Did a lot of business with Riley's over the years that I lived in NH, practically next door at Granite Hill.
If you have issues with the help, ask for Ralph. He is the owner and a heck of a good guy. I had issues with his former partner & proceeded to rip him a new one (using socially correct terminology
) in the middle of his store and yes the deal did go my way at the end of that. The partner has since retired.
Old Man Riley who opened the place was a former NRA president and a real good guy and that is who Ralph learned the business from.
If you can't get satisfaction after speaking with Ralph, then write them off.
I work in a gun shop / shooting range in Arizona and C3Shooter has it exactly right, the NICS does NOT ever tell the LGS anything except "Proceed", "Delay" or "Denied".
