First off, let me explain what some of these coversions mean.
Halfblock - The top tube behind the feed is almost completely removed, the bolt and pump arm are shortened, and the gun becomes top-cocking.
Midblock - The same as a halfblock however most of the top tube is left in-tact.
Mini - The bottom tube in front is shortened flush with the top tube and re-threaded for a gas-screw/frontblock.
Midget- The bottom tube at the rear is cut flush with the grip frame. Can also usually be done to a regular cocker with an evo bolt and 2k block combo.
Micro - An autococker with a mini, midget, and halfblock/midblock conversion.
Osiris - Think Intimidator inside, cocker outside. Uses an autococking system paired with an intimidator style firing system. This is here because you can get conversions done.
MQ valve(MQ2 valve) - Technically a conversion because it changes your gun to fully electro-pnuematic. I'm not going into detain over the rise and fall of PBX, but Kerry A. Johnson has on his site KaJohnson.com. He re-vamped and now sells the MQ2 valves with another original designer calling themselves MTX.
Now a few websites. I'll provide descriptions of each.
FBM has many unique body kits and parts for a few guns like cockers, ions, imps, and spyders. They do specialty milling and anno upon request.
JCM and WWA
JCM is a small, possibly 1 man, company that does almost all of the above conversions and mods. They work in conjunction with WWA who supplies most of thier parts and components.
Alamo City PB
Another small company that specializes in delrin bolts for almost all markers, they are very high quality and can be custom milled upon request. This place makes the only aftermarket Black Magic bolts I've seen.
Home of the whiteboard and some top-notch airsmithing and milling services too. Send an e-mail his way and see if he can't do what you need.
These guys were on my red flag list for a while, but it looks like they're under new management, but with the same good stuff as before. If I hear any kind of complaints I'll re-flag them.
Yes another small company, Parts and a few milling jobs, but I'm not certain they still do conversions. They're located overseas so unless you're there you may have issues shipping to them.
An awsome company who sell "disruptors" they're own breed of fully modified halfblock. They also sell my personal favorite ram thats made by belsales specially for them, its basically a .44 magnum with the DP logo on it.
Warped Sportz LA
Used to sell the Z-force cocker however I don't see it on thire site anymore.
Anyone interested will like this site. It has many different jobs in it's gallery.
