About .308 Winchester

.308 Winchester is a well-established .30-caliber cartridge used for target shooting, hunting, and general range use. One of its most practical characteristics is the amount of factory ammunition available, including everyday range loads, hunting ammunition, and match-oriented options. That long history also gives shooters plenty of published information for comparing different loads.

Compared with 6.5 Creedmoor, .308 Winchester commonly uses a broader selection of .30-caliber bullet weights, while some 6.5 Creedmoor loads can have a flatter trajectory and less wind drift at longer distances. Neither cartridge guarantees a particular accuracy result. The ammunition, barrel, and shooting conditions all affect performance.

.308 Winchester is closely related to 7.62×51 NATO, but the two follow different ammunition specifications. Follow the chamber markings and the manufacturer’s guidance for your particular rifle.

Fitment and ordering

This barrel is sold as listed. Confirm that it is compatible with your SCAR 20 and the components in your rifle before ordering. Looking for another length, twist, or finish? See our custom SCAR 20 .308 barrel options.

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. Our gas block uses a sleeker design without the built-in sight, giving you the freedom to choose your own sight setup.

Our design retains adjustable gas regulation for suppressed and unsuppressed operation, similar to the FN system. We have tested our design with a variety of suppressors. This explains our gas-block design in general; the components included with a particular barrel assembly depend on that product’s specifications. Have a question about a specific suppressor or handguard? Reach out to us before ordering.

Important: FN SCAR Gas Block

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 before ordering.

When a Deadshot Barrels FN SCAR barrel assembly is supplied with a fitted gas block or barrel extension, those supplied 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. Return and warranty policy.
