Full Length Talon Claw U Bullpup - Cyrow

thingiverse

A full length version of Captain Slug's U-channel Talon Claw Bullpup, called the Cyrow. 25.25 inches overall length. 16 inch length of pull. 3.75 inch stroke (only 0.375in less plunger travel than the normal TCB). Uses the same hardware kit as the normal Talon Claw U Bullpup, along with a Caliburn plunger rod cut down to 5 inches, and a caliburn o-ring set for the small plunger o-rings. The hardware kit requires some minor modifications. Assembly instructions are essentially the same as the normal Talon Claw U Bullpup. Fits a K31 or K26 spring cut to 6.5 inches. The 788 and K25 don't fit the plunger the same way and need to be cut very short (4 7/16 inches) in order for the blaster to prime, which is too short to be useful (in my testing the 788 performed worse than the K31 at these lengths). Gets ~120 fps with the K31. Doubling the K31 and the short 788 gets ~180 fps. The K26 gets ~220 fps. For the top rail, you need to print one CBPRailD and three COGrail_4C. A model and image of the modified caliburn ramrod is included for dimensions of the added o-ring notch (Caliburn_Ram2core_Cutdown_5). A one piece 3D printable version of the ram+ramrod is also included if you lack the tools to modify the metal ramrod (Ram2oe+5inOringRamrod). Hardware kit modifications: The plunger tube gets cut down to 5.48 inches long. An extra hole is drilled into each of the U channels. See images for dimensions. The bottommost long bolt that holds the stock on needs to be cut to 1.125 inches so it doesn't collide with the sear. Extra screws from the hardware kit are used to assemble the trigger guard pieces.
