Looking to get one of these attached (pin/weld) to a Z5-RS: http://www.investmentgradefirearms.com/igf-us-made-products-navigation-page/mp5-fake-suppressors/

I've sent out a few emails, to ADCO (won't do it) & IGF asking about this service. Anyone know any other shops that can do the work with a semi-quick turnaround & confident enough that the DO NOT drill into the barrel? I'm thinking I will use it as a placeholder, building a rifle until I get the Form 1 filed & back.

I know a few will say to use the brace but I want to be able to try out the various MP5 stock options before I file a F1.

If I were you I'd wait for the stamp
