It reduces the volume.

Yeah. You are lopping off a big area in back that holds air and you need to plug it when you're done with the lopping.

I love my single - rod UC kit. Much lighter pump stroke than I remember from an over the barrel pump handle, but still small and light. A right - offset SC body feels pretty compact ; not sure but you might be able to get the aluminum one piece feed on it. 12 balls is just short enough to not hit me in the lens.

I am pretty sure the 12 round feed will work on an offset rf body. There'd be no issue with a lf.

Things I would suggest you don't do are cut the valve or mess with internals. Other then that the Kframe build and Spring feeds are very cool mods for the phantom. Keep in mind micro setups are less efficient and harder to aim but that don't make them any less fun to play with.
Chucky has this right. Other than aesthetics, there is no point in "bobbing" a Phantom valve. There are no noticeable performance gains, and the effort can often lead to simply wasting a good valve body. Remember that the part in question will be under extremely high pressure (in excess of 800 PSI - or higher depending on temperature and type of gas being used). A rookie milling mistake could result in a catastrophic failure of the part. One can easily see a grub screw turning into a projectile that will fly backwards into the face of the user.

The reason that there is confusion regarding if a bobbed valve reduces volume or not is because there are two ways it's been done - cutting into the chamber, and cutting off the excess aluminum material while maintaining the factory valve chamber size.

Cutting off the excess aluminum material while maintaining the factory valve chamber requires exact measurements. If there isn't enough material left between the valve wall and the cut, then you run into a potential safety issue with high pressure blowing out a thin aluminum wall. I have no idea how thick the aluminum wall needs to be in order to safely contain high-pressure gas, but have to assume CCI/RTR, Nelson, Carter, etc. made the walls on their valve bodies thick for a reason.

If you cut into the valve chamber in order to achieve "devolumazation" (again, a theory that has yet to yield any proven, documented results based on the simple fact that the properties of CO2 are effected by a multitude of independent variables), you will need to compensate for the distance by cutting down your valve spring size, and also may negatively effect the cup seal/valve tube travel. Phantom users who have had success with this probably spent quite a bit of time getting it right, or have been very lucky.

Seems like every season I read about how someone wants to mod their Phantom in an effort to make it look cool. Hey, I like a cool-looking Phantom as much as the next guy, and always appreciate ingenuity when it comes to mods as there are some really decent ones out there. However, it's important to ask yourself two important questions before hacking up what you have...

1) If you're considering making a performance mod, why hasn't CCI already made it?

2) If you're considering making an aesthetics mod, how will it effect the performance, safety and simplicity of maintaining the gun?

Most of the aesthetic mods I see end up complicating disassembly and reassembly (gas-through-grips, under cocking kits, "Buzzard" side-slotting, etc.), and end up providing zero performance gains. Just some things to consider before breaking out the Dremel and drill bits.

You can cut the valve down fairly close to the back of the frame and have no impact on the place where the spring is seated. Just less space for air in the valve. The dropout valve shows you how much room you need (at minimum) and add thickness for having enough meat for your plug or gauge.

Obviously when modifying paintball guns just like chairs and stools care needs to be taken not to make the object in question dangerous as a result of shotty work.

There are some good performance mods, but they're mostly adaptions to modern sensibilities. ASP detents or a freak kit to deal with tiny paint for example.

I like my UC kit, but that's because I am an ogre with hamfists and it's easier to grab.
