Arrived fast and was exactly what I needed :)
It makes a big difference. It’s a pain in the butt to get it installed but it’s definitely worth it.
Perfect spring for XS Longshot Pro upgrade. Paired with the aluminum plunger tube, this increased the FPS and accuracy significantly.
Order was fulfilled quickly, and safely. The Slab Hardware kit even came with the additional closed loop hairband for the catch.
Was easy to install, and what a difference!!
