Frequently Asked Questions

What are the main upgrades in the FN SCAR Gen 2?

The FN SCAR Gen 2 features an extended M-LOK handguard for better accessory mounting, a new two-piece bolt carrier group with a hydraulic buffer for reduced recoil, and fully ambidextrous controls. It also includes a heat shield over the gas regulator and uses Torx screws for easier maintenance.

How does the hydraulic buffer improve the SCAR Gen 2?

The hydraulic buffer in the Gen 2 SCAR significantly reduces recoil impulse on both the rearward and forward strokes of the bolt carrier. This design manages the carrier's kinematics, preventing harsh bottoming out and providing a smoother shooting experience.

Is the FN SCAR Gen 2 compatible with suppressors?

Yes, FN America officially supports suppressed use with the Gen 2 SCAR, recommending low back-pressure, forward-venting suppressors. Using approved suppressors will not void the warranty on critical components like the trigger module or bolt carrier.

Can Gen 2 SCAR components be retrofitted to older SCAR rifles?

FN emphasizes backward compatibility for many Gen 2 components. The trigger module, bolt carrier group, and barrels (with a specific yoke) can often be retrofitted to legacy SCAR rifles, allowing older models to benefit from some of the new features.
