Pump milling "conflicts"

[daemon512]

Would having a rail and/or body milled for a pump handle prevent one from using that rail/body for a semi?

My uneducated guess would be that it doesn't matter if its milled, because if it were going to leak air on semi with the milling, it would also leak the same air as a pump. I just want to know that I'm correct in my assumptions.

Also, as far as converting a mag to a pump mag, parts needed are:
milled body
milled rail
pump kit (considering rainman, if that makes the parts list different)

Am I missing anything?

Thank you in advance!

It does not affect it at all.

The screw for holding the pump kit on with a vert asa needs to be a little longer, if the kit doesn't come with it, that is all you would need.

Pump milling a body and rail does not effect any thing for it running semiauto. It can be changed back and forth between games if you want too. All you have to do is remove the wave spring and replace it with the blue bumper and maybe the bolt main spring. Some times pump mags need a used weaker main bolt spring so they don't over power the wave spring. You don't even have to take the pump assembly off if you don't want to.
