Description
Kel-Tec put a section of M1913 Picatinny rail on the back of the KP50 for exactly this purpose, and the KP50-1310 is the brace designed to live there. This is the same factory side-folding stabilizing arm brace that comes installed on the braced KP50 from Kel-Tec, so it matches the pistol's lines instead of looking like an aftermarket add-on. For anyone who picked up the base pistol and wants to bring it up to the full braced configuration, this is the genuine part straight from the source.
Why the KP50 Brace Earns Its Spot
The 5.7x28mm doesn't kick hard, but a four pound pistol feeding from a 50-round magazine still benefits from a third point of contact. This brace gives you a more secure, ergonomic interface that steadies the gun during longer range sessions, and the construction stays lightweight and rugged so you're not lugging around extra weight for no reason. The streamlined profile follows the KP50's shape closely, which matters on a firearm that was designed around staying compact.
Folds Flat, Packs Small
The side-folding hinge is the feature that really sells it. Fold the brace against the receiver and the whole braced KP50 setup shrinks to roughly 18.6 inches, which makes it a much easier fit in a backpack, range bag, or truck case. When you want it deployed, it swings out and locks up without any fiddling.
Simple Install, Factory Fit
Because the KP50 already wears that rear Picatinny section from the factory, installation is straightforward and there's no gunsmithing or adapter hunting involved. Mount it, snug it down, and you're set. It comes finished in black to match the pistol, and since it's a genuine Kel-Tec part, the fit and function are exactly what the platform was engineered for. If you're building out a KP50, this is the piece that completes it.

Frequently Asked Questions
Will this brace fit the original Kel-Tec P50?
No, this brace was designed around the KP50, which has a rear M1913 Picatinny rail section built into the receiver specifically for it. The original P50 does not share that mounting setup, so P50 owners typically need an aftermarket rail adapter to run a folding brace. If you have a KP50, this attaches directly with no adapters.
Is this the same brace that comes on the braced KP50 model?
Yes, this is the genuine Kel-Tec factory part, the same side-folding brace installed on the braced version of the KP50 from the factory. Buying it separately lets base model owners match that configuration exactly, with the same fit and finish.
Is the KP50 brace hard to install?
Not at all. The KP50 comes from the factory with a rear Picatinny rail section made for this brace, so installation is a simple mount-and-tighten job with basic hand tools. No gunsmithing or modification is needed.
How compact is the KP50 with the brace folded?
With the brace folded flat against the receiver, the braced KP50 measures roughly 18.6 inches overall. That keeps the whole package short enough to stow easily in a range bag or backpack, which is a big part of the appeal of the side-folding design.
