Airtech Studio TBE KWA Ronin PDW (Tanker Battery Extension)

The Airtech Studio TBE KWA Ronin PDW (Tanker Battery Extension) is a practical stock extension for players running KWA PDW-style platforms who need more usable battery space without making the gun feel bulky. It creates extra room inside the rear compartment so the battery, fuse and wiring can sit more naturally, helping to prevent sharp cable bends and unnecessary pressure on the pack.

In use, that means easier battery installation and less hassle when closing the stock back up before a game. It is especially useful for players who want to run a larger LiPo for longer skirmish days, with support for batteries up to approximately 152mm x 19.5mm x 11.75mm. Once fitted, the rifle stays compact enough for CQB handling, so you keep the tight, manoeuvrable feel that makes the Ronin PDW platform popular.

Another key benefit is improved stock stability. The extension helps lock down the two metal rails, reducing unwanted movement in the butt-stock and giving the rear end a more secure feel during aggressive movement and shoulder transitions.

Made from tough, flexible nylon, this Airtech Studio battery extension is designed to fit neatly with the original layout and installs without modification. It is compatible with the KWA TK45C, Ronin T6, Ronin 47, QRF MOD.1, QRF MOD.2 and QRF MOD.3, making it a smart addition for players refining a compact KWA AEG. For a cleaner rear-end setup, it also makes sense alongside suitable LiPo batteries and charging accessories. Add one to your build and make your KWA PDW platform easier to live with on game day.
