Umarex Guantlet SL 25 issue?

[Powerstroke]

Everytime I begin to shoot, fresh magazine, first 2 shots are off all target. About one inch high and right. The rest are all right on target? I have a 2200psi regulator with a Buck Rail Modular Suppressor. Shoots 25.39gr. AEA's at 975fps.

Have you tried the first couple without the mag? If it's after the gun has sit for a while could be reg creep and the first few are shooting hot.

Doesn't matter which magazine. Big Air, stock or Maple Custom single loader. First 2 are off target.
