Franklin Armory is showing off their new solution for California AR-15 compliance. Starting this year bullet buttons are no longer an acceptable solution to keep a magazine from being easily replaced and so a number of companies are coming up with ways to keep their AR-15 rifles as close to “stock” as possible while still complying with the law. Franklin Armory probably has the easiest solution on the market with their new magazine.
The trick here are the lips on the back of the magazine. Instead of inserting the magazine from the bottom, the magazine is inserted from the top of the lower receiver and the lops on the back prevent it from moving any further down or ejecting. In this configuration the upper receiver needs to be pivoted up to access the magazine to reload which is annoying enough to make California happy.
The DFM magazines retail for $24.99 on their website.
