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 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. 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
Locating pin
3 Bolts and lock washers
No shipping outside of the USA due to ITAR

    MWS/MPA 30T Picatinny rail adapter

    Posted by B Perri on May 19th 2022

    This adapter is just the ticket for attaching an arm brace to this particular model Mac 10 clone. Excellent design, fabrication and finish round out this adapters pros. The only possible thing that would pit this adapter over the top would be incorporation of a QD Mount on the top or bottom of the aluminum adapter. Great service from MWS!

    Great product for adding a brace to MPA pistols

    Posted by Josh on Dec 3rd 2021

    This product is exactly what's needed to attach 1913 and other picatinny braces/stocks to the back of MPA Defender pistols. It's very durable and fits the gun very nicely.

    Exactly what I was looking for

    I bought a similar piece elsewhere and quality was very very poor. I was concerned about buying another part from a small company. I received this one and was blown away perfect finish great quality overkill on how it mounts. This one is solid as a rock and folds over without running into the back corner of the gun. MWS builds great parts hope to see you guys make more cool stuff soon for my MPA pistol.
