Our take: The Magpul KWA PTS RM4 ERG comes with KWA’s new revolutionary Kinetic Feedback System (KFS) 3GX gearbox, and is fully outfitted with a Magpul PTS lower receiver, and MOE furniture. The KFS system takes the recoil and realism that you would normally expect from a GBB rifle and packs it all into the new KWA PTS RM4 ERG. KWA has taken their tested and proven 2GX gearbox and reinforced the internals for even more durability, added the unique cut off system for a quick crisp shot after every trigger pull, reinforced the gearbox shell itself to withstand the impact of the KFS recoil. Designed for professional training and hardcore MilSim players, this new KWA RM4 includes nearly all of the features of a GBB rifle with the convenience of an AEG. The full metal internals and externals, the new 3GX features, and the KFS system, the KWA PTS RM4 ERG proves to be one of the most unique and well-designed rifles on the market.
Note: The included RM4 magazine will only work with the KWA RM4 ERG.Other standard M4 style magazines will work with the RM4, however the rifle will no longer have the mechanical / electric cut off system if you do not use the RM4 magazines.
