If you want an LMG but don't want an M249, here is a tasty alternative! The Golden Eagle 6669 MCR LMG AEG is based on the real steel FightLite MCR LMG, a cutting-edge light machinegun platform based on the prolific M4/AR-15. The Golden Eagle replica boasts full metal construction and Tokyo Marui AEG spec internals, meaning upgrade options are practically infinite and ergonomics are far superior to the chunky and cumbersome M249 SAW.

On the outside, the Golden Eagle MCR is the spitting image of the real thing, down to its fluted outer barrel, aluminium KeyMod handguard, railed top cover and sliding M4/AR-15 6-position stock. Inside, everything is standard M4 AEG spec, including the 3-position fire selector which allows this LMG to cut around in close quarters with the rifle and SMG users, unlike the full-auto-only M249. If you want a lesser-seen LMG platform that is equally realistic and doesn't have to wait outside like an unloved pet when the team moves indoors, the MCR is perfect for you!

Description

If you have your ear to the ground when it comes to the latest real steel platforms, you will know the MCR! The Golden Eagle MCR is based on the real steel FightLite MCR, an M4/AR-15-based light machinegun focussed on modern ergonomics and agile handling. Unlike the M249 we are all familiar with, the MCR is almost as light as a normal full-metal M4 and handles similarly thanks to its M4 lower receiver, and also boasts a semi-automatic fire mode which allows it to turn and burn with other rifles indoors while most full auto only LMGs have to wait outside.

Internally, the MCR is practically identical to the standard Tokyo Marui spec M4 AEG, meaning the sky is the limit when it comes to internal upgrades. Externally, the MCR is also compatible with M4/AR-15 AEG pistol grips, sliding stocks and trigger guards for those who simply must customise everything. If you need an LMG which is less common than the M249 SAW and comes with its own perks, the MCR is the one!

Starting at the muzzle we can find an M4/AR-15 birdcage flash hider, a familiar sight. This mounts to male 14mm CCW threading on the tip of the lengthy 18.5-inch fluted outer barrel. The barrel is one of the things that make this AEG a beautiful sight to behold. The barrel tapers towards the tip giving the LMG its sleek look and perfectly mimicking the real MCR. Its fluting extends the full length of the barrel and is perfectly machined. Mounted on the barrel is the mock gas block, complete with mock piston, front iron sight and carry handle. These parts are a mix of alloys and steel, keeping the components strong.

The front sight is a unique type but the blade is a standard M4/AR-15 front sight blade, ensuring Ar users have a sight picture they are familiar with. The carrying handle is mounted on the right side of the gas block and can be removed using the large steel locking screw. There are deep grooves machined into the carry handle to provide additional grip whether the user wears gloves or not. The carry handle also fulfils the role of providing something to hold onto in the real firearm when using its quick-swap barrel function, a hallmark of a proper LMG.

To the rear of the carry handle, we can find the KeyMod/Picatinny handguard, which provides a 20mm Picatinny rail on the top, 6 KeyMod slots at the 3 and 9 o'clock position, and 7 KeyMod slots at the 6 o'clock position. This gives rails where you need them while keeping the overall setup light and pointable. The provision of KeyMod slots on the sides and bottom allows mounting of any KeyMod compatible bipod, or a 20mm Picatinny bipod with the appropriate rail sections.

The handguard also provides two steel QD sling sockets, one on the left and one on the right side of the LMG, allowing both right-handed and wrong-handed people to sling it. Unlike with most QD sockets equipped platforms, the Golden Eagle MCR includes 2 QD swivels in the package; one installed on the handguard QD socket and one on the stock. How generous!

Next up, we reach the receiver, which has a large catch on the top to release the outer barrel. In the real firearm, holding this catch down allows barrels to be swapped when the weapon heats up from extended firing. For Airsoft purposes, this is simply for realism purposes, as the outer barrel can be removed but the inner barrel and HOP-up unit stay fixed in place.

Behind the barrel removal catch, we come to the upper receiver/top cover with its is a raised 20mm Picatinny rail which allows for a red dot sight or scope to be mounted right away. The receiver rail is machined as a part of the mock feed tray, which can be raised when the release button at the rear left of the feed tray is pressed. The Golden Eagle MCR comes with a set of detailed mock 5.56mm cartridges on a dummy belt which can be installed between the included box magazine and the feed tray, completing the realistic exterior.

