The SU-16CA Is a hybrid of the SU-16C and SU-16A rifles, and is legal in California.
The receiver, 16 inch barrel with 1/2-28 threads, bolt carrier, dust cover, sights, and case deflecting operating handle of the C model are combined with the stock of the A model. The SU-16CA will come with 2 10 round magazines that store in the stock just like the A model and has all the same parkerized parts as the C model. Just like the A model the SU-16CA can be folded for storage and it will not fire in the folded position. This allows for it to be purchased in most states that still have an "assault weapons ban".
The model is California legal.
