Model 1 Sales 300 whisper upper function problems

[jripper]

Glad to here your upper is running well. Mine is also, altough a few weeks ago, a friend came over, and we went to try it out, and I got failure to feed/extract short stroking again, sub sonic or super sonic. When I pulled ou t my bolt, I found that the carrier key had come loose. I then noticed that the "staking" on the model 1 bolt did not even touch the allen screws. I put red loc tite on them, and staked them a little deeper, and it all works again.

Just something to check if you are using a model 1.

Thanks everyone here for their help, as I don't think I could have gotten it going without the input here

I finally chronographed my 11.0 AA 1680 and 220 sierra load. Out of my 16" M1S ar, 3 shots averages 980, with a high of 1020 and a low of 933.

Only did three, as that was all I had on hand, and it was starting to rain.
