Here is the Ultimate Upgrade FAQ as requested by many. *I'll have to post the links to site and reviews when i get time, sorry -Crazyweasel*
Trigger Frames
Yay, I get to make my own section, hot dawg - Crazyweasel
* Zenitram Z-Grip- A grip with an angle to it. It's suppose to give a more natural feel to holding the gun, and I'm very sure it also is magnetically enhanced. Mainly preference like the OTB Frame.
* Greg's Mag Mod- Send you're gun to Greg at ICD, and have him do a magnetic trigger job for your gun. I believe cost is $65 but I'm not sure.
* Zenitram 45* Magnetic Trigger Frame - Same as Greg's mod only it comes as a whole fram, not a mod.
* Off The Break 90* Frame - A 90* frame similar to those on Angels. It comes with a short pull that is also magnetically enhanced. Mainly preference, but I've heard it's easier to acheive higher rates of fire.
High Pressure Regulators (HPR)
* CP Regulator-A great regulator for its price and works extremely well! Fits on BKOs Review-
* MacDev Gladiator-One of the best regulators on the market and the choice of many. Fits on BKOs with a little bit of hoaxing.
* DYE Hyper Regulator-Practically a Gladiator copy and is $40 more and CLAIMS to be Titanium when it is actually Aluminum. Does not fit on BKOs.
* AKA Sidewinder-A very nice regulator and the choice of many. The middle size (4 inch) works best.
* Bob Long Torpedo-A competitively priced regulator but does not work as well as the other higher end regs. Fits on BKOs.
* Air America Vigilante/Messiah- A good, stable regulator. Not positive if it fits on BKOs.
* Palmer Stabilizer-A positively awesome regulator with the quality that Glen Palmer always put into his products. The BEST regulator for CO2 (if you would like to use CO2, it is best to get the Male and Female Stabilizers to run on your gun) Fits on BKOs.
HPR ASA Adaptors
* Zenitram BKO ASA for Cocker LPR-A great ASA adaptor because it allows you to use an Autococker LPR on a BKO.
* Zenitram 15* ASA Adapter-The one and only angled ASA for the Bushmaster. Gives it a fresh new look and makes it look like a totally different gun along with the Z grip.
* Check IT ASA-A quality ASA with two guage ports so that you can have the guage on either side.
* MacDev ASA-A longer ASA so that the air can expand.
* Lapco ASA Adapter-Different in the fact that it does not have a guage port and is in the shape of an L.
Low Pressure Regulators (LPR)
* Vaporwork FMD with Rock- this is the type of upgraded LPR you get from the Vaporworks package, and now come hoseless. They are considered to be just as good as Sonics, and Vice versa.
* Zenitram Autococker LPR Adaptor-A $35 adaptor that allows you to use ANY Autococker LPR on your Bushmaster.
* Vaporworks Autococker LPR Adaptor-Same as the Zenitram and the price is within a dollar of the Zenitram.
* MacDev Sonic LPR-A solid regulator from MacDev and is a bargain considering that it comes with an LPR guage for the price of the Autococker LPR package.
* ShockTech LPR Plunger-A valuable upgrade if you are considering keeping your stock LPR.
Valves

Most valves work about the same. Here is some in-depth info from Sho otpaint:
Quote:
I am not bias.
I have tested four different valves at this point.
Vapor
Red
Stock
My own valve.
With the red valve you will see about 10-20 FPS increase over the stock valve. Only down side to the red valve is the stem. I had to replace the stem on my red valve because it some got bent under normal use.
With the Vapor valve installed I saw about 15-25 FPS increase over the stock valve. In direct comparison to the Red valve I saw a 5-10 FPS increase with the Vapor valve. Nice thing about the Vapor Valve is the lifetime no leak gurantee on the cup seal!!!
After getting bored one night I took a stock valve and started moding it. By lopping off the top half of the valve I saw a increase of 10 FPS. By cutting a new cupseal I saw another 5FPS increase, the cupseal had a convex cut on it to help channel the air into the valve more readily. I then cut a oring groove on the stem of the valve. This yield another 4-5FPS. With this information in hand I went to making a valve of my own design.
The valve I created consisted of a ramped air passage inside of the valve. It was a stepped ramp similar to ramps used in the ports of an automobile.
Next we undercut the area between the orings.
Next we removed the top half of the valve between the orings.
The input of the valve was opened, dont remember exact measurments, to .500.
Then we cut a new cupseal with the cone shaped seal going into the valve.
Final project was cutting a new stem for the cupseal to sit on. We cut the stem down in the area that would be inside of the valve when it was open as well as added an oring to seal the back of the valve when the valve was opened.
After all this work we saw about a 25-30 fps increase in velocity. Our biggest problem was making the valve seal. We had repeated problems with it sealing.
So unless you want to put a lot of time into it and make your own I would recommend the Vapor Valve. It showed the biggest increase in FPS with our markers over any other valve that we have tested.

Rams
* Solenoid Pressure (SP) Modded Ram-The SP mod is an innovation in electronic markers. It is the Level 10 of bushmasters because it reduces the solenoid pressure so that if a ball gets stuck in the breach, the bolt will bounce off of it instead of chopping it. Only for BKO's i believe.
Bolts
* OTB Blind Bolt- A bolt with a rubber like tip that is supposed to bounce off balls and eliminate chops. Also made to eliminate blowback. No "hardcore" reviews out yet.
* Z-4 Bonebreak Bolt- A new bolt by Dan Bonebreak. Claimed to eliminate blowback and be made by a slick material, although I haven't read many reviews.
* Vaporworks Vapor Bolt-A reliable O-ringed bolt from Vaporworks. THE bolt to get if you have blowback problems.
* Tantrum Bolt-A little bit pricey and not worth the money when other bolts are have the price.
* Shocktech Stubby Bolt-A nice bolt but is so short that you need to use a straight shot to field strip it.
