It depends on the length

Originally developed by FN Herstal, the FN MAG® is a global benchmark, currently in service with 90 nations across all operational environments. The combat-proven machine gun is engineered for the 7.62x51mm NATO cartridge, with hundreds of thousands of units adopted across the globe, ensuring full interoperability across allied defence forces. The new FN MAG® TACTICAL with Long Rail is the only package solution that integrates day and night operational capabilities, and refined ergonomics within the general purpose machine gun (GPMG) category. 

Designed differently 

The FN MAG® TACTICAL with Long Rail GPMG incorporates enhanced ergonomics that enable seamless adaptation to new equipment and fast and reliable aiming, alongside a rail for in-line day and night or thermal imaging capabilities. While initially adopted for sniper and assault rifles, this evolution in technology is now being extended to machine gun applications.

Key features include:

• Long 11’’ monolithic Picatinny type top rail: Designed for accepting approx. 14’’ of operational space for in-line day, night, or thermal optics while maintaining the use of original iron sights. With optimised eye relief, the rail also features an ambidextrous and symmetric feed cover latch based on the FN® SIDE-CLICK system, allowing effortless opening of the cover from either side.
• An enhanced feed cover retention mechanism: For improved handling, the FN® AUTO-LOCK retention system holds the feed cover open during loading, unloading or clearing the gun. The mechanism has a built-in opening stop at 62° to preserve optics, and in that position, it can retain up to 2.5 kg optics.
• Long, articulated carrying handle: Ensures balanced transport and is fully compatible with barrel changes when full size in-line optics are fitted.
• Adjustable tactical buttstock: Enhances user ergonomics and target acquisition through a 3-position length and 6-position cheek rest adjustment. Featuring an integrated folding shoulder rest and soft butt plate, it remains fully compatible with the original GPMG operating system without requiring modification.

These modern enhancements not only apply to the original FN MAG® but are compatible across all configurations, such as M240s (US designation) and L7A2s (UK designation). They are available with all new weapon orders or via a separate kit that allows local armourers or technicians to complete the conversion in minutes using basic tools. Alternatively, the tactical buttstock is available as a stand-alone upgrade. ALL INFORMATIONS abaout the new FN MAG Long Rail.
