Plunger Head Shim for Nerf Kronos / Heracles (and possible other Kronos reshells)
Place this shim on the plunger head underneath the O-ring for a tighter seal.
Same concept as the oldschool teflon tape wrapping method to tighten seals; but more permanent -I've had issues with teflon tape squishing out of place.
SML variant doesn't stretch the O-ring as much. use if the tighter seal adds too much drag and becomes a detriment to fps.
Plunger Fill Spacer:
the Kronos Plunger Tube has a very slight Taper at the front;
This narrow area can damage the O-ring seal if using the Above Shim to get a tighter fit.
Therefore, must press fit this shim into the bottom of the plunger tube to block the plunger from entering Tapered section.
Sacrifices a few mm of air volume, in exchange for Seal Durability.
Warning: may need to remove Ratchet Lock from blaster after shimming, depending on spring/spacers used.
Impact resistant material recommended; such as high durometer TPU.
