The Krytac LMG Enhanced is exactly what the name says it is. Krytac took the concept of a traditional light machine gun and improved upon its premise, making it sleeker, more compact, and shoots semi auto! All the goodness in one gun, finally! What we have on the table is much more than just a M4 with a belt-fed upper receiver, various upgrades / enhancements have been made to make the gun stand out from the other competitors in the market such as the Stoner LMG and the M249. First off, the gun only weights 3.53kg / 7.78 lbs, which is substantially lighter than the other competitors. Secondly, the LMG-E features a Krytac Enhanced LMG Keymod rail system which helps with lowering the weight of the gun and having the flexibility to mount accessories such as fore grips, PEQ boxes, bipods and such. Externally there are also other enhancements for better functionality and ergonomics, such as the Licensed Defiance Pistol Grip, Krytac Battery stock, Six positioned buffer tube, Ambidextrous fire selector, Ambidextrous sling loops and a licensed CMC Flat face Trigger, which all would have the gun become a more controllable weapon.Internally the following features had been added for a more robust gearbox and perform much better even when undergoing sustained suppressive fire:8mm Ball Bearing Nautilus MechboxIntegrated FET SystemEasy Maintenance Spring GuidePadded Cylinder HeadRelief-cut Cylinder WindowAnti-corrosion Mechbox CoatingAdjustable Rotary Hop-UpTemperature And Wear Resistant Hop-Up BuckingKRYTAC 30k Neodymium Magniet High-Torque Moto Oh did we also mention the LMG-E comes with a large 3,500rd motorized box magazine?
