"Have run this for about 40 hours worth of game time and love it. I even flat hopped it and it and it still gives me good shot consistency.

"As others have said, the purple is the way to go for most guns. If you're running an LMG and only use full auto the red is the better option as it will last much longer. I have used the purple bucking on various Prometheus 6.03 inner barrels as well as ORGA MAGNUS inner barrels and have never had an issue. These buckings work with Maxx ME pro hopups, prowin hopups and G&G rotary hopups from my personal experience. Your experiences may vary.
