[Set] FN MK46 MOD 0 SOCOM Light Machine Gun Replica [A&K] + 1.5x/6x Gen2 Optical Sight [Emerson]

2.2 jouls with M130 spring.
It sounds better with a 7.4 volt battery but does much higher RPS with 11.1
Overall it is a good deal especially for the price I got it which was 440€.
Quite heavy but it doesn't bother me

A machine gun like no ther, almost all of the replica is made of solid metal and steel making it close to the weight of the real one,Very consistent shots and nicce accuracy ,Very strong motor and gearbox perfect for long games and very easy to insert battery . probably the best Airsoft replica I ever held in my hands

This replica is a solid choice for anyone wanting to get into the support role.

It's well built, having all of the key components made from metal. There isn't any wobble or rattle, and the few re-enforced polymer parts are very durable.

There is much more space for the battery compared to the polymer counterpart, allowing you to use longer stick batteries.

Using a 7.4V Titan, I am able to hit roughly 12-15 rnd/sec. This is fine for me as I am not looking to empty my box mag in the first game :)

The sling points have held up fine. Easily holding the replica weight, a full box mag and the stress of me running around in a skirmish.

The stock has 5 points of adjustment making it easy to shoulder for different framed people. Its sturdy and easy to change positions for use/storage.

The handguards are all metal and the rails are accessable despite looking very cramped in the images here. The lower handguard installs and removes smoothly, and stays in place during play.

The box mag fed flawlessly and fit perfectly. After ~6000 rnds, I've had no issues :)

I regrettably had knocked off a star as the stock hop unit struggled to hop 0.25g BB's. Anything above that weight and it cannot hop at all. I tried changing the nub and bucking, but it didn't have any effect. It seems the rotary dial does not put enough pressure on the nub even when fully on.

The barrel was very "dirty" on arrival. It's hard to explain, but there looked to be streaks of oil and/or slight corrosion. After trying to clean the barrel with Iso-propyl alcohol and letting it dry, the streaky corrosion markings remained. I'm not sure if this affects the flight path of the BB's at all, but I was still dissapointed to see it.

To combat the hop issue, I had to purchase an aftermarket hop unit. I was not interested in modifying the stock hop chamber or trying to "shim" the nub.

Overall, I am very happy with the replica. It's heavy, so not for the faint of heart, but seems like it can take a beating. The ROF is perfect for how I want to play and I was happy to see that I could use longer batteries in the handguard. I've had no problems with the included box mag and haven't experienced any feeding issues at all.

If you like the platform and are ok with the weight, this is a great replica for a starting or seasoned support player.

The replica arrived few days after purchase, it was packaged in a Cybergun branded box, which contained the replica, magazine and a spare spring.
Externally the replica is Very well made, this version (atleast mine) has better fitment of the external parts, than standart A&K replica's have, everything is rock solid without any wobble, except for the stock, which wobbles on the buffer tube (that is a common problem and can be easily solved), also the making on the reciever is beautiful.
Performance of the replica with the strong spring wasnt as good, rate of fire was slow, after changing to the weaker spring (approx.M120 by weight) the gun started cycling nicely with solid rate of fire (measured at 16-18bb/s), the gun was chronoing at 1.6J (125m/s), which is perfectly for usual limits in some countries, the gun can hop maximum BB weight of about 0.3g and send them accurately to measured 50-55 meters, which is solid for a stock replica.

Internally the gun has kinda proprietary Hop-up chamber to standart M249's, since it has different anti-rotational pin placement and different feed Block than the old A&K's. The hop-up chamber is far better than the old A&K design, because it already has concave nub design and with a Begadi/MapleLeaf bucking and a little know-how it can lift 0.32g's perfectly with great range.

The gearbox internals are great compared to standart old A&K's, since the gun has a CNC steel cut gears (SHS OEM), Nylon body piston with full metal Teeth rack, Steel cylinder and aluminium Piston head+ cylinder head.
Only complaints about the gearbox internals are, that the cylinder head fitment isnt the tightest and the o-ring nozzle isnt sealing too well out of the box.
The motor is fairly standart (probably about 26-28tpa motor) with thin neodymium magnets, it has enough power for springs up to 1.7J of power, with the stronger spring in the box (2J of power) its not operating as well.

Conclusion:
This replica is perfect replica out of the box for someone who wants to play LMG role ať field with up to 1.7J limits, or a nice base gun for an upgrade, since it already has some parts that you will use in your upgrade.

It has some small flaws, that could be fixed, but almost none stock gun is perfect, so i give the gun 4/5 stars, since there is a small room for improvement.

!!! I Would personally 100% recommend to buy this gun if you want a LMG, more than the standart A&K variant!!.
