Ontos Buck-Fifty Remix

My local club plays at 150fps, and all of our Ontos builds were hitting at least 180. One of our members discovered that a 225mm barrel combined with this 1.3 x 248 Kunlun spring from Out of Darts allowed the blaster to reliably and consistently hit an average of 150fps. The only problem being that a 225mm barrel does not stick out past the collet. So I modified a few of the parts and came up with this remix.

20mm has been removed from the front body and the slide so that the priming distance is still the same. With the weaker spring, the smaller slide does not introduce any issues. The collet has also been remixed to use a straight thread instead of a tapered one, and instead of clamping down around the barrel, it pushes the barrel firmly back into the breach to secure it in place. For this reason, it's important to make sure the length of your barrel is exactly 225mm. Barrels that are 1-2mm longer will probably work fine, but shorter barrels won't.

There are three choices of collets included with this set:

- The “Dart Zone” spec muzzle, which will allow the use of press fit dart zone rifling devices like their BCAR or SCAR. - The WhiskerPCAR, which is 100% printed rifling that doesn't sap too much speed from the darts - The BC DCAR v2, which is a 10 degree 3x3 rifling device that uses metric M3 bolts and imperial #4 washers instead of bearings. Very cheap to put together. Special thanks to BaconCreations for providing the STEP files for this. This file set only includes the modified parts. You will still need to get the rest of the parts from the main Ontos file set. Please refer to the Ontos build instructions for assembly and printing orientations.
