POF Roller Cam upgrade kits
I am thinking about buying the POF-USA Roller Cam Pin .223 Upgrade Kit For AR-15/M16 Gas Impingement Rifles. Would you please share experiences you have had with them? I understand the way they are supposed to work, I am looking to answer stuff like:
How well do they hold up to things like Carbine courses that last all weekend?
What kind of life expectancy should I expect?

"Those who expect to reap the blessings of freedom, must, like men, undergo the fatigue of supporting it." - Founding Father Thomas Paine
