The other night I spoke with my friend, Brother Kenny. Brother Kenny is an extremely skilled armorer and M16 expert. He works at a government arsenal. ( Sorry, but I cannot say which one )
Anyhow, Brother Kenny reported on a new kind of bore cleaner. It is called Wipe Out. This stuff is the best bore cleaner that Brother Kenny has ever tried. It completely cleaned a number of worn out barrels at his armory. He just squirted some Wipe Out down the bores and then let everything sit during lunch. After lunch the rifles were perfectly clean. He even tested the stuff on worn out match rifles. And after cleaning, these "worn out" barrels shot fine groups once more.
Brother Kenny also advises that recent M4 and M-16A2 production from both Colt and FN feature over torqued barrel nuts. He has seen barrel nuts torqued to 80 foot pounds. This is far too tight. Instead of going nuts with a torque wrench, just tighten the barrel nut snugly using a DPMS barrel wrench.
For best accuracy in an AR-15, you merely want the barrel nut to be tightened a little tighter than snug. If you tighten it too tight, you can run out of windage.
So beware the torque Nazis.
