Half the weight of an aluminum bolt means a faster cycle rate and less impact on the ball (read: less breakage). Super smooth Delrin material means no lubrication necessary. Replace your existing bolt with the CORE Delrin Spyder Bolt. Fits Spyder Imagine, Spyder Pilot, Spyder Victor, Spyder Victor II.
The CORE Delrin Spyder Bolt is older, so while it may be available used and in a few cases new, it is not commonly available anymore.

Delrin ACS bolt
Cheap (around 10$)
Venturi, dunno if you prefer it or not...
Low flow, due to venturi.
This a perfectly decent bolt, I have nothing much to compare it with really, its ot a honeycomb sort of venturi, I've hear lots of controversy about whether venturis are good or bad, so I guess its a matter of preference.
I bought this with my imagine, and because I'm totally new to this, read the reviews and heard about the bolts scratching and stuff, so I grabbed this for an extra 10$ when I bought my marker, it works perfectly well, and is one of the fewer delrin bolts using o-rings (one of the complaints I heard about delrin bolts is that they have no o-rings) of course i didn't know that bolt scratches were park of marker break in.. so..
I got the delrin acs from my brother for Christmas, so I have yet to check that in comparison.
Its all preferance, this is a perfectly decent bolt, the only bad bit, the fact that its low flowing, but some people prefer that...

VENTURI kills efficiency
I got one of these for ~$10 because i was tired of constantly lubing my stock bolt to prevent heavy scratching. The first thing i noticed was it had a milled air port with a cure shape to it the air port was also much larger than the port on my stock bolt. Before i even used this thing i put it in the drill press and used a 3/8" bit to drill out the venturi i probably could of drilled it out farther but i was afraid that i would weaken it too much so i left it at 3/8"
Only drilling it to 3/8 left little ridges inside. which should help straiten the air flow so it hits the ball more evenly. Because of the higher flow it will make the gun more efficient and add 100 shots to your shot count. Now i can get over a case worth of paint out of one 20oz tank.
I highly recommend this bolt to anyone especially if its been drilled out like mine. I give it a 9 because it requires machining to make it perfect.
