Thank you very much PSP. That is exactly what I am looking for. Now I will start, carefully, following the instructions. I'm happy!
Bill, I tried mine with 24 rounds of Fiocchi FMJ, 6 rounds per magazine. Not a glitch and great precision for a mini-gun. I am aware of what you said about malfunctions, but mine is an American Arms made. Maybe that makes a difference.
Thank you all for your invaluable help.
