Description
The KDG FN SCAR Brace is one of those upgrades that makes the factory setup feel like an afterthought. Kinetic Development Group built this in collaboration with Haga Defense and A3 Industries, and it shows in the fit and finish. It's purpose-built for the FN SCAR 15P platform, mounting directly to the receiver through a platform-specific adapter for a clean, factory-like interface. It also plays nicely with the 16, 17, and 20S models, so most SCAR owners can find a home for it.
Where this brace earns its keep is adjustability. You get a 7-position telescopic length running from 7.6 inches to 10.6 inches in half-inch increments, plus a 3-position cheek riser with 0, +0.25, and +0.50 inch settings. Both adjustments are quick and tool-free, so dialing in your length of pull and cheek weld happens on the fly. At roughly 1.15 pounds in brace configuration, it keeps the balance of the gun in check without adding dead weight out back.
Built Tough: What Goes Into the KDG SCAR Brace
The materials list reads like a parts sheet for something that isn't meant to break. The locking hinge is nitride-coated 17-4 stainless steel and folds to the left canted at 3.5 degrees, which keeps the profile tight when stored. The length extrusion is hardcoat anodized 6061 aluminum with a 7075 aluminum locking latch, and the main body is 30% glass fiber reinforced nylon. That combination gives you a folding mechanism that locks up tight in both open and folded positions without the wobble people complain about on lesser adapters.
Setting Up Your FN SCAR Brace
This version ships in the pistol brace configuration, meaning it comes with a tube-mount style adapter (1.195 inch diameter) ready to accept your brace of choice. Compatible options include the A3 Steady Brace and the Gear Head Works Tailhook MOD1 and MOD1C. Installation is straightforward with basic tools, and once the adapter is secured to the receiver, the whole assembly comes together fast. Rounding it out are a rear sling loop and two steel QD points for whatever sling setup you run.

Frequently Asked Questions
Which FN SCAR models does the KDG FN SCAR Brace fit?
It's engineered specifically for the FN SCAR 15P and mounts directly to the receiver for a seamless fit. It's also compatible with the SCAR 16, 17, and 20S models through the same modular mounting approach. The 15P is where you'll get the most dialed-in, purpose-built result.
Does the KDG SCAR Brace come with a brace attached?
No, the brace tail itself is not included. This model ships with a tube-mount style adapter (1.195 inch diameter) that accepts your choice of brace. Compatible options include the A3 Steady Brace and the Gear Head Works Tailhook MOD1 and MOD1C.
How adjustable is the KDG FN SCAR Brace?
Plenty. You get a 7-position telescopic length running from 7.6 to 10.6 inches in half-inch increments, plus a 3-position cheek riser at 0, +0.25, and +0.50 inches. Both adjustments are tool-free, so you can fine-tune length of pull and cheek weld quickly in the field.
How solid is the folding hinge on this brace?
The hinge is built from nitride-coated 17-4 stainless steel and folds to the left canted at 3.5 degrees for a tighter stored profile. It locks up firmly in both the open and folded positions, which keeps play and wobble to a minimum. It's one of the sturdier folding setups you'll find for the SCAR platform.
