Light Machine Gun M249

The M249, also known as the FN Minimi, is a light machine gun developed by the Belgian company FN Herstal in the 1970s. Initially designed as a multipurpose support weapon that combines high firing rate with relatively low weight. Thanks to its capability to fire from both magazines and belts, it offers versatility for armed forces needing flexibility.

The weapon was adopted by the U.S. military in 1984 under the designation M249 SAW (Squad Automatic Weapon) and became well-known for its reliability and ability to provide continuous fire support at short and medium ranges. It is used by armies worldwide today, available in multiple versions and modernizations.

What does the Specna Arms SA-F249 PARA FLEX™ GATE X-ASR™ offer?

Internal Components

The SA-F249 PARA FLEX™ GATE X-ASR™ replica is equipped with the MOSFET X-ASR module by the Polish company GATE. It ensures safe switching, protects internal components, improves trigger response, extends battery life, and increases firing rate, while allowing for the safe use of Li-Po batteries at 7.4V and 11.1V. Integrated status LEDs allow the module to diagnose basic weapon faults.

The weapon comes with a 6.03 mm precision barrel and an adjustable Hop-up chamber with a quality rubber for excellent range.

It also includes the increasingly standard QSC ESA (Quick Spring Change) system, allowing you to install a stronger or weaker spring as desired. The spring can be replaced easily by folding back the stock without needing to remove the gearbox.

AETHER™ gearbox is reinforced and works with springs up to M135 (as specified by Specna Arms in its PRIME™ models).

External Components

The Specna Arms SA-F249 PARA FLEX™ GATE X-ASR™ replica stands out for its high-quality external construction of the M249 nylon body with an upper RIS rail, which features a matte finish and a realistic appearance. Reinforced with fiberglass, the body is both highly durable and lightweight.

The outer barrel is made of metal, and the screws and pins are even made of steel. The lightweight design ensures comfortable handling and easy operation—this machine gun just feels right in the hands!

The nylon RIS handguard allows for attaching various accessories like a grip, AN/PEQ box, flashlight, etc.

The battery is inserted under the cover above the gearbox. This is a machine gun that combines lightweight construction and excellent internal components at an attractive price.
