I've always thought that the hollowpoint bares more resemblance to the operating system of a FEP Quest than a traditional Ion bolt kit
(despite being an ion upgrade)
Yeah they are pretty similar.
Id say the quest is a step inbetween the shocker and the hollowpoint ion.
The quest, like the shocker doesnt pop off the valve guide it just moves an apeture to either fill or empty the bolt chamber.
Where as the hollowpoint, while configured like a quest bolt gets its simplicity from the ion design.
The seal is just done from the inside rather than the outside. Apart from that it works like every other 'tailless' ion bolt.
Many other ion upgrade bolts perform very similar to the Hollowpoint.
And the Orange one has a floating piston like the NT.
But my favorite is still the hollowpoint which I bought of you I think
