HPA 13c Buttstock Currently, on version 4 as I upgraded the inner diameter to 50.50mm after discovering that while the Tippmann 13Ci measures 50.48, the FS 13Ci measures 50.12, and it was impossible to secure the bottle when its inner dimension was 51mm. Currently printing at a rate of 1.11. Version 4 (50.5mm) fits perfectly over the FS 13Ci but not the Tippmann. Version 5's inner part is 51mm and should fit both Tippmann and FS bottles, while Version 4's inner part is 50.5mm but due to shrinkage it will likely be close to 50.1 in my ABS prints. UPDATE: With ABS, Version 5 will indeed fit both FS and Tippman bottles.
