The first and only fixed magazine compliance kit to make AR-15 rifles and pistols California/NY Legal while using the original mil-spec magazine catch. With MagLatch F.N.G.R. installed your firearm is no longer deemed an "assault weapon" by restrictive states. Our kit installs as easy as the mil-spec magazine release because it is exactly that. We've taken mil-spec parts and modified them rather then redesigning a perfectly good solution. That means no funny arms, milling, or drilling your lower. Our compliant device converts your firearm bypassing assault weapon registration requirements. Perfect for competition shooters who travel to restrictive states or vigilant citizens behind enemy lines. Zombie Apocalypse? Martial Law? Revolution? We're the device for the job. The F.N.G.R. conforms to all requirements of SB 880/AB 1135 and NY Safe Act. Most restrictive states follow the same requirements but be sure to check with your local authority before installing our device.

MagLatch devices always have two modes: free state and ban state. While in ban states a ejection port loader such as the Bear Flag Defense BF-10 is recommended for fastest reloads. When traveling to free states disassemble the action and remove the F.N.G.R. shim from the lower receiver.

Fits on most mil-spec forged AR-15 style firearms and other variations utilizing a standard AR-15 magazine catch. Certain billet AR-15 lowers may require fitting of the F.N.G.R. shim due to smaller recesses in the magazine well.

Don't forget your backup F.N.G.R.'s!

After overwhelming requests to solve the ever growing problem of forgotten magazines, Andrew Bobro of Bobro Engineering, designed the F.N.G.R. to prevent misplacement of your magazine. F.N.G.R. was originally designed to retain your firearm's magazine in the confines of your lower receiver to prevent loss or theft.

MagLatch devices have not been approved by the CA DOJ. This device was designed to conform to the law as written in SB-880/AB 1135, which defines “fixed magazine” to mean 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. Thousands of units have been installed and tested under the law. Multiple authorities have authorized use of our device. Since DOJ refuses to release an opinion letter we are unable to claim it is DOJ approved.
