Frequently Asked Questions

What makes the KAK Industries 11.5-inch barrel ideal for suppressed shooting?

This KAK barrel is designed with a specific gas port size (.075/.076 inches) and a mid-length gas system on an 11.5-inch barrel. This combination creates limited dwell time, which is optimized to cycle reliably when a suppressor is added, increasing back pressure and effectively extending the dwell time for smooth operation without tuning.

Can the KAK 11.5-inch barrel be used for unsuppressed shooting?

No, this KAK 11.5-inch barrel is specifically designed for suppressed use and is not intended to run reliably unsuppressed. Its gas port is sized to require the back pressure from a suppressor to properly cycle the firearm's action.

What are the key specifications of the KAK Industries 11.5-inch mid-length barrel?

The barrel is 11.5 inches long, features a mid-length gas system, is chambered in 5.56 NATO, has a 1:8 twist rate, is made from 4150 steel, is dimpled from the factory, and has a 1/2x28 thread pitch. Its profile is described as 'middleweight'.

What type of suppressors work best with this KAK 11.5-inch barrel?

Traditional baffle-stack suppressors are recommended for this barrel as they provide sufficient back pressure to ensure reliable cycling. Flow-through suppressors, which reduce back pressure, may not provide enough gas impulse for this specific barrel configuration to function correctly.
