Low pressure tips for EM98:
1. A good non-ported 12in. barrel.(I suggest LAPCO)
2. PMI Pure Energy 2001 (Thor) Regulator.
3. LAPCO Dual adapter
4. Good high flow preset nitro tank.(Pure Energy or Crossfire seem to work realy well.)
When installing the regulator, screw the dual adapter where the tank would screw in. This is where the Rock reg. will go that runs the ram pressure. By running it this way, there is always a constant supply of air (800-850psi.) going to the Rock reg. The velocity of the gun now can be adjusted by the 2001 reg. Just make sure that the adjuster on the side of the gun is backed all the way out.
Newer 98's with the plastic power tubes will adjust as low as 300-350psi at around 285fps. If you have the older aluminum power tube, you can go as low as 250psi at 285fps.
250psi is where I run mine at right now.
