I'm with MJ on his comment. I need my weapon to work, no questions. I will do stress tests on mine after they are out of the breakin period and see how they fare, except my concealed carry ofcourse.
I just want to make sure if i'm going to be in a situation where that gun needs to run day in and day out that it's gonna do it, deep cleaning or not. Its one of the reasons I want to update into a piston system on my next gun so I can get one to the point where the synthetic lube can do its work and not get all nasty from the DI system.
I don't use the MOE stuff, so I can't help you there I prefere the good quality free float rails to regular handguards in most PoUs.
