KWAs new TK.45 Series represents a momentous leap forward in the evolution of the KWA lineup. Diving head-first into the AR pistol and PCC fray, KWA offers the AEGs in two distinct options. The first is as a field-ready AEG 3 carbine with a slender aluminum 10 inch M-LOK free float rail and KWAs Kinetic Feedback System (KFS) sitting inside of a PTS Enhanced Polymer Stock. The CQB version, dubbed the TK.45c, offers a 6 inch KeyMod rail and KWAs new compact tanker stock which can also be found on their Ronin 6 PDW. The TK.45c is an AEG 2.5, so it features KWAs VPS unit for a quick, simple FPS adjustment through the stock without the need to get into the mechbox. Both models feature quick-change spring systems that add even more customizability to the series.Like all current KWA rifle offerings, the receiver of the Tekken Series is full metal, but also features contemporary billet-styling on both the upper and lower, further enhancing the aggressive and modern look of the AEG. Perhaps most noticeably, a signature feature of the series is the angled polymer magwell that doubles as a foregrip and allows for improved weapon manipulation, which is especially apparent in the shorter TK.45c when rounding corners and working in tight spaces.The controls on the TKs also display the thought that went into this project, with ambidextrous, oversized, billet-style magazine and bolt catches and selector switches, complementing the overall design of this modernistic line. Other details that are hard to overlook are the ambidextrous charging handle, a first for a KWA AEG, an enlarged trigger guard for gloved hands, and a comfortable, ergonomic pistol grip with custom stippling that also appears on the grip panel of the Tekken 120 midcap.Internally, the Tekkens are updated with spacing to receive drop-in electronic trigger units such as the Gate TITAN (not included), and also contain the recently upgraded high-torque gear set, circuit protecting Switch Life Extender, upgraded high-torque motor, and a reinforced and radiused mechbox. The rotary hop-up has also seen some design improvements and in test runs performed beautifully. As with all KWAs, the Tekkens will come stock with a 6.05 Japanese-made semi-tightbore inner barrel to help maintain accuracy with the new hop-up unit.
