Airsoft Outlet Northwest announce new stocks from the KWA, especially the ERG and the AK-74 PTR Gas Blowbacks... "The KWA Magpul PTS RM4 ERG and AKG-74 series were first announced at SHOT Show 2011, and finally almost here! It's been a long wait, but the KWA RM4 Electric Recoil Gun represents the most realistic electric training rifle available.

Here's a video from Magpul PTS about their new RM4 series that use KWA's ERG... "The PTS RM4 series of guns are variations based on the M4/AR-15 platform. The ERG (Electric Recoil Gun) RM4 system represents the continued evolution of the AEG (Automatic Electric Gun). Core features include a mechanical / electrical cut-off with the last round fired, functional bolt release, and simulated recoil via the proprietary Kinetic Feedback System.

Greg Wong, or better known as Spartan1117gw on YouTube, gets his hands on the Magpul PTS RM4 ERG together with the US-based guys of Magpul PTS, Jeff Takeda and Alex Ko. The ERG is the KWA's electric recoil and blowback offering that they want to give stiff competition to the Tokyo Marui New Gen AEGs, and the Bolt Airsoft BRSS. The ERG, just like the BRSS is still compatible with standard Marui M4 magazines unlike the Marui New Gen. Watch carefully to learn more about it.
