I have a idea for a FN FAL setup. As soonest I get the m305b ill take it apart and start working on it.
If it works out, and my test results match the required quality, ill send it out to a few trusted m14 experts for testing. I can probably make 20-30 kits. If anyone would be interested in one, like the FN FAL or something that can be adjusted on the go, no tools, just a nob, turn it left or right and adjust the gas let me know. If I do end up making them, they will be CNC, and made out of matching grade material to account for the heat expansion. Cost would be $100-150.
Careful you don't go and get all of our M14's banned
would be a very neat Mod. keep us posted please.
