Full description

Description

Introducing the 6673 MCR LMG, a faithful reproduction of a real-world light fighting Support weapon. Combining LMG function with AR15 ergonomics has been attempted many times in the real firearms world, allow us to take you through what sets the MCR LMG apart from the rest...

Starting at the muzzle we can find an M4/AR15 birdcage flash hider, a familiar sight. This mounts to male 14mm CCW threading on the tip of the 14.5-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/AR15 front sight blade, ensuring users of the AR15 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 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 will be most likely to need them whilst keeping the overall setup light and pointable. The provision of KeyMod slots on the sides and bottom allow mounting of any KeyMod compatible Bipod, or a Picatinny Bipod with the appropriate rail sections. The handguard also provides two steel QD sling points, one on the left and one on the right side of the LMG, allowing both right-handed and wrong-handed people to sling it.

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 unit stay fixed in place. Behind the barrel removal catch, there is a raised Picatinny rail, which 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. 

With a box magazine installed, this allows the MCR to have mock rounds installed, adding to the realism of this Support weapon. 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 unit can be accessed. 

The HOP-up unit is a standard M4/AR15 type gear adjustable unit, providing quick and easy adjustment when the charging handle is held to the rear. Unlike an AR15, 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 lightening 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 AR15 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 lightened with a machined hole, avoiding the addition of even the smallest amount of unnecessary weight. 

The trigger guard is a standard M4/AR15 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 an AR15 standard buffer tube, which allows use of AR15 AEG sling plates and stocks, at the users' discretion. 

The MCR comes with an ergonomic stock, featuring 6 positions of adjustment, 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 1600 mAh to be installed within. 

To install the battery, simply remove the butt plate by unscrewing the two Phillips locking screws, and the cheekpiece will come straight off. The battery can then be installed inside, and the cheekpiece re-attached. 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/AR15 gear adjustable HOP unit. The internals are fully compatible with any aftermarket parts intended for standard M4/AR15 AEGs. The pistol grip houses a long shaft motor, compatible with all aftermarket replacements. The MCR is supplied with a 300 round wheel or key wound High capacity magazine but is compatible with most M4/AR15 AEG magazines, including box and drum magazines.

Those looking for a light machinegun that also have the American disease of not being able to handle anything that isn't based on an AR15, you can now sling plastic with the M249 bois safe in the knowledge that you don't have to learn anything new!
