Hammershot Spring Spacer for the FPS

thingiverse

You can expect this blaster to reach 80 FPS when configured correctly with a clear flow-path and a secure seal between the cylinder and piston chamber. To get the most performance, you'll need an un-restricted path for the air to flow freely. The unique design of this spacer captures the spring, providing a solid foundation rather than simply resting on top of it like other spacers. This is especially important because a loose spring can cause issues after several rounds, eventually working its way over the spacer and damaging the coils in the process. Fortunately, this particular spacer has been designed to prevent this problem from occurring. Additionally, as [44sunsets](https://www.thingiverse.com/44sunsets/about) notes, it also fits perfectly on grey-triggered Doublestrikes.
