Aren't they based in another state? Is it possible that other state has more restrictive laws concerning possession of NFA items, and they are trying to cover their asses?
I'm totally spitballing here...it would still make sense to at least make customers aware of this policy.
The whole think makes very little sense to me, it seems like it is only going to drive the most educated and enthusiastic gun owners away from their business.
I guess they can afford to **** away a customer like VUPDBlue, and everyone he talks to...
Yeah, this would make sense. If they had established policies based on home state requirements (or maybe some sort of "least common denominator" requirements), I could see them just sticking to "what works" as they expand to other locales.
Not asking does not create liability. There is no positive requirement to ask someone for the stamp to use a range.
Asking for it may reduce or deflect future potential liability.
Plus, there may be a deterrent effect. If someone is thinking of using an ill-gotten NFA item at the range, and finds out the range is going to ask for the stamp, they may go someplace else. Granted, this is a negligible concern, but the chances are a small, but non-zero, number, so it might be worthwhile to have the policy. From the range owner's perspective.
Again, this is just how I see it.
If deterrence of "illegal" weapons is the goal, it would seem to be a more effective policy to notify all customers they're going to check and they reserve the right to inspect all weapons for legality and/or safety before even entering the facility.
