Guys,
Here's the gig from the angle I deal with for a living.
Disagree all ya want, agree all ya want.
If it helps great and I'm glad to have helped if not.... it's good to know whatever ya got is working for you.
Barrel extensions catch and hold crud.
That crud causes bolt lug wear and friction.
Bolt lugs are thrust back against extension lugs on firing at tremendus pressure.
Ya gotta keep 'em clean.
Well....reasonably clean.
They will work just fine while a bit dirty, and will do their thing under adverse conditions.
But why beat the hell out of them when you don't have to?
The Military chamber brush is GREAT for getting the carbon and gunk loose.
My guys like to mix Diet Coke, Coffee with Creamer and pizza sauce in there.
Trust me, I LOVE the Military chamber brush and wear the hell out of them.
From there ya gotta get the loosened crap out.
Q-tip Yoga is one thing, Once upon a time I did the same as a simple Jarhead...it took hours.
Screw that!!!!!
Run the Military chamber brush and your favorite solvent.Work it around real good.Make that Brush earn it's .79 cents worth.
Then use a lug tool and get the crap out.
Sinclair makes a BRILLIANT lug tool!!!!!
The stupid thing is a work of art.
But to be Bone simple.......and CHEAP.
Look in the Midway catalog.
"Action/Chamber cleaning tool set"
Part# 109-658 3v83n3
For the whopping sum of $12.26
Get extra swabs.
Been using the same tool for 3 years and it's doing wonderfull.
If you are really cheap(Like me..), wash the swabs in Isopropyl alcohol when done and make them work for 3 or 4 times each.
Adding extra lube,FP-10,CLP, Moose milk/Mouse milk/Yak splooge, just creates a situation where carbon and other crap gets stuck in that area.
Use a thin, light coat in the extension and when done remove the gorp.
Most folks are absolutely SHOCKED at the amount of crud in the barrel extensions of their rifles when it is removed for the first time.
Carbon and crud holds moisture.
Moisture freezes, causes rust, and bad dreams of former drill instructors chasing you through fields of Q-tips.
The best part?
It takes but 30 seconds to get the crap out using a cheap tool.
Just my .02.
Do what ya gotta do.
