CARROLLTON, GA –-( MasterPiece Arms announces the Defender Carbine Models MPA1SST, MPA20SST and MPA9300SST now meet and exceed the State of California’s requirements on the sale and ownership of semi-automatic center-fire rifles.

California restricts the sale and possession of semi-automatic center fire rifles with the capacity to accept a detachable magazine and other specified features.

California regulations, however, exclude magazines that require the use of a tool to be removed from being deemed “detachable magazines.” Our new CA line of MPA Defender Carbines meets and exceeds these requirements by developing our magazine lock design thereby rendering the magazine “non-detachable” under California law.

The new design includes the absence of the protruding tab at the bottom of the magazine catch, which normally permits the user to push with the thumb and remove the magazine. The tab has been machined flush with the main body of the magazine catch with a precision hole added at a 30 degree angle. The removal of the tab eliminates the ability of the user to remove the magazine unless an external tool is used. To remove a California compliant Defender Carbine magazine, the user inserts the MPA provided tool into the precision hole and pushes downward, actuating the internal magazine release system.

The new California compliant MasterPiece Arms Defender Carbines include the MPA20SST-CA, a 9mm side-cocking Defender Carbine, the MPA9300SST-CA, a 9mm Carbine based on the Mini 9 Configuration and the MPA1SST-CA, a .45 ACP side-cocking Defender Carbine. All come with a scope mount, 10 Round Non-Detachable Magazine, Tool, Muzzle Break and 16.25-inch threaded barrel.

The MasterPiece Arms Defender California compliant pistols will be released in the very near future.

So, if I buy one of these in Florida will it be "California compliant"?

The answer better be 'no', else I will never own one. Actually, given MPA knuckling under to the morons who run California, it's fairly likely I'll never own anything by MPA.

While I have nothing against MasterPiece Arms or their line of excellent firearms, back-engineering a weapon to meet "CA. STANDARDS" is sheer preposterous nonsense!! I hope they NEVER sell a ONE in CA.!! …ENOUGH with the LIB THINKING. We NEED to be exporting LIBS to CHINA, is what America REALLY needs.
