Tech Questions / Low FPS build
« on: June 02, 2016, 01:09:42 PM »
So guys I've come into an odd question and yes I can figure this out via trial and error but I figured I'd throw out a question and see if this has ever crossed anyone's mind as well as maybe save me some time etc.
So my son is very young just turned 4, but he's got an interest in airsoft. Now I'm not planning on getting him out playing anytime soon and shooting will be done with me there hands on the gun. But we've been shooting with my guns for the last year off and on and he always takes an interest when I'm hosting a game here.
So I got to thinking about building him a gun, originally it was buying a gun but I quickly went off that. I had planned to buy him a "boys" series gun like the old TM's. But those are not very durable and quite fragile. So I started thinking about building something sized more to him like an M733 or there about but lightweight. Since normally I could just say "here use my stubby M4" but all of my builds are heavy full metal setups and they would be too heavy. So I started thinking about taking a bunch of parts I've got around and building a light weight low FPS build. IE my goal FPS is somewhere between 150-200fps way under what would be considered a normal build. The reason is safety but also making it hurt less at this point. Now using standard parts I can upgrade the spring over time and get it to a level he can actually use it in a game once he's older. And doing it this way I can just change things as needed and it's not a waste as a cheap boys type of gun would be.
So I'm planning on building out a small M4 platform with plastic body likely, more less the lightest body parts I've got around likely front wired with a normal set of handguards for a battery. Then likely take a stock spring and cut it down, do full compression and shimming work like normal. Then likely a stock bucking and a simple barrel setup.
But then that's the question FPS, since my goal is so low has anyone figured out a means to reliably get that low of FPS. I mean I'm shooting for approximately AEP velocity which I know can't be a common thing since I've never thought to do it till now;) I could drop the FPS via compression, but I don't honestly trust that things wouldn't change or swell and all of a sudden it's shooting much hotter than anticipated. So I think doing it via the spring would give a more stable end result.
So I'm curious maybe someone has built out a super low FPS build for very close CQB or something of the like, if so I'd love to hear any tips you have etc. Otherwise I'll just plan on tossing it together based on my plan and post the results once I get it all done. This isn't a quick project since of course my son doesn't "need" this gun anytime soon. We're not to that stage, so it's more of a background project, might even end up being a Christmas present this year depending on time scale when I get around to building it.
Take care!
