With MagLatch is installed and used properly your firearm is no longer deemed an "assault weapon" in 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 nearly perfect platform. That means no funny arms, milling, or drilling your lower. When utilized properly our compliant device converts your firearm to fixed magazine bypassing assault weapon registration requirements. When used properly 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.

Use of a M3 PMAG 10 round magazine is recommended in conjunction of our fixed magazine device.

Regardless of type, fitting of the F.N.G.R. shim may be required due to variations to the recess of the magazine well.


  • IN A BAN STATE: Insert magazine of 10 rounds or less. Insert F.N.G.R. shim.
  • IN A FREE STATE: Disassemble Upper and lower. Remove F.N.G.R. shim. Use rifle as intended where legal to do so.


An ejection port loader such as the Bear Flag Defense BF-10 is recommended for fastest reloads.

Kit includes:

  • MagLatch Modified Magazine Catch
  • F.N.G.R. (Type 0, 0F, 1, 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

MagLatch devices have not been approved by the 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.

    Easy to incorporate.

    Simple to use and attach to your AR. I have to use these as I’m in a blue state. But they are simple to attach and if you want to change out the matches for something more fitting to your build it’s simple. If you want to ensure your mag well isn’t grinding against it you got 4 options to choose from. Solid product.
