Whew! Great looking Systema M4 at RedWolf Airsoft, and it's a limited edition. And being a limited edition, it comes ­with a whooping price tag - US$4,288.00... "Here's something you don't see every day! While every man and their dog accessorize the M4 AEGs look like the mos­t tactical weapon on the block, aftermarket parts for those models don't fit the Systema PTW series that easily.

Where there's a will there's a way, so we set out to make something really special out of this PTW.  Being as the internals are already of the highest quality money can buy, the works with them is limited to a professional installation. The gearbox features all machined and heat treated steel gears and a powerful high torque motor, able to handle all of the Systema cylinders from M90 (included) through M110, M130 and M150! (M110, M130 and M150 sold separately. M150 requires 12 volts to operate.)

The most striking change in the outlook of this electric work of art is the monolithic VLTOR-style upper receiver / free floating handguard, which is custom CNC machined from a solid block of aluminum. The finish is hard-anodized to military specifications, and it is incredibly realistic in every regard! The lower receiver is also CNC-machined, and it showcases the Prime CNC-machined receiver with STAG markings. The stock is a custom model of the latest kind for adjustability and ergonomics an old LE-stock can't offer. The grip is a genuine Magpul MIAD (not the PTS), also customized to house the motor but retaining the full range of grip panel options.

From between the vent holes in the railed handguard, you can catch a glimpse of another piece of machined metal, only this time it's stainless steel: An Airsoft Surgeon steel outer barrel with a length of 12". A Dytac low profile gas block as well as a Phantom flash hider with a direct-mounting silencer was also added to improve the looks and diminish the muzzle pop.
