WDP Angel Angel 1
70/4500 Nitro Duck iReg HPA Tank set to 600psi
iReg Piston Kit
Easily adjustable output pressure.
Slightly large reg tip (ND is working on it).
As an Angel 1 owner, I know that the optimum HPA output pressure into the Angel 1 is between 450 and 650psi. This is due to the internal vast volume of the Angel 1. According to the WDP Master Techs, if you go below or above that your Angel 1 will not work to it's fullest potential.
I checked my what my trusty 70/4500 LP Crossfire (CF) was preset to and found that it was preset to 420psi. I was bummed because I wanted my Angel 1 to have zero problems. True, I have played with the CF on my Angel 1 without issues but I wanted a slightly higher pressure as a little extra insurance. I didn't want to get an adjustable HPA tank because I really wanted to keep my screw in tank ability. I tried contacting CF several times to see if I could send in my CF reg to get it preset to a higher pressure but I did not get a response from CF. So, I decided to check out what was new on the market and came across the new Nitro Duck iReg.
To be completely honest, I've read reviews that state the Nitro Duck regs are horrible, that they suck, they do not recharge fast enough for higher end electros, etc... So I was concerned about dropping down the cash for something that I didn't have "a good feeling about".
So, I contacted Nitro Duck with my concerns and received an immediate response stating that they stand 100% behind their products and customers. That was good enough for me so I decided to purchase one and give it a chance on my Angel 1.
I found that I had to slightly back off the Angel 1's ASA on the built in Angel rail because the iReg's tip is slightly large and if the Angel 1's ASA is not brought back some, it will screw up against the grip frame. This is not really a big deal and moving the ASA is easy and safe to do. It only has to go back slightly to allow the iReg to screw into the ASA completely.
I also purchased the piston kit because the iReg comes stock with the 800psi piston. The piston kit comes with a 400psi, 600psi, and 1,000psi piston kit. This allows you to easily change your iReg's output pressure. All you need to do is empty the tank, unscrew the holding screws and screw off the iReg cap. The piston is easily removed and replaced with the piston of your liking once you grease the piston's o-rings with Dow 33 grease. Reassemble the iReg and you are good to go.
I found that the output pressure was 650psi and that was slightly higher than the 600psi that the piston is rated for. This again was not a big deal because everything is slightly different and I know that from working with Angel regs (specifically the WDP LPRs), number of shims you need to get a desired pressure if different from gun to gun and I imagine the same goes for the piston.
I shot just about 3 cases of paint through the Angel 1 using the iReg without a single issue. I used every mode possible at the chrono to see if the iReg would starve the Angel 1. It did not. I experienced no shoot-down or any other problems. My velocity variance at the chrono was consistent with when I use the Crossfire.
Needless to say I was EXTREMELY HAPPY with the iReg.
As far as the large tip, Nitro Duck says the newer tips that are out soon will have a smaller tip. The larger tip fits almost every ASA right now but they have noticed that most people want a slightly smaller tip so they are coming out with that.
Also, the iReg is not long as most people think. In fact it is slightly shorter than the LP Crossfire reg.
I would recommened the Nitro Duck iReg. Excellent product and even better customer support.
