Description

Introducing the T3 MC51 RIS from JG, a solid performing AEG assault rifle with a polymer body, keeping the rifle light, wieldy, and affordable. Based on the real MC51, a short variant of the G3 battle rifle, the real firearm fires the big boy 7.62x51mm, and comes with a G3 style high capacity magazine holding a whopping 500 rounds! Equipped with a fixed stock with a much larger than normal battery compartment, this variant of the MC51 is a great platform for both indoor and outdoor skirmishes.

The real MC51 was designed at the request of the SAS, who required a short barrelled rifle with improved stopping power over the MP5's 9mm cartridge. The design was trialled but never entered service due to its monstrous muzzle flash and recoil. These rifles still see use by civilians in America, where the culture seems to value blinding light and deafening noise as a way to "one-up" a friend's latest firearm purchase, primarily for entertainment value.

Starting at the tip we find the alloy G3 style flash hider which threads onto the 14mm CCW male threads at the tip of the alloy outer barrel. The outer barrel is around SMG5/MP5 length, making the MC51 RIS a manoeuvrable platform for room clearing in CQB. As we move rearward we come across the front sight, which is made from alloy and is a fully hooded design, protecting it from damage. Integral to the front sight block we can find a sling loop, mounted to the left side of the sight block. Behind this, we can see the pin which retains the RIS handguard; simply push the pin through from the right side to remove the handguard.

The handguard is entirely constructed from aluminium with alloy mounting parts and provides 18 slots of Picatinny rail on the sides and 16 slots along the bottom - plenty of space for vertical foregrips, flashlights and lasers should you wish to take advantage of this platforms modularity. Attractive vents machined into the handguard keep the rifle lightweight and give the front end an aggressive form factor.

Above the handguard lies the polymer cocking tube, within which resides an alloy HK style charging handle, which actuates the mock bolt and allows access to the rotary HOP unit inside the receiver. The charging handle can be locked to access the HOP unit more easily but we do not recommend doing the "HK slap" with this rifle, due to its polymer construction.

The cocking tube leads back to the polymer receiver, which features the ejection port on the right side, and two grooves along either side allowing the sliding stock bars to travel within, keeping the sides of the rifle flat and slim to prevent snagging. Atop the receiver, we can find the rear iron sight, which is a rotary drum aperture type sight providing 4 differently sized apertures to aim through depending on the range you are shooting at and the level of precision required.  Between the rear sight and the ejection port there are 4 raised lugs moulded into the receiver, providing a mounting point for G3 and MP5 type receiver rail mounts, should you require an optical sight. A low-profile receiver rail is included in the box, ready for your optic!

The magazine uses a "rock and lock" style insertion, allowing the magazine to lock into the rifle reliably with little chance of it falling out. The magazine can be released in two ways; with the ambidextrous "paddle" protruding at the bottom of the receiver ahead of the trigger guard, and with the button release, found on the right side of the receiver above the paddle. The lower receiver/ fire control group is made from polymer, and features an ergonomic pistol grip, providing a solid and comfortable grip for both right and left-handed users. The fire selector, found on the left side, features a textured extension to ensure your thumb can easily move it between modes without slipping off.

The stock of the MC51 RIS is a full-sized G3 style stock, with an alloy receiver end cap and polymer body, with a rubberized butt plate, designed with deep texturing to ensure the stock of the rifle can be shouldered with confidence that it will not slip off the shoulder. Within the stock we can find the battery compartment of the JG103, which can be accessed by pushing the butt plate down, after which it can be lifted free of the stock body. Inside, you will find a mini-Tamiya connector to which your battery connects. For the JG103 we recommend a 7.4V 1300mAh nunchuck battery or a 9.6V NiMH block battery.

The internals of the JG T3 MC51 RIS are in line with the other rifles in the T3 series; sporting a version 2 gearbox with full AEG compatibility, a rotary drum style HOP unit providing ease of adjustment and less likelihood of losing its setting due to vibration, and a 6.08mm inner barrel boasting full compatibility with aftermarket tight bore barrels. The T3 MC51 RIS is perfect for anyone who wants a mid range rifle, with widespread compatibility which can achieve any objective set for it.
