6 ARC. Gas Gun. Bolt carrier group

[troupe]

I have been using Brian Enos - Slide Glide, along with Don Fraley's - Advanced Weapons Technology for years.

 

[Retired shooter]

Last trip to range for load development, bolt carrier group lubed with the TW25B. Not a big quantity of rounds fired, everything worked, and functioned well. Nothing extremely dirty , lube still in place , not gummed up, cleaned BCG with citrus based spray cleaner, wiped of dirt ,and carbon, very easily.

Impressed at this point.

Have a great 4th of July.!

She's just going to be a dirty girl but she cleans up nice. TW25 is a very good MG grease and the twin to it is Lubriplate white grease in a small tub. I shoot mostly suppressed and am well used to the blackness as it's just part of it. The bigger issue is if a lube (oil or grease) wipes off easily and keeps the fouling in suspension during cleaning.

FWIW I will use the Lubriplate mentioned (don't remember the part #) and it is more or less TW25 grease and also CRC Silaramic (a synthetic brake grease a little heavier than the two mentioned above) which is also a good one. They all provide great lubrication.

Thank you.
Are you referring to the white bearing grease we used years ago hand packing wheel bearings. May even have a can lurking in the back of a cabinet. Would think that would be to thick.

May check out the Crc silarmic, will need to use what we have before buying anything else.

Thank you.

Lubriplate SFL-0 is the one I am referring to. It was designed as a lubricant for food service machines and it is most definitely not a bearing grease. That being said, I'm not licking a bolt coated with it. It comes in a 15oz tub and may last forever. The CRC Silaramic I use on bolts and pins for brakes and saw reference to it being used for bolt carrier groups and thought why not. Both work great as a lubricant and helps keep the carbon suspended and easy to wipe clean in an upper. Heck, a good oil works well as a lubricant but doesn't like to stay put. The lighter greases do both.

Many of us who shoot these things suppressed exclusively (or almost exclusively) remember the fine times cleaning an unsuppressed AR. Them dirty girls make you look for an easier way. You know, I may have found the secret to good relationships (a good quality light grease).

My shooting partner always compared AR's to Las Vegas prostitutes. He would say that no matter how much money you spent on them, they would always break your heart. We both come from a benchrest background (boltguns, truck axle barrels, benchrest style stocks, and known easy to tune calibers) and AR's don't play by those rules.

I can still remember being young and my grandfather telling me grease is cheap, parts are expensive. If one of my rifles break, it's not because of lack of lubrication.

Trip to range Fri. morning testing powder and different bullet brands. First trip with only one powder CFE 223 will be able to see how dirty that one is. Will be cleaning it today.
Have a great day.!

Let us know how the CFE powder worked for you please.

You're AR's don't play by benchrest rifle rules however when you use them as general purpose (CQB/hunting) they outperform nearly everything else.

Thank you Sir
I have a can of the Permatex silicon brake grease, after the truck brake repair a year ago. Never thought about firearm lube. Never made it to Vegas so would not know about the other part of the story, however I have always believed in well lubed equipment especially for what pieces and parts sell for today.

I can say that the CFE was not really dirty, however I did not run an excessive amount of rounds, as I was only testing, and doing load development. I do have some Berger Hunter Elite 108s loaded to max grains, CFE 223 along with some Hornady 110 A tips loaded to max.

Dont remember what the powder specific was but fired some Sierra 107 match kings last trip. First three out the cold , just cleaned barrel with a Magneto speed bayonet on impressive group and decent velocity.
Told my son I may just use the bayonet as a tuner.

May slow down on testing, son and I converting some equipment, and processes, looking for more consistent neck tension .

Everyone have a great day

Let us know how the CFE powder worked for you please.

You inquired about 108 Bergers with CFE 223, here are my results

Now I would ask any of the more experienced RSG types that reads this thread, for suggestions to get the ES lower.

Thanks. & Have
A great day.!

Stupid video.

I use bacon grease.... Not safe for consumption.

 

[LVLAaron]

CFE223 is a filthy powder...

Any chance it's way over gassed?

 

[Retired shooter]

Upper assy. built by a credible builder. Only problem I have had is bolt carrier group does not always lock open. Sent it back to him he has worked on it again, Have attempted to remove gas block to check gas port and tube. May have to use heat gun as set screws are extremely tight. Worried about stripping them out. Thinking he may have used Loctite.

Experimenting with different lubes, found some that works well, and easily cleans everything back up.

Starting to think my go to powder will be Leverevolution.

Have a great weekend guys.!

I use Hobo Oil on my AR bolts - 5.56, 204 Ruger, 6.5 Grendel, 6mm ARC. Not to the point of dripping off, but a good coverage dose. I have not had any functional issues firing up to 200 rounds in a session without in-session cleaning.

It works for me and how I shoot, but ymmv

Several years ago, I bought a tube of Mobil 1 synthetic grease, a quart of Mobil 1 20-50 synthetic oil, and combined them together in about a 50/50 mix.

I slobber it all over every moving part in the AR......

You might consider M1 0W40 European Formula Synthetic motor oil and grease of your choice. It will give just as good anti-wear but also some cold weather performance should you need that. If you do live some place cold mix it until it is about the same consistency as US ARMY LSA was. If you live is Arizona make it thicker.

On a new semi-auto I run M1 0W40 plain until it has some break-in wear. Then I switch over to the M1 and grease mix. This way parts break in and fit nicely in short order and then the M1 oil and grease mix functionally brings wear and tear to a halt for all practical purposes.

I have been using M1 oil since around 1998 at least on all firearms blued and stainless with no issues.

Since I have been using M1 0W40 in every car and truck I won that is not diesel it makes life simple as well.

M1 15W50 is so thick I doubt you would need the grease although the grease has EP additives not precesent in 99% of motor oils!

 

[mauser284]

I would recommend against using any grease that has bentonite clay as part of it's make up.

The only time it is not prudent to lube the snot out a semi-auto is if you plan on being in a place that has a lot of fine sand and or dirt.

The "Sand Box" aka Iraq was notorious for it's baby powder like sand. You might find yourself in a situation where you might not be able to clean for some time. In a situation like that over oiling or fluid grease like LSA could be a huge problem.

On the other hand a range queen that get's cleaned regularly this is not an issue.
