The first and only fixed magazine compliance kit to make Sig Sauer 556R and 556XI rifles and pistols California/NY Legal without modifying the firearm. With MagLatch installed your firearm is no longer deemed an "assault weapon" by restrictive states. Our kit installs as easy as inserting a magazine. Our compliant device converts your firearm bypassing assault weapon registration requirements. MagLatch 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 top loading is recommended for fastest reloads. When traveling to free states disassemble the action and remove the modified magazine from the lower receiver.

Fits on Sig Sauer 556R and 556 XI rifles and pistols chambered and accepting 7.62x39mm Russian magazines.

Kit includes:

  • MagLatch Modified Magazine
  • Adjustment tools
  • Installation Instructions

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.
