Airtech Studios Tanker Battery Extension for KWA VM 6 Ronin PDW & TK45 Airsoft AEGs

"Get it… you need it. PDW stocks are cool but man, these batteries are small. I got this for the KWA EVE-4, but it fits all the KO series guns. You only lose the fully collapsed position so no big deal. Get it, throw in a 3000 mAh 11.1 and go tear it up.

"I can fit an 11.1v titan battery using this on a QRF mod 1

"I bought this for the QRF mod 2 as i was having issues with the battery being a very tight fit and i wondered if this could even fit on. Fortunately the extension fits into the pdw stock perfectly and gives plenty of extra space. This does prevent the stock from collapsing fully, but i keep it extended out anyways.

Strongly recommend if battery space is needed or the cover needs to be replaced

"i got this for my ronin 6 pdw. although the gun has pretty decent battery space for having a tanker stock i needed more to fit an 11.1v titan power battery. this extension gave me just the right length to fit it. from the picture it looks like it wouldnt match the texture of the stock but it matches and fits perfectly. if it didnt have the airtech logo i would think the gun came with it from the factory

"Purchased this for the KWA RONIN 6, and not only did it give the PDW stock more space, I was able to fit liPO 11.1v 1600MAH 20C battery in it comfortably. I will be trying out a 1800MAH 20C 11.1v soon, as I've measured the dimensions, it should fit with no problem. For those who own the TK.45 and Ronin 6 - this is a no brainer.
