I am new to the ar and was wondering what kind of lubricant i should use on the bcg.
I’m not an expert, but I know that this doesn’t have to be a difficult choice. Anything that provides lubricity and stays where you put it will work. The most important parts to lube are the bolt, the cam pin and any of the “shiny” surfaces on the BCG. Lubing the whole thing won’t hurt of course.
I don’t like Breakfree CLP because it evaporates even when the gun is not being used.
Edit: I’m assuming you are looking at using some type of oil. Some people like grease, but I’ve never tried that.
try Silp2000, I have been using it for about 6 months and It works great, they say its good for 1000 rounds before you need to re apply but I do it every 250-300. its really thick and stays in place unlike breakfree CLP, but like the other guy said, anything that lubricates will work
Mobil 1
Mpro7 seems to work good…
we haven’t had a good lube fight in a while… this oughtta be fun.
i’m currently using Mobile 1 0w20 to lube after cleaning… heavy application to all interior metal parts, wipe with oily rag to outside steel parts.
i then re-lube during firing with a mix of 0w20 and PB Blaster penetrating oil. it relubes and helps break up the mud.
just what i’m currently doing… i change my lube types and methods about every 6 months, it seems… and my guns always run. so in other words- just make sure it’s oil, and it’s wet.
ETA- the only stuff i’ve found to be detrimental to function is thick oil additives, like Hyperlube… thought i’d be smart and add some of that to a batch a made a while ago… seemed like it would add some sticky viscosity, but all it did was turn into paste in the gun.
I clean and lube everything i own with BreakFree CLP… Appears to be working well so far and stays where i put it. Next will be FP10, Heard it is a little thicker which CLP wouldent hurt to be a tad bit thicker
I use FP-10. Liberal application on the BCG. Somewhat high viscosity (the thicker the oil, the longer it will last on the weapon) and it doesn’t evaporate.
I have heard good things about Mobil 1. I use machine gunners lube. I did not have to buy it. LaRue Tactical always gives it to me in orders. I even have gotten a big bottle of it and not just those little ones. I use breakfree clp also . . .
Mobil 1 synth 5w-20w same oil I use in the truck, same in my wifes car I even put the stuff in the lawn mower if it needs it.
I use Slip 2000 EWL and Larue Machinegun Lube on my AR’s and handguns, and clean with M PRO 7.
first i tried REM oil…evaporated like crazy when it was stored, would come home off tour to a bone-dry BCG. just wasnt consistent.
Machine Gunners lube… nice n thick, works pretty good. big fan.
now i currently i drench my BCG in break free-clp. been great so, far, does evaporate after sitting a while like some of you stated. not near as bad as the rem oil tho.
think i might try the mobil 1 trick. lots of good talk about it. and cheap!
Just about any oil will work. You just have to make sure you apply more as it gets burned off.
I use SLIP EWL because it doesn’t burn off as fast as CLP. I use CLP on a rag to wipe the exterior off with because it has better corrosion resistance than EWL.
I think Im going to try Mobil 1 just because its cheap for as little as you go through it. One bottle of EWL will buy you 2 quarts of Mobile 1, and a quart will last you 20 years. I use Mobile 1 for our cars anyways so I always have it sitting around.
mobile 1 for gun lube. Cheap and wet. All day.
Slip EWL, Weapons Shield, any synthetic motor oil will do. I prefer Royal Purple.
WallyWorld synthetic 5W-30. Has worked well in high round count classes for both pistol and carbine. Cheap.
SLiP2000, Machine Gunner’s Lube, CLP, Mobil One, Weapons Shield, and various other engine oils with lower viscosities will work. The differences will lie in how often they have to be applied. Some swear by grease but it would seem(and I haven’t tested it) that it would hold onto dirt and other particulate matter more than an oil. Maybe we can get IraqG to weigh in on what has worked in the sandbox(in large scale application).

I started using KG-4 about 2000 rounds ago and I’ve noticed it lasts way longer than CLP. I’ve got about 1400 rounds without cleaning or a failure only lubing with KG-4. I lube about every 250-350 rounds but have gone as long as 500.
KG-4 keeps the gun wet for about 400-500 rounds. I don’t do relentless mag dumps but I probably do 30-round mags in <2 minutes 7 or 8 times out of 500 rounds. For a majority of the time, I shoot 10-round groups in about 1 minute. So, I get the gun “hot” enough to smoke several times an outing and the KG-4 seems to stay in place and keep it running.
imho, I think as long as a quality AR is lubed (wet) it will work. Some lubes last longer than others, you just need to find out how long your lube lasts and make sure you’re keeping your gun “wet”.

Used to be the main topic of discussion here. Could have called this site M4lubrication.com/
Blackjack,
Welcome to the forum.
Not to be an ass or anything, but do read around here a good bit. There are quite a few threads on this topic.
Here’s a helpful article by Larry Vickers on Weapon Lubrication.
The general concensus is more is better.
I have used Breakfree, RemOil, MiliTec, M-Pro 7, Slip2000 and SlipEWL, and Weapon Shield.
My current favorites are Slip EWL and WeaponShield. For me WeaponShield stays in place a little better but the Slip is easier to find.
I personally recommend Slip2000 and Weaponshield. Both have worked well for me. I also used FP-10 in a previous life.
