ High Torque Motor
If there are any other sites to be looking at for gearboxes, please let me know.
Thanks!
