AR bolt & carrier ?

Militec has worked well for me.

Do you buy into the whole "get the gun hot so it bonds" thing with the militec?

Yes, actually....I do. But I don't "get the gun hot" by firing it.

I use Militec on my AR only (bolt, carrier and trigger sear). You can use a hair dryer to heat the parts for the initial application(s). After that...I use it mainly for a wet lube (use sparingly).

I don't clean the bolt or carrier with harsh solvents either (Carb/Brake cleaner), instead...I use Mineral Spirits, an old tooth brush and compressed air. The lubricating properties seem to have stayed in place.

Honestly, I think the "burnishing" effect of the action cycling (parts against parts) does more to embed the lubricant than anything else. But MT does make a noticeable difference in smoothness... and parts clean-up is definitely easier.

Ok - the science seemed sound but I wanted to check around. Why only use it on the AR?

No limiting factor, its just the bolt and carrier of an AR are ideally suited to such a product. You can use it on any reciprocating/sliding/moving part.

I am sold on Wilson's Ultima-Lube for a gun grease and use it on the slide rails of my S/A's. They are cleaned frequently and I use very harsh solvents on them.

You can use the Militec anywhere you like (even the bore of a weapon), I just chose to use IT on my AR and other conventional lubricants on my other firearms (shotguns, revolvers, slide rails on S/A's).

I have one AR that will run dry. I use a light film of RemOil on it because that's all it needs. I have another AR that doesn't run very well unless wet. I use a little motor oil on it and it works fine.

I went to the range the other day and forgot my oil. No one else there so I was kinda stuck. Ran the AR for about 40 rounds and it starting jamming. So with no other option I started spitting on the BCG. I ran about 50 rounds on just spit!!

Wish I'd known that when I still had my St. Bernard. I could have bottled and sold all that slobber.

+1 for my Great Danes.

I use Castrol 5W-30 full syn. on my AR. I just dip a Q-tip and rub the BCG rails, slide it into the upper and rack it few times.