The included magazine is a whopper, to say the least. An autowinding electric box magazine with sound control mode and a massive 2500 BB capacity, just as any LMG needs! The magazine is filled up just like any other high-cap mag; through the fill window at the top of the magazine body. The battery compartment is on the bottom, requiring 4 x AAA cells (not included).

The activation switch is on the right rear of the mag body, with the central position being "off", the right position being the sound control mode and the left position being the autowinding mode. Sound control means an internal microphone will keep the magazine feeding as the AEG is fired and the autowinding mode will automatically wind the magazine as long as the switch is in this position. Sound control is what you will want to use most of the time, but if you prefer you can choose when your magazine winds you can make use of the autowind function.

At the rear of the feed tray mounted rail, we have a low profile M4/M16 style ghost ring aperture iron sight, which combines with the front sight blade to give a familiar sight picture to M4 and M16 users. Like the M4/M16 sight, this can be adjusted for windage using the dial on the right side, and has two apertures to choose from, with a large ring aperture for full-auto fire/close range and a small aperture for precise shots. The upper receiver has a mock ejection port on the right side, through which the adjustable HOP-up unit can be accessed.

The HOP-up unit is a standard M4/AR-15 type gear adjustable unit, providing quick and easy adjustment when the charging handle is held to the rear. Unlike an AR-15, the charging handle on the MCR is on the left side of the receiver and can be folded flush for transportation and to reduce snagging. The bolt release on this rifle is non-functional, though it is still present on the left side of the upper and takes the form of an enlarged bolt release catch. Though the bolt release is non-functional, the charging handle provides all the satisfying click-clack noises you will ever need, actuating the mock bolt carrier with each pull. To the rear of the mock ejection port there is no forward assist or shell deflector, in their place is a large weight-reducing groove, keeping the weight of the MCR low, barely heavier than a standard M4.

As we move to the lower receiver, we arrive at the familiar aspects of the MCR. The lower is a standard AR-15 design, with the fire selector present on the left side above the pistol grip and the magazine release appears on the right side, accessible in a firing grip using the trigger finger. The lower receiver has engraved "SAFE-SEMI-AUTO" markings surrounding the selector switch, so you can avoid using safe and semi, as this is an LMG! The trigger is an enhanced ergonomic design, providing a greater contact surface, and is also weight-reducing with a machined hole, avoiding the addition of even the smallest amount of unnecessary weight.

The trigger guard is a standard M4/AR-15 flat type, providing plenty of room for using gloves but can be exchanged for any M4 AEG-compatible trigger guard. The pistol grip is an "A2" standard design, with a finger ridge and checkering on either side and the rear, to ensure you have a secure grip at all times and in all weather conditions. At the rear of the LMG, we can find a 6-position AR-15 standard buffer tube, which allows the use of M4/AR-15 AEG sling plates and stocks, at the users' discretion.

The MCR comes with an ergonomic stock, featuring 6 positions of adjustment and an ergonomically curved butt plate allowing for using body armour and shouldering the LMG high on the shoulder in tight spaces. The stock features a raised cheekpiece, which provides space for a block battery of around 1300-1600 mAh to be installed within. We recommend a 7.4V 1300mAh LiPo battery in block configuration for an easy fit and great performance.

To install the battery, simply remove the butt plate by unscrewing the two Allen locking screws, and the cheekpiece will come straight off. The battery can then be installed inside, and the cheekpiece re-attached. Alternatively, you can store your battery inside the buffer tube itself if you prefer to use a 7.4V 1300mAh LiPo stick battery.

At the rear of the stock, we are provided two additional steel QD sling sockets, one on the left, and one on the right. The MCR LMG comes with two QD sling studs, which can be removed and installed on any of the 4 sockets present on the weapon.

Internally the MCR LMG uses a standard version 2 gearbox and a common M4/AR-15 gear adjustable HOP-up unit. The internals are fully compatible with any aftermarket parts intended for standard M4/AR-15 AEGs. The pistol grip houses a long shaft motor, compatible with all aftermarket replacements. Basic though the internals may be, the path is open for future upgrades thanks to full Tokyo Marui AEG spec internals!

If you are planning an LMG build but want to start with something a bit different with vastly superior ergonomics than the common M249, the Golden Eagle 6669 MCR LMG AEG is the one to go for. Being M4/AR-15 based gives you access to an absolutely massive aftermarket for upgrades and a semi-automatic function, meaning this LMG is welcome at CQB sites and semi-auto-restricted sites. There is nowhere to hide from the Golden Eagle MCR AEG!
