From the onset of every project, Magpul uses a list of mission-driven requirements to dictate design, material construction, and manufacturing methods that will be most efficient without sacrificing quality or performance. The goal of the design itself is to be both simple and intuitive. By incorporating ergonomic considerations, a proper user interface, and subtle visual and tactile features, the product itself should actually instruct the user about its operation and function

All Products > LWRC M6 5.45x39 Piston Upper
*48 States, this item only.
The LWRCI M6-AK upper is an M6A2 style upper chambered in the 5.45x39mm cartridge. It features a 16” barrel with A2 flash hider. It has the LWRCI Mark 1 ARM-R rail system and utilizes LWRCI’s patented short-stroke gas-piston operating system.
The bolt carrier is coated in a nickel-teflon-boron coating that promotes permanent lubricity and allows the gun to be run with little lube. The barrels are treated with our NiCorr process (a type of salt-bath nitride) that renders them extremely corrosion resistant. The NiCorr is done on the whole barrel including the bore. We are getting 20,000 rounds out of our 5.56 barrels that use this coating with little to no degradation in accuracy.
The other thing that makes these uppers attractive is that they all come with full-auto carriers. Anyone with a registered lower or a drop-in auto sear can use these uppers as-is right out of the box.
The 5.45x39mm cartridge was developed as the Soviet’s answer to the American and NATO countries 5.56x45mm cartridge. It was chambered in their AK-74 rifles and it’s ballistics closely mirror those of our 5.56 round.
Why buy a 5.45x39 Upper?
There are currently large quantities of this ammo available to American shooters at incredible prices. Most of the surplus ammo is mildly corrosive, so careful cleaning of the rifle is required after every session. One great advantage of shooting this ammo out of a piston gun as compared to a direct impingement gun, is that all of the dirty / corrosive propellant gases are vented at the gas block instead of being blasted back into the receiver where they can foul not only the upper but the lower as well. The cleaner operating characteristics of piston guns make sense with any ammo but when shooting corrosive ammo it becomes a no brainer.
