Kc Arms

KC Arms focuses on what they know best: Heckler & Koch firearms and the gunsmithing to customize them. Located in Haslet, Texas, they sell select HK models and handle the technical work to make them yours.

On the retail side, KC Arms stocks HK firearms including the SP5-SD suppressed 9mm semi-auto pistol (available in sear-ready versions, $6,800–$7,325). They also carry HK 53, HK MP5 SD, and P5K-N models.

For gunsmithing, their services include:

• •Barrel installations ($325–$775)
• •Barrel threading for suppressors
• •Build parts kits for custom assembly
• •Paddle flap installations with parts included

If you need work done on an HK platform, they handle it in-house.

They're reachable by phone for questions about ordering, custom work, or availability. Email works too if you're planning a specific build.
