Part 2.
As far as ammo goes, I reloaded with 10.9 gr. of AA 1680, using 220 gr.Sierra MK's and processed brass purchased for Mr. Davis that we know from this board. I have not encountered any problem what so ever using this load. It chronographed at an avg. of 1055 fps with no signs of over pressure and cycling was perfect with and without supressor attached. Accuracy was well under 1 moa. I have not tried using any super sonic loads to date, but I feel that this should not be any problem. I will say that you will probably want to use one of the gas buster charging handles on your AR. These are a little pricey but they do work well in keeping the tiny powder particles off of your face, especially when using the supressor.
I want to say that it took some hours of trial and error to get to this point. So if you are having problems getting your AR running, don't give up. I believe your patience will pay off and you will be rewarded with a wonderful shooting experience, as I have. Let me know if I can be of any assistance to any of you. And thanks again for this forum and all the fine contributors.
Happy shooting! Al Sheffer
