I just happen to have recent personal experience with this. I have a Tippmann 98 Custom and just bought a Female Palmer Stabilizer. With the ring mount and mini drop forward, it ended up costing me $130. I think it was a good buy for me for the following reason. The short answer reason is that I am now more accurate and I do not shoot hot. Long explanation; With CO2 as has already been mentioned in here, your pressure will change with temperature. So a tank close to 60 degrees may be putting out 700psi, but put out 900 close to 70 degrees. What will happen with that pressure increase on an unregulated gun is that your velocity will jump. In my case, I chroned my gun at 280fps. 2 hours later I rechroned and I was at 310fps. BAD surprise. With a regulator, the pressure entering your valve is always the same provided your tank meets or exceeds the pressure the regulator delivers. Net result will still loose velocity as I run out of gas in my tank. But I will not be running a hot gun anymore. The second advantage is that with a regulator the velocity between shots is more consistent. In my case, the last 10 shot chron I ran before getting the Stabilizer showed velocities running from 266 to 284. On my last chron WITH the Stabilizer, my range was 277 to 285. This is with a 12" Teardrop barrel running on CO2 and PMI Big Ball paint. Also at about 30 yards, my shot cluster went from about 24" to about 15" (not measured by tape ruler!!! These are approximate!). The improvement came because my paint was grouped together on the drop/verticle. In other words, before the regulator, my shot clusters were oval as some paint went straight others drop quicker. Now my shot clusters are more round in shape. One last note. Some people (including here) will say that regulators should be used for HPA system and don't worry about it for CO2. Regulators ARE less effective for CO2 than compressed air because C02 guns need higher pressure to run. But there IS an effect. If you're going to do it, it's best to get one specifically designed for CO2 (like Palmers and Bob Longs). Knowing your velocity is consistent is helpfull during the game, and I argue it's an safety issue since CO2 tends to spike to running hot. Gaining accuracy is good at any time. The real question is how much of a problem are you having with velocity spikes and accuracy, and how much money are you willing to spend to fix it? : I have a 23 degrees botton line regulator, the ones that are on the rebel extremes. I move the adjustment screw in and out and the pressure gauge doesn't move. Does anyone know how to adjuts a regulator properly?
