“For purposes of this section, ‘fixed magazine’ means an ammunition feeding device contained in, or permanently attached to, a firearm in such a manner that the device cannot be removed without disassembly of the firearm action.“
“…including those weapons with an ammunition feeding device that can be readily removed from the firearm with the use of a tool…“
“A ‘fixed’ magazine, according to interpretations of New York law, is a magazine that cannot be readily detached from the firearm without the use of tools or disassembly of the firearm’s action.“

The Cal Mag Switch was designed after reviewing competitive devices currently on the market and with California and New York laws in mind.
That said, there is no official approval process at any level of government for these types of devices, regardless of what some manufacturers of similar devices try to imply. Moreover, the laws on the books are not always entirely clear or complete, and it is not possible for us to be familiar with the laws in every possible jurisdiction where this device might be used. Thus, buyers of this device – or any other fixed magazine solution – need to make up their own mind regarding suitability and compliance in their jurisdiction. Nevertheless, based on the design and operation of products that have been on the market for years without issue, our considered, personal belief is that our device is complaint as well.
This belief extends to include the notion that installing the Cal Mag Switch on a rifle, and using it properly, shows a good faith effort to comply with the law.
Buyers are cautioned, however, that operating the rifle with the switch in stock mode while in restricted jurisdictions would not be permitted by authorities.

The Cal Mag Switch was developed through intensive research on similar fixed magazine devices on the market that are sold as CA and NY legal.
