Just finished screwing up a polycarbonate 80% lower.
This company has a unique method of constructing without a jig.
If you want their name, PM me; I don't want to bad mouth them since I am not a machinist.
Sounded great in theory.
Ended up milling through the fire control side towards the bottom of the pocket. It might have been chatter but it just exposes the danger of a home-built poly lower.
I have a decent ghetto home shop but you really need to have at least a solid jig. Not a home-built jig, but a machined one from the MFR. I took time and used proper equipment, not a hammer and chisel.
I'm also a bit concerned about the thickness of the fire control pocket walls. It's ok if it's aluminum but if poly, then it should be 2x as thick.
If this belongs in the gun-smithing discussion, please feel free to move it.
I'm not in a good mood now but I need to get back up on the horse and try an 80% aluminum billet and find a build party.
