Brownells Gun Techs Steve Ostrem and Caleb Savant are back to help us separate fact from fiction. Or should we say "friction"? Today's topic is the PROPER way to lubricate an AR-15 bolt / carrier assembly. Turns out the Army Way isn't always right. When our guys were in basic training (a few years apart), what the Army told them to do was wrong. Well, Steve has theory that it served a purpose, but keeping the rifle running reliably wasn't it. Caleb shows us the metal-on-metal friction points where you actually need oil: the rails on the underside of the carrier, shiny wear points on top, and just a dab on the cam pin. How much oil should you use? The AR-15 is pretty forgiving on that point. Just keep it out of the combustion areas. Those little holes in the carrier are gas vent holes, NOT oil holes! Do BCGs with special coatings like Titanium Nitride or NP3 need to be lubed? The guys have some advice on that. What are your tips for lubricating an AR's BCG? Tell us in the comments below.

@Resistculturaldecline 9 месяцев назад

If its carbon fouled, the lubricant just thins the fouling to allow ease of movement. But carbon and oil also creates a lapping compound that increases wear. If its clean, itll run when dry and stay cleaner for longer. If its carbon gunked, it takes oil to restore ease of movement if cleaning isnt possible.

Good advice Long Shot. I usually have one handgun, a carbine and a shotty in "grab and go" status. These firearms are lubed on all contact points. If I take a gun out knowing I'll shoot it, I go a heavy on the lube. This further helps to reduce wear and tear and usually makes the gun a bit easier to clean.

@djinconroe 4 года назад

Every time I see something like this or find myself in a discussion about BCG lubrication I'm transported back to 1985 at Fort McClellan in Alabama. I see Drill Sgt Odom picking up a weapon that was malfunctioning on the firing range (those basic training M16's where older than dirt) and cracking it open, then giving it a literal enema of CLP out of one of those green bottles. Just hosed the BCG down and shoved it back in there with oil running out of the rifle. Didn't give that private anymore problems that day.

I have an external oil tank which feeds an oil line that runs directly into my gas block with a spring loaded valve. Each time the gas impingement system is cycled, the pressure pushes open the valve, allowing oil to circulate the entire action through the gas tube. The oil catch tank is inside the pistol grip. Once it reaches a certain level, the oil is forced back into the main tank for recirculating. Every 500 rounds I do an oil change and filter with 10w-40 full synthetic.

Tim at Military Arms Channel is testing the limits of a BCM build by not lubing it. He's up past 7000 rounds without a malfunction shooting it about a thousand rounds at a time with cooling time between mags. His hypothesis is that carbon can act as a dry lube and he'll get far more rounds without a malfunction than anyone else thinks. The idea that carbon COULD be a dry lube is valid as I once had a maintenance job at a college where we regularly lubed sticky door locks using a dry graphite powder, graphite being a form of carbon. However, the charcoal in your grill, the coal in a power plant, the graphite in your pencil, the graphite in a golf club, and the diamond in your ring are all carbon but with different functional properties due to the exact molecular structure and orientation. Which form comes out of burnt gun powder I don't know but I am interested to see how far Tim's BCM goes.

@MannyScoot 4 года назад

One of the first things I was told about oiling the M16/4 in boot camp that goes across all sister platforms is the fact that the platforms like to run wet. We were told that when in doubt, be liberal with the CLP we were issued. The type of lubricant is another subject entirely, but I recommend a liquid CLP for a couple of reasons. First is the fact that it does everything for you. It will actively prevent fouling and keep the fouling wet, negating the need for a designated cleaner. CLPs typically are designed to condition the metal, making it easier to clean with subsequent cleaning and lubrication cycles. You can also use grease in some parts of the rifle, that's another topic.

Even did it this way in the army.. moderate oil on those friction rails, light oil on the rest of the bcg, light oil on the gas rings (not through any holes, literally directly applied to the gas rings after making sure the end of each gas ring was pointed a different direction, before putting the bolt in the bcg), LIGHT oil on the part that resets the hammer - you never want oil getting on your ammo.. great way to increase chamber pressure and go boom instead of bang.

When I was a fresh recruit, I did whatever was told of me and trusted the NCOs. Fast forward to the end of my contract and I was very particular about what NCOs tried to do to _MY_ rifle. They wanted it DRIPPING wet with CLP and I refused, didn't get any reprimand for it. Dripping wet just didn't make sense to me, it was unnecessarily introducing the potential for schmoo and crud to habitate in the rifle.

