Cybergun FN Licensed M249 MINIMI "Featherweight" MK46 Airsoft Machine Gun – Lightweight LMG Power with Full FN Licensing

Bring battlefield-level support to your airsoft squad with the Cybergun FN Licensed M249 MINIMI "Featherweight" MK46 Airsoft Machine Gun, a game-changing support weapon designed for mobility, durability, and relentless firepower. Fully licensed by FN Herstal, this lightweight LMG offers the iconic look and proven combat reputation of the M249 while delivering airsoft-friendly handling and performance.

Lightweight. Not Light Duty.

Don’t let the term "Featherweight" fool you—this M249 packs serious performance. Designed with fiber-reinforced nylon polymer in the receiver, handguard, stock, and bipod, the MK46 variant trims nearly half the weight of traditional full-metal M249s. Weighing just 8.8 lbs (4kg), this LMG allows you to maintain high mobility while dominating the field with sustained full-auto fire.

Built Tough for Combat Realism

The MK46 variant maintains a rugged battlefield aesthetic while enhancing usability with modern upgrades. The aluminum alloy barrel assembly includes a metal locking mechanism for strength and realism. A rotary hop-up dial provides accurate BB flight tuning for mid- to long-range suppression. Compatible with most M4/M16 AEG magazines, it comes stock with a 300-round magazine, but can also accept box mags for heavy suppressive roles.
