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.


Most Mil-Spec forged lower receivers.

  • Colt
  • Smith & Wesson
  • Daniel Defense
  • Palmetto State Armory
  • FNH
  • Stag Arms
  • Anderson
  • K&M Arms M17S (5.56)

Billet lower receivers:

  • 2A Armament
  • LaRue Tactical
Noreen BBN-223

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.

Kit includes:

  • MagLatch Modified Magazine Catch
  • F.N.G.R. (2)
  • Magazine Catch Spring
  • Magazine Release Button
  • Set Screw
  • Allen Key
  • Installation Instructions

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.

Patent Pending

Manufactured in Goleta, CA

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.

    I really do love it.

    Published by Devon Rosenthal on Jul 25th 2019

    The simplicity of the device is a huge driving point, and it provides in my opinion the most convenient and straight forward compliance solution on the market. Thanks for creating a way to keep so many rifles and pistols, particularly more uncommon models, safely in the hands of their owners without fear of repercussion!

    Awesome cost effective solution

    Published by Cristian Del Rio on Feb 6th 2019

    I'd like to start off by saying that I chose this product because it is the cheapest solution to owning an AR15 in California ( I can rant forever ). The product is extremely easy to install and easy to use. Initially it required some jiggling of the installed magazine for install and removal of the shim. Once I got it fitted it was too easy. I appreciate the price point especially when everything else is twice as much for just the basic compliance piece.

    Works great

    Published by K&M ARMS on Dec 26th 2018

    I had a customer ask if this would work in the K&M ARMS M17S556 Bullpup that we build. So we contacted the company to send us one to see if it would work. Great product and works as advertised in our rifle.
