FS1913 FOLDING PICATINNY PISTOL BRACE
SB Tactical FS1913 Folding Brace 9.25″ — SIG Sauer MCX / MPX, Black
So your MCX or MPX needs a proper folding brace that locks solid in both positions without rattle or slop. This is it. The SB Tactical FS1913 folding pistol brace, 9.25 inches, black. Left side-folding. Advanced steel hinge. Locks open and locked closed. Ships directly across Europe — no RFD transfer required.
This FS1913 FOLDING PICATINNY PISTOL BRACE is not a universal clamp-on brace. First, the FS1913 connects directly to your MCX or MPX via the factory M1913 Picatinny interface at the rear of the receiver — no adapter, no modification, no tools needed for installation. Next, the polymer and steel construction keeps weight low without sacrificing the solid lockup that makes this brace worth running. Finally, the pull-through deployment gives you one-handed operation when you need it fast.

Does This FS1913 FOLDING PICATINNY PISTOL BRACE Fit My SIG MCX or MPX?
Yes — directly, with no adapter. So the FS1913 uses the M1913 Picatinny interface that SIG builds into the rear of every MCX and MPX receiver. Also, this same interface is used by the SIG Rattler, the Grand Power Stribog, and the Rock River LAR-PDS. Therefore, if your platform has a 1913 rail at the rear of the receiver, this brace connects straight on.
Does This FS1913 FOLDING PICATINNY PISTOL BRACE Require Any Transfer Documentation in Europe?
No. So the FS1913 FOLDING PICATINNY PISTOL BRACE is an accessory component — it is not a firearm. Therefore, it ships directly to you across the UK and Europe without RFD transfer or import firearms documentation in most countries. However, your MCX or MPX must already be legally owned and registered in your country. Therefore, sort your rifle’s legal status first, then add this brace without any additional paperwork.
How Does the Folding Mechanism Work?
Pull-through opening, steel hinge, locks in both positions. So you pull the brace outward to deploy — one-handed, no buttons, no levers. Also, the advanced steel hinge locks the brace positively in the extended position so there is zero movement during use. Finally, it locks equally securely in the folded position, so the brace stays compact and does not flap around during transport. Therefore, you get a genuinely professional folding solution, not a budget wobble-brace.
What Is the Weight and Size?
Light and compact. So the FS1913 weighs just 10 oz — minimal addition to your platform. Also, the extended length is 9.6 inches, with a maximum width of 1.2 inches and a 1-inch strap width. Therefore, the folded profile is genuinely compact, making your MCX or MPX significantly more manageable for transport and storage.
Who Is This FS1913 FOLDING PICATINNY PISTOL BRACE Best For in the European Market?
This FS1913 FOLDING PICATINNY PISTOL BRACE fits MCX and MPX owners across Czech Republic, Switzerland, and other European jurisdictions where these platforms are legally permitted. So the SIG MCX and MPX are popular among European sport shooters who value the short-stroke gas piston design and modular calibre capability. Also, Grand Power Stribog owners across Slovakia and Eastern Europe will find this brace directly compatible. Therefore, if you run a 1913-interface platform and want a compact, solid folding solution without any paperwork, this is it.
