I own many airsoft replica guns and they are neally impossible to tell from the real item.

We have used them in play during an indruder type scenario but only within the confines of the property.

I agree that knowing the gun is a replica can detract from the scenario but when used I am sure the brain plays for safe. When I intoduced it even though it was obvious that it would have come from the gun rack there is still the element of are you sure?

I would strongly suggest not carrying or using any gun replica or not in public scenes or in any areas where you may be seen as most fire arm units will react in the way expected even if it is a replica...how are they supposed to know.

Play safe but if used correctly I don't see why not.
