Ok, you got my attention. Me like that rifle lots.
So it appears that we should be able to purchase a JP CTR-02 rifle either without the pistol grip or with a pinned mag. Probably without the pistol grip would be better/easier so we're following along the same terms as a Robinson M96. Then we could treat it like a CaliFAL.
I'm going to need to save my pennies and talk to my FFL.
