I can only name 3.
I believe the 2nd pic is a 2k3 Warped Sports Dark Autococker, which were a limited run milled by Ethan Steiner of FreeFlow/Professional Paintball from New York, USA
The 4th pic is a standard Eaton Ripper.
The 5th pic is a convertible (sight rail milled off) Eaton Ripper.
Here are my 2 latest (re-)builds.
The gloss blue bolt is a shocktech supalfy bolt. It is actually slightly longer than a true evo length bolt.
The white bolt is an Orange Hardliner-S Carbon Fiber bolt. It is the proper evo length.
