AR15 owners: Please remember to lube your BCG!

[andy t]

I was at a range with a friend that was having trouble with his AR while using Wolf ammo. After a few magazines, there would be failure to feed. I tried some of the basic diagnostick steps, and since he mentioned he had an RRA BCG, I decided to pull it out to check the staking. When we opened the rifle, the BCG was bone dry! I guess hanging out on M4carbine.net for a while, I assume that everyone with an AR knows they like to be wet, however, my friend didn't. After I lubricated the BCG and bolt lugs, his rifle ran like a champ.

+1! It's probably the most important thing to maintain with an AR for reliability. Keep it wet.

What is a good lube to use? I don't remember what I use, but I usually use a lot of it.

 

[Hanwei]

Break-Free CLP

 

[MassMark]

Militec-1

 

[kristo]

you don't have to take it out to lube it. use the two vertically stacked holes in the recessed area of the bolt carrier.

Militech-1 is king.

Taking the BCG out of the gun, and coating it with the oil works ALLOT better. It gets the lube on every contact point. Internals too.

I use Millitech, although Pat Rogers in his article, mentioned the use of Vagisil - don't laugh, it worked!

Sounds to me like his rifle may have had "other" problems.

I put together an A2-length AR and have run it completely dry for the first 800 or so rounds, using Wolf ammo mostly (a little Prvi, a little Brown Bear), no cleaning whatsoever, and have had no FTFs or FTEs. Sure, that's not many rounds, but I would have no qualms about running it dry for a while.

vellnueve,

It's great that your rifle worked for you, but I would not recommend anyone to run it dry on purpose. A dirty AR will run as long as it's lubed. A few drops of your favorite concoction will go a long way towards a reliable rifle.

I've had the BCG in my AR's coated with a very-low-friction coating, in one case Black Teflon, and in the other an Electroless Nickel/Boron Nitride process called Cera-Plate. Both feel like they're going to squirt out of your hand as you're holding them, and greatly reduce the need to run as "wet."

my brother is in the 101st and he says a lot of guys usually run their rifles dry over in the desert. Maybe it has something to do with moisture collecting sand?

I'm going to lube mine when it comes in

just a side-comment.

I store mine dry, and lube it before the range.

Exactly! Sounds to me like he needs an H buffer and or stop using wolf. My buddy has Stag that will not run for shit and he refuses to listen to me when I tell him he needs a H buffer.

Also the best way to know if you are using enough lube is "if your bolt looks like you dropped it into a bucket of lube, then you have enough".

I use the synthetic Militec1 on everything. The more you use it, the more the molecular lubricant gets into the "pores" of the metals in any gun. That happens when the gun warms up.

Militec1 is better than CLP in that when it "dries" it doesn't get STICKY. It's why the grunts in the field (especially in sandy areas.... say, "DESERT") have switched to Militec1. Their jamming issues have all but gone away completely.

I run a swab of Militec1 down the barrel, and then wipe out excess, and have found that the lube has penetrated the barrel lining, and absolutely keeps it from fouling. Hundreds of rounds, and the gun is very easy to clean!

I use Mpro-7 oil on my BCG and it works great. I've never had a lube related jam on my Colt. The only time the rifle ever jammed was with a
couple of -really- shitty magazines.

Anyone use hoppes oil on their BCG? Or is that a nono?

 

[DukeInFlorida]

I wouldn't use Hoppes oil for anything.

I like their cleaning solution, but would never use their oil.

Get some real lubricant: Militec-1
