**These parts are sold as-is and are BLEMISHED from a poor anodizing process. Functionality of these parts are the same as normal parts, but may have discolored black hardcoat and / or 1 or 2 tiny specs, not anodized on the part usually on an edge. We have a small batch of these you can same $20.00 off due to this. ***

After several requests for a solution to use Sig 1913 braces and stock and SBA Tactical braces and other 1913 mounted hardware with the Masterpiece Arms MPA MPA30T MPA57DMG MPA30DMG MPA30SST MPA30TGR 9mm mac 10 clone weapons. We decided it was time to build one for our local customers and for you to buy. We hope you like it as much as we like it, we use a locating pin unlike others to ensure super solid mounting for worry free use for years to come. Bolts directly to the factory holes on the back of your weapon and allow for use of 1913 attachments, 1913 stocks and / or braces. Rail is offset to allow folding to the left of the weapon (may not work with folding to the right stocks and / or braces)

 
Kit includes:
 
Adapter / Adaptor plate MOUNT 1913 rail for MPA30T and variant mac 10 clones made by Masterpiece arms with aluminum lowers.
Locating pin
3 Bolts and lock washers
 
 
No shipping outside of the USA due to ITAR

    MPA Defender brace adapter

    Posted by Tony on Oct 15th 2025

    I ordered this adapter to add to my MPA Defender 30T. It went on easily and I really like the way the locating pin goes into the backside to really add some extra rigidity. I ordered the "Blem" to save a little money and honestly I didn't really notice anything unusual. It works and thats all that matters to me. Definitely satisfied with the quality of the product for the price point.
