Caliburn K14 Kit

thingiverse

Ever felt overwhelmed by those powerful air blasters while using your Caliburn? Ever felt like you needed a more substantial spring to handle the load?\r\n\r\nEnter the K14, a massive 24.9kg spring with a perfect length for the Caliburn. With this kit, you can easily double the spring power of your Caliburn, resulting in significantly higher FPS. To install the spring and ensure proper alignment, three printed pieces are necessary, which I print at 50% infill in PLA. I also use an X-Profile O-Ring that greatly improves the stock seal of your Caliburn's ramrod.\r\n\r\nKits and Springs are available at my Etsy shop if you don't have a printer or need a spring: https://www.etsy.com/shop/Remzak?ref=l2-shopheader-name\r\n\r\nTo install the kit, simply replace the three stock printed pieces with their similar-looking reshaped counterparts, install the spring, and the new O-Ring. I recommend doubling the O-Rings on your plunger piece for an improved seal, and doubling the small O-Rings on the ram to improve the seal there. A longer barrel or tighter barrel is essential, without them you will be seriously underutilizing the spring and risking major damage.\r\n\r\nWARNING: This spring induces increased stress on all parts of your Caliburn, specifically the spreader from my conversations with CaptainSlug. I have not broken, damaged, or seen stress marks on my stock spreader (PLA 100% Infill) through hundreds of shots, but know that it is an inherent risk. If using this kit you should be using an upgraded barrel (your own/sold separately) to utilize the power, which will help protect the plunger. Using this kit with darts that are a loose fit in the stock barrel will induce unnecessary wear. Early iterations of this kit had trouble with the catch slipping, since implementing version 3 of the design I have had no issues. If you have issues, a tight rubber band around the rear of the sear solved any problems I had with early parts. This is an extremely strong spring, use it at your own risk.
