A very quick presentation by Gunfire on the KWA Ronin TK.45C 2.5 AEG... "When designing the Ronin TK.45 2.5 model, KWA attempted to create a replica of a submachine gun powered by pistol-style magazines. The gun is made of metal elements and durable polymer. In this version, the replica has a PDW stock, a quick spring change system, and a reinforced AEG2.5 Gearbox with adjustable muzzle velocity.

Airsoft Taiwan now has the new TK.45 AEG  from the Ronin "Tekken" series from KWA. slender aluminum 10 inch M-LOK free float rail and KWA’s Kinetic Feedback System (KFS), or as the TK.45c AEG 2.5, with KWA’s Variable Performance System (VPS) unit which means the FPS can be adjusted to meet game field requirements. In this video they test this feature.

Montreal-based airsoft retailer, Taktik Airsoft, got in stock the new KWA TK.45C and here is their take on this AEG... "A quick overview of KWA's latest offering in the Ronin family. The Tekken 45 has a more space-age look while keeping the overall platform familiar ergonomically. We were especially happy with the ambi controls, performance was typical of KWA RM4/VM4 series (20-23 rps in full-auto) with the exception that the Tekkens are compatible by default with after-market MOSFET kits."
