I own the company and if the contract outlines ars then its all good. Laws surrounding security are really odd when it comes to contract fulfillment.Just curious where you work that allows a privately owned rifle. State licensed security guards are only allowed pistols and shotguns. No rifles of any type per the state. Federal security provides the weapons for those contracts. As to the question yes to a forward assist no matter the environment.
I’m probably going to stick with forward assist just to be on the safe side.I'd personally not carry an AR for life saving duty without one. In the land of super extended charging handles being moved about, all it takes is 1/8 inch for first round to click not bang. Tapping the forward assist assures the gun is locked up ready to shoot. Its not like a handgun where you can physically see the slide not fully forward at a glance, you won't know until you need it. YMMV
