Does anyone know of Select Fire LLC. or know anything about them, located in New Haven Michigan? They make 80% Ruger 10-22 receivers for 22 Magnum
I Have been trying to contact the company for the past couple of weeks for a replacement receiver. Had a customer bring in one that had been "worked" on and it is now a 40% receiver, he would like the gun finished correctly and serial numbered.

I guess that from the lack of a response there is no use to pursue the project. Just list it as another victim of the infamous Dremel tool gunsmithing, and the loss of a $300 receiver.
