There website claim is 24 grams total weight with pin, however my digital scale both at home and work say 25, I blame my scale :P
a quick weight comparison here:
^Orange Bolt
^Stock Karnivor Bolt
^Eclipse Dart Bolt
^Osiris Bolt

a 99 Right Feed Venturi Bolt
As you can see the Orange Bolt weighs significantly less than anything but a halfblock bolt (and actually I put the eclipse pull pin in there, since the included pin was made out of stainless steel !!!)
Before installing I chrono'd the marker out back with some Diablo Heats, firing through a CCM with a .689 insert. at 195 working pressure the marker was firing at 260 FPS. +/- 6 (25 shots fired) After installation of bolt the marker was firing 263 +/- 7 (25 shots fired).
Recoil difference if there was any was negligible, it felt as if the bolt had a bit more drag, however that could be my imagination since I have no real way of measuring it.
so my breakdown:
Pros: Extremely light 25vs 36 grams!
Seems to be good airflow design
eh... looks neat? heh
notched for detent. (I would assume less bolt and detent wear)
Cons: Price! - 60$s
2 piece design (so maybe durability issues though none noticed thus
far)
