New Custom Upper with Superlative Arms Piston System

[Double Naught Spy]

After three nights of hunting and 16 or 17 suppressed rounds fired with the magazine being topped off to stay full, I am pleased to say that I am not seeing near the nastiness that I would normally see deposited on the remaining rounds of the magazine. Usually what I see at the bottom of the magazine are rounds with blackened deposits, some of which are not just seen, but felt as raised areas, plus blotchy discoloration of the brass (corrosion?). In the past, I would use steel wool or a brillo pad to clean these last remaining rounds between hunts so that they would feed better. Here is a pic of the magazine after the hunt was over. You can see that there are still some white/gray deposits on the brass, but the brass is not discolored. If I was to assign a numeric value to the difference in how much better the brass looks, I would have to say that it looks 50-70% better that with not using a piston system on a suppressed rifle. If you think the use of numbers is to quantify something that is only qualifiable, I understand. I would then say that the rounds in the mag look substantially less deteriorated after using a piston system on a suppressed rifle over direct impingement on a suppressed rifle.[ATTACH=CONFIG]9863[/ATTACH]
