Unfortunately, there will be no way to legally argue that you were legally in possession of a 50BMG rifle prior to 1-1-05 if it wasn't registered by 1-1-06. There is no way to make a newly registered AW into a legal 50BMG rifle.

You can email the state a letter and they will reply pretty quickly for a government entity.
My two 50's are both single shot target rifles and are registered as AW and they are listed as 50BMG on the paperwork.

No, they are registered "50BMG rifles" not "AWs". It would be illegal to have registered an AR lower as a 50BMG rifle and then turn it into an AW. In fact, the M82s which were being sold in 2004 with fixed magazines and ended up getting registered as "50BMG rifles" still can't have the "capacity to accept a detachable magazine" today. The owners of those better reregister them as AWs next year or, they could end up loosing their rifles and facing criminal charges.

A registered AW which fires 50 BMG is NOT ".50 BMG rifle", even if they happen to BE rifles which fire 50BMG.
At least that's what 30530 says.

30530. (a) As used in this part, ".50 BMG rifle" means a center
fire rifle that can fire a .50 BMG cartridge and is not already an
assault weapon or a machinegun.

Can folks register a bolt action as an AW for the 2017 new rule and allow for future 50 BMG barrels?

Can folks register a bolt action as an AW for the 2017 new rule and allow for future 50 BMG barrels?

In theory one could. Provided you INTENDED to use the action to make a semi-auto rifle from it. At which point you could register the action as an AW, then later build it into a 50BMG if the semi auto didn't work out.

The way it was explained to me was as such, an AW can have a 50cal element that is added later with no legal issues. So in theory, yes it could work.

There is no possible way for a manually operated rifle to be an AW.

In theory one could. Provided you INTENDED to use the action to make a semi-auto rifle from it.

The action needs to be assembled as a semi-auto centerfire rifle with features before the end of 2016 to be registered in 2017.
