Check the listing for details. Airsoft “Ray Gun Battery” Tracer Unit Stickers (2-Pack). Condition: New. Listed at 6.99 USD. *TRACER UNIT SHOWN IN PICTURES NOT INCLUDED* Ever wonder what exactly the Ray Gun is powered by? Turns out, it’s powered by two cold cell nuclear batteries that go directly into the gun itself. Those are the things your character throws into the ray gun during the reload animation. Now, you can apply some flare to your Acetech Brighter C tracer unit with a sticker inspired by Call of Duty Zombies. Although the sticker was specifically designed for the Acetech Brighter C, it’s possible that it could fit other similar size tracer units. The sticker occupies 48mm of vertical space and can sufficiently wrap around a tracer unit with a diameter of 28mm Application is easy. Start off by peeling a corner off the sticker, then apply part of the sticker onto the tracer unit. For best results, try to avoid peeling the sticker all at once and instead peel it off as you apply. Sidenote: This would probably go well with the AceTech Bifrost M using the green color function 😉 ————————————————————————— *This listing complies with eBay's air gun policy and I will only ship air guns to buyers in jurisdictions where permitted to by applicable laws https://www.ebay.com/help/policies/prohibited-restricted-items/airsoft-air-rifle-bb-guns-policy?id=5045
