This page is for a couple custom bolts I've made for my own markers. This page only includes simple bolts for stacked-tube markers; I've made lots of other bolts for spool valve systems but they're more complicated and deserve pages of their own.
Excalibur:
This bolt was milled to reduce a bit of weight. Not much of a difference, but at least it's something. I left a full-diameter chunk in the middle for stability.
Impulse:
I converted this Adrenalin bolt to a nice, small, stubby version of its former uselessly-heavy self.
Shocker Sport:
I made this bolt from scratch, for use in one of my old brick Shockers.
Shocker SFT - HE modification:
This is one of the older delrin stock bolts which I modified for HE system by adding an o-ring groove and an additional array of ports.
Quest 4B Bolt:
This item has a page of its own: Quest 4B upgrade bolt
