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 of a lighter weight souped-up Version 2 gearbox. Full specs of the gearbox internals can be found below.

About the M249:
The FN M249 LMG was born out of true necessity; a need for something lighter than the M60 while still being able to provide ample suppressive firepower. This lightweight evolution of the machine gun is currently in service in the hands of the US military, as well as over 75 other nations around the world.

Based on the FN Minimi, the M249 uses a 5.56x45mm NATO cartridge in a belt-fed configuration, supplied from a plastic box magazine. In a pinch, you may also use STANAG compatible M16 magazines in this weapon system. Over the years the M249 has seen quite a few variants, all purpose-tailored to individual's needs.

"This gun is perfect for anyone who doesnt want to run a heavy 16 pound lmg. They replaced alot of the medal externals woth nylom reinforced polymer so its a lot less heavy. The hopup needed to be adjusted but when i got it adjusted it hit accurate upp to 300 feet. As a left handed person i thought this was made perfect for lefties.

Light mine with all the attachments only weighed about 13 lbs
Rate of fire was good
Made for left handed people (pro or con)

Needs a bit of work when it gets here
Very low battery space

"alright, ive had this for a week now but haven't gave it field time with this pandemic

lemme just say out of the box it looks awesome, very sturdy gun with no wobble at all, stock is firm when you get it attached. i did have one issue with the sack mag and that was a feeding issue but it was stupid easy to fix, now for how modifiable this bad boy is lemme say this, if you get the a/k m4 stock adapter you WILL have to do some filing and get a bigger pin to reach the other hole as well as drill out a place for youtr bat connector to reach through

otherwise this gun is awesome for a budget LMG

"So after playing 3 or 4 games with this gun and completely disassembling the gearbox, I think I’m qualified to write a review on it. The main theme you’ll probably see in this review is: great for the price.
The polymer body is ok for what the gun costs, but I wish the rails were metal as they have a bit of wobble and part of my top rail popped up during a game, tilting my sight down. No idea why it happened, a firm whack fixed it. When you get this gun, the stock will be separate. Punch the pins in from the right side, the holes on the left are too small to allow for the teeth on the pins. Every pin on this gun is punched in from the right and out from the left. The stock has a bit of up and down wobble when deployed, could be fixed with a spacer between the body and the top stock tube. Performance was really good for a $220 LMG, was able to lay down a lot of fire on a 7.4 without motor heat issues. Range was good, and after about 250 rounds the hop up began to feed more reliably. I fit a Valken 7.4 nunchuck under the top cover just fine. Mine shot 370 with .20 bbs. When I opened up the gun, I found a radiused shell to prevent cracking, a ported piston responsible for the gun’s relatively good consistency, and a full metal rack piston. It came with some grease in the gearbox, but in weird places, and the motor was too far out for the bevel gear to engage, causing a weird sound when fired. Gears are shimmed pretty well considering the low cost of this piece. All in all, good for a $220 SAW. Weight isn’t too bad either.


-Loud, amazing for suppression
-good performance considering the price
-internals are built for efficiency and durability
-light weight
-amazing price
-extremely easy disassembly

-small battery space (use a 7.4 nunchuck)
-rails and parts of the body can creak and bend, gaps between top cover and receiver
-makes screeching sound when fired, even though motor height has been adjusted and gearbox lubed
-no semi auto (gun design con)

If you want to get a SAW at the lowest price possible, pick one up! Performed quite well even in comparison to some higher end LMG type guns, at half the weight and cost!
