About the 6mm ARC chambering

6mm ARC, short for 6mm Advanced Rifle Cartridge, was developed by Hornady. It uses a 6mm (.243-caliber) projectile and was originally designed around the dimensional constraints of AR-15-sized platforms.

Although 6mm ARC shares some cartridge-family characteristics with 6.5 Grendel, they are distinct chamberings. Their ammunition is not interchangeable. Likewise, 6mm ARC should not be confused with 6mm Creedmoor, .223 Remington, or 5.56 NATO.

This listing describes a specific FN SCAR 16 barrel and bolt combination. Its chambering alone does not establish compatibility with every existing rifle configuration.

Compatibility and fitment

This item includes a barrel and bolt as described by Deadshot Barrels. Compatibility with other components and the complete firearm should be confirmed before installation or use.

The gas block, barrel extension, and other assembly components were not individually specified in the original item details. Their inclusion should be verified with Deadshot Barrels rather than assumed.

What Do the Gas Block and Barrel Extension Do?

Gas block: The gas block is part of the SCAR’s piston operating system. It routes gas from the barrel into the operating system, with the gas regulator controlling that flow.

Barrel extension: This is the steel component at the rear of the barrel where the bolt locks into place. It’s an important part of the finished barrel assembly.

About Deadshot’s Gas Block Design

Some traditional FN SCAR gas blocks incorporate a folding front sight. Deadshot’s gas block design uses a different exterior configuration without that integrated sight.

Deadshot’s gas-block system retains adjustable gas regulation and has been tested by the manufacturer with various suppressor configurations. This describes Deadshot’s design generally; it does not establish which gas-system components are included with this particular item.

For questions about component inclusion, suppressor compatibility, or a specific firearm configuration, consult Deadshot Barrels.

Parts not included: Deadshot FN SCAR barrels and barrel assemblies do not include a gas piston or gas-regulator knobs. Customers must use compatible FN or aftermarket components. Confirm compatibility with your specific SCAR model.

When a Deadshot Barrels FN SCAR barrel assembly is supplied with a fitted gas block or barrel extension, those components are part of the completed assembly.

Do not attempt to remove, replace, or modify either fitted component yourself. Improper removal or alteration can damage components and compromise safe operation.

If a component appears missing, damaged, or incorrect on arrival, do not install or use the assembly. Contact Deadshot Barrels with photographs before making changes.

Damage or malfunction caused by gas-block removal, reinstallation, substitution, or modification is not covered as a manufacturing defect. Unrelated manufacturing defects and legally required remedies remain covered.
