The Badger Ordnance TDX Gas Manifold is an ultra-low profile gas block designed specifically to fit beneath slim, narrow free-float handguards without causing contact or interference. Machined from robust 416 stainless steel and finished in a corrosion-resistant black nitride, this component is engineered to handle extreme heat, gas erosion, and harsh fouling during high-volume strings of fire. Sized with a 0.875-inch inner diameter, it provides a rock-solid, repeatable seal on heavy-contour precision rifle barrels. The assembly drops smoothly onto standard AR-pattern barrels and secures tightly using two premium stainless steel set screws to lock your direct impingement gas system firmly into index.
