Description
Kinetic Development Group built this FDE brace to solve the biggest gripe SCAR owners have with pistol setups: getting something stable and adjustable back there that doesn't feel like a bolt-on afterthought. It mounts directly to the SCAR receiver through a purpose-made adapter, giving you a tight, wobble-free fit that feels like a factory part rather than a universal accessory forced to fit. The whole thing folds left at a slight 3.5-degree cant, which keeps it tucked in tight against the gun for storage, transport, or tight-quarters work.
What Sets the KDG SCAR Brace Apart
Adjustability is where this piece earns its keep. You get 7 length positions in half-inch increments, running roughly 7.6 to 10.6 inches, so you can dial the length of pull to your build and body. The 3-position cheek riser (0, +0.25, and +0.50 inches) lets you line up cleanly behind whatever optic you're running, and both adjustments are tool-free once you know the buttons. There's a sling loop plus two steel QD points at the rear for whatever carry setup you prefer.
Built to Take a Beating
KDG didn't cut corners on materials. The locking hinge is nitride-coated 17-4 stainless steel, the length extrusion is hardcoat-anodized 6061 aluminum with a 7075 aluminum locking latch, and the polymer components are injection-molded 30% glass fiber reinforced nylon. It's designed, machined, and assembled in the USA, and it fits the FN SCAR 15P along with the 16, 17, and 20S.
Choosing Your Brace
Worth knowing before you order: this is the pistol brace configuration, which ships with a brace mount sized for tube-mount style braces at 1.195 inches in diameter. The actual brace is not included, so you'll add your own. Popular pairings include the A3 Steady Brace and the Gear Head Works Tailhook MOD1 and MOD1C, so you can build it out exactly how you want it.

Frequently Asked Questions
Does the KDG FN SCAR Brace come with a brace attached?
No, this is the pistol brace configuration, so it ships with a brace mount but not the brace itself. The mount is sized for tube-mount style braces at 1.195 inches in diameter. Popular options that pair with it include the A3 Steady Brace and the Gear Head Works Tailhook MOD1 and MOD1C, which you'd purchase separately.
Which FN SCAR models does this brace fit?
It's engineered for the FN SCAR 15P and is also compatible with the SCAR 16, 17, and 20S. The brace mounts directly to the SCAR receiver through a purpose-built adapter for a tight, wobble-free fit. Because it's designed specifically for the platform, you get a clean integrated look without bulky universal hardware.
How adjustable is the KDG SCAR Brace?
Quite a bit. You get 7 length-of-pull positions in half-inch increments running roughly 7.6 to 10.6 inches, plus a 3-position cheek riser at 0, +0.25, and +0.50 inches. That lets you tune both the reach and your cheek weld to line up behind your optic, and the adjustments are tool-free once you're familiar with the buttons.
Is the folding hinge strong enough for hard use?
The hinge is built from nitride-coated 17-4 stainless steel and locks up positively in both extended and folded positions. It folds to the left at a slight 3.5-degree cant so it tucks in close against the receiver. Combined with the aluminum extrusion and glass-reinforced nylon body, it's made to hold up to real range and field time.
