Now in stock at RSOV.com is the second generation M4A1 Blowback AEG from Army Armament. For those familiar with this "R" Series from Army Armament, these are basically blatant copies of the Tokyo Marui New Generaton Blowback and Recoil Series. We don't yet what are the improvements with the second generation, but should be good for those who don't have the budget to afford the Marui new gens and don't mind IP violations.