I used the lubes and methods provided on issue gear but for my own AR builds, I treat the bolt and carrier cylinder like a piston drive on a motor, and lube the metal to metal areas with some high heat/ high friction grease like tetra. Other areas get a light coat to make it easier to clean later.

@thesaint1517 4 года назад

I had negative experience with dry bolts so I use a moderate coat of lube oil mainly in the surfaces you pointed out. However, a light spray of lube oil throughout the entire bolt seems to really work better. I don't clean my ARs every time I shoot them but I don't usually use more than 100 rounds at the range as others use much more than that. To me carbon removal is essential followed by a light coat of lube oil.

@herknorth8691 4 года назад

I use lithium grease on my ARs (and everything else, really). A thin film on the carrier rails, the cam pin, that raised surface on the bolt itself, and the rear of the locking lugs. The charging handle gets some too and any excess on my finger when I'm done gets smeared on the face of the hammer and into the detent groove on the takedown pin. If that's too hard to remember, then just shoot your rifle a bit and you'll start to see shiny areas where wear is occurring; put a very thin film of grease on those shiny spots and you'll probably be fine.

@damoncrowfeather4655 3 года назад

Eh I'm a grease guy, been using wheel bearing grease for over a decade now and never had an issue, never have had my bolt dry up when firing it and I go to the range sometimes 3-4 times between cleanings and fire about 200 rounds each time. When I finally go to clean my gun the grease is still where I left it. I use to use oil when I first got into shooting and instantly noticed at the end of my range session my gun would start to feel considerably more sluggish. Went to grease and never looked back.

@biggboysouth 4 года назад

Matthew Beaver I use lithium wheel bearing grease which has a thinner viscosity over some of the others. I live in FL so can’t say anything on cold (coldest it gets here is in the 30s) but the fact that we trust the same grease in our automobiles without ever giving it a second thought about maintaining for decades should say something about it’s effectiveness in all weather types. I did look up that same question years back and never found a definitive answer. Most just had the same concern you have but no concrete evidence. No expert but I always thought in extreme cold leaving the weapon dry was best since any lube would probably end up freezing.

I lube mine like an engine. Any area that touches another area that has movement during the cycle gets lube , other then rings. Rails on bolt carrier, hinge outer surface on extractor and pin. Shiny area in the middle of bolt where in makes contact with bolt carrier, ejection pin on bolt face, thin lube on all wings on bolt. Thin lube on cam pin. Any area that shows indication of friction- will be missing some finish or shiny metal gets lube . Inspect inside of lower after shooting session, if its bone dry at contact points then needs more or more often lube is how I run. In my experience after 240-300 rounds all oil is burned off or evaporated on the b.c.g rails and on the lower where rails mate. If two pieces of metal are rubbing during movement I say keep it wet .

@toki89666 4 года назад

Sounds good except the locking lugs, bolt face and ejector should be dry, otherwise you will introduce oil into the chamber which is unnecessary but also potentially hazardous and increase wear and tear by not allowing the case to properly obturate to the chamber walls for a good gas seal, Oil in the chamber will allow some of that gas to travel rearward onto the bolt face, hence the extra wear and tear, not to mention filth. Lube her all you want behind the locking lugs, forward of that should be bone dry.

I run as dry as I can to keep from prematurely gathering dust, I live in the High Desert in Eastern Oregon. Deployed 3 times as a Hawk Crew Chief. my rifles and pistols stayed dry and carbon free as much as possible but I used T25 or TU25 on my M240H. after the Marines gave us a bunch and we started using it, there is nothing better for belt fed. Its labeled for 50cal and up but I tell u what, its the best on a 240.

@MDR-hn2yz 4 года назад

TW-25 was probably the best weapon lubricant I ever used. I used on everything from 20MM, .50 Cal, M16A2 and M9. The grease was good for crew served weapons and the spray was great on personal weapons. I agree. When I went to Iraq, all of my weapons were run dry, and cleaned daily, at least. Never had a problem. Now that I am not in the desert, I have a wide array of lube and cleaning products to use. I still have some TW-25 floating around here somewhere.

Lubrication is important, but also look at the magazine as a potential cause for malfunction. The only time mine ever failed to function was while using a Promag. Never again will I use one.
