Frequently Asked Questions

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

The FN SCAR Gen 2 features a redesigned two-piece bolt carrier group with a hydraulic buffer for reduced recoil, an extended receiver with M-LOK handguards for accessory mounting, and an ambidextrous trigger module compatible with AR-style grips.

Is the FN SCAR Gen 2 backwards compatible with older parts?

Yes, FN America has designed the Gen 2 SCAR components, including the bolt carrier group and trigger module, to be backwards compatible with legacy SCAR rifles, allowing for easier upgrades and maintenance.

What is the benefit of the hydraulic buffer in the SCAR Gen 2?

The hydraulic buffer in the SCAR Gen 2 significantly reduces recoil impulse during both the rearward and forward strokes of the bolt carrier. This results in a smoother shooting experience and less harsh impact on the firearm's internal components.

Does using a suppressor on the SCAR Gen 2 affect its warranty?

FN America officially supports the use of specific low back-pressure, forward-venting suppressors. Using approved suppressors will not void the warranty on critical components like the trigger module or bolt carrier group.

What changes were made to the SCAR Gen 2's accessory mounting system?

The Gen 2 SCAR receiver has been extended and now features M-LOK handguards, replacing the traditional Picatinny rails. This provides a more modular and lighter platform for attaching various accessories.
