The MEAN MA Lock is a shear bolt mechanism designed to lock MIL-SPEC AR-15 and AR-10 magazines in place. Developed for states with intrusive laws requiring fixed magazines, installing the MA Lock makes AR firearms legal and compliant, leaving all your favorite tactical features in place. Installation of the MA Lock provides a true solution to fixed magazine laws, thus eliminating the requirement to register your rifle with your local government.
MA Lock allows firearm to conform to California law when used to mount a 10 round magazine permanently. MA Lock replaces the spring and magazine release push button. The operator removes the magazine push button and spring to replace with MA Lock. Operator installs the bushing then threads the hex shape onto the magazine catch in place of the button. The hex shape is then tightened until the head shears off to permanently mount the magazine catch.
An unintended consequence of the new intrusive fixed-magazine laws is possible compromised safety. With no ability to quickly load an unloaded AR rifle for home defense, gun owners may inevitably choose to keep them loaded at all times. This action potentially puts the people we are committed to defend at risk. The use of a MEAN MA Loader solves this problem and is considered by some as the safest solution for all AR rifle owners. Simply keep your AR rifle unloaded with an MA Loader close by. One quick motion and you are loaded and ready. Please view our MA Loader videos for more details.
