They do not work with Stock Magazine base plates. They should work with some Magwell compatible base plate extensions. But we have not checked all brands/companies. They do NOT work with the New style TTI Extensions.
They are designed to work with our +1 Mag Extensions. We are working on +5 Extensions.
Made in the USA
