MCX / MPX SAFEMOD Mag Lock Button
Building on the great success we have had with our SAFEMOD Mag Button, we have engineered a version that work with the Sig Sauer MCX / MPX rifles and pistols.
The MCX / MPX SAFEMOD™ is made from aircraft-grade 6061 aluminum alloy and Type II anodized in matte black.
Installation is simple:
- Ensure the firearms is unloaded and verify clear
- Remove the factory-installed magazine catch, spring and release button
- Install SAFEMOD™ with factory magazine catch.
- Insert appropriately-sized magazine into the firearm that you wish to be permanently attached
- Determine which length screw you will use by test-fitting both into the button. The one that doesn't protrude is the correct one
- Apply threadlocker (Not Included) sealant to the included set screws
- Thread the set screw into button until it bottom out.
- Use a 7/64 drill bit (Not Included) to remove the hex drive in the set screw
- Use the included two-part epoxy to backfill the screw holes
- Function test to ensure that the magazine is permanently attached
Installation is a snap. Just remove your old magazine release button and replace it with ours. Use the included set screw to prevent the button from being pressed. From our experience, we have seen a variation in the lower receivers for MPX / MCX. Some of them have a small recess that requires a slightly longer screw, which is why we include both screw lengths.
According to the NY SAFE ACT from the NYS Governor's website on the SAFE ACT, "Rifles requiring registration are: Semiautomatic rifles capable of receiving a detachable magazines." According to this definition of the law, by removing the capability of the rifle to receive "a detachable magazine," we reasonably believe that the firearm would be exempt.
** NOTE: DO NOT BE CONFUSED BY OTHER AR MAGAZINE LOCK STYLE DEVICES WHICH ALLOW THE MAGAZINE TO BE REMOVED AFTER BREAKING THE ACTION DOWN. IT IS OUR UNDERSTANDING THAT THESE ARE NOT LEGAL IN NYS **
Don't be fooled by the copies and imitations of our SAFEMOD that are out there. We are the original designers and manufacturers of the set-screw style magazine button lock. Often imitated, never duplicated.
