I was about to purchase a model1 upper in 300 whisper but now you've got me second guessing my decision. When I spoke to them on the phone they told me that their upper would cycle subsonic loads.

I'll have to talk to them again tommorrow, could you post the exact ammunition you used, any information on the box such as FPS or lot#?

I'll try to get them to tell me what ammo they use to testfire their uppers.
