Color Options:


  • Fully licensed by FN Herstal
  • Heavy duty design with a rugged yet lightweight feel that is ideal for fast paced games and long days on the playing field
  • Constructed almost entirely from high strength, fiber-reinforced nylon polymer (receiver, handguard, top cover, stock and bipod)
  • Aluminum alloy barrel assembly with metal locking mechanism
  • Rotary dial hopup provides precise adjustment
  • Electronic trigger with inline MOSFET for optimal electrical efficiency and performance
  • Metal gearbox with tricked out internals (specs below)
  • Quick-change spring guide
Light machine guns, like the FN M249, have been a vital asset on the field for years. Usually the job of lugging one of these bad boys around falls on the shoulders of the strongest person on the team, but today that all changes. This FN Licensed M249 Para "Featherweight" Airsoft Machine Gun solves all the woes of wanting an LMG on the field, but not having the strength and/or willingness to carry it around all day. This M249 weighs in at a reasonable 8lbs, shedding almost 50% of the weight compared to its full metal counterpart! Fear not though, just because it's lightweight doesn't mean it's weak and flimsy. The receiver and chassis are made from a fiber-reinforced nylon polymer that's constructed in a super high strength design, making this featherweight option extremely durable.

The FN M249 Featherweight has also shed some pounds by discarding the original brick-heavy standard M249 gearbox design in favor lighter weight souped-up Version 2 gearbox. This gearbox has been outfitted with an electronic trigger system and inline MOSFET, making this gun not just convenient but also a truly formidable Airsoft weapon. Full specs of the gearbox internals can be found below.

"My M249E2 came in, the stock has Tons of space, unlike the other varients with small stocks and no space the E2 can fit Literally any NiMH and LiPo battery on the Airsoft Market. I reccomend getting the Matrix 2000 Rnd Tan (Black) box mag as a replacement box mag. A&K Box mags may be unreliable, I have seen bad reviews from A&K's box mags but perhaps its a user error or it could be a manufacturer error. Regardless if you're looking for a replacement box mag look into the Matrix 2000 Rnd Box mag.

"This is a very good machine gun for anyone looking for their first machine gun. it is light, has a good fps and fire rate, and it is light.

good fps
good rps
looks cool
loud (Could be con for some)
quick change spring and barrel. no dismantling gun for accuracy and fps upgrades.

you need to keep the barrel and chamber clean in order to keep it feeding properly with a box mag.
small battery compartment

I recommend that you through a m120 spring in there for a better fps, but even stock it is a very good gun.

"Got it in a box of awesomeness so value around $100 more or less . test ok 300fps no issues using box mag 1500 rds with the reinforce motor model. The good news about this gun:
1- Looks better than A&K I have the full metal para
2- Weights less than an M4 ( Berrett carabine)
3- easy HPA upgrade you ever done just drop in a Jack all you need Amped chim for polar star 1.52mm that holds engine steady in V2 gear box, M60 nozzle #14 , and a couple of gear chims for the trigger so it wont wobble left to right ( make sure you do not tide the screw in front and rear of trigger too tide check trigger movement).
4- Price
The no so bad:
1- Hop up unit I am trying replacements made of aluminum ( the original works but is plastic and Im running 28 rps Im afraid it will brake down the road)
2- Tripod just remove it is 2 or 1 screw easy put a vertical grip
