You put it in the pistol location didn't you? I think it works with a .125 in the CAR location and from what I've seen elsewere around .085 works for the pistol location.

Mine is .120 on a model one 16 inch barrel with an adjustable gas tube. I shoot mostly 150 gn bullets at 1050fps. Works without any malfunctions.

Nope,
I heat shrunk a SS sleeve around the pistol gas port and drilled another hole up at the front sight mount. I do have to offer a correction however. The barrel is not a 300whisper, but a wildcat that I've been working on. It is a .308 in bullet dia and 150gr weight. I'm able to reach 2,280fps out of this 16" barrel.
