As of a couple weeks ago Lee Kay Shooting Center no longer allows any NFA item on the ranges. While rapid fire has never been allowed, machine guns, SBR's and silencers have all been welome at the range. I shoot there about once a month and have used all three at the rifle ranges with no problems for several years. Today when I went to sign in I was told to keep the silencers in the truck.
This all happened when one of the range masters asked to see someones stamp for their .308 silencer. The shooter informed the range master that he had no obligation to provide the paperwork but he would anyway. After further investigation Lee Kay officials decided it would be easier to ban NFA items from the range instead of having to deal with them.
Yet they do not seem to have a policy on people shooting while intoxicated, again.
