As soon as I get a production version surplus I will send one to the ATF for an offical rulling - they want a production version to eval.
most likly it will considered pre ban only so you have two options
1. Wait till the law sunsets (or gets replace with somthing worse)
2. and/or in the meantime decide what length you want the stock and have us fix it in that posision- If the law sunsets you can send it back to us and we can change out the fixed piece for the real spring and plunger which operates the leaver.
Another option if the law remains is to get a FFL and call the post ban a LE dealer sample.
