Grease on KAC SR15?

[230therapy]

I have a KAC SR15 and am currently lubing it with SLIP 2000 EWL. This product works fine.

However, I have a tub of Lucas X-TRA Heavy Duty Grease (wheel bearing grease). The label lists it as for:

High speed bearings
High temperatures
Extreme pressure
Irregular maintenance
Electrical contacts
CV Joints

Additionally, it says it's designed to:

Exceed all marine application specs
Resist slinging out of fast moving parts
Resist washing out of steering components on wet roads
Resist melting at high temperatures (560 degrees F)
Resist squeezing out under heavy loads
Maintain a constant film of protection under irregular maintenance schedules

Is this something I could use on an SR-15? I'm looking for something that won't go away as quickly as oil. I want to reduce the frequency of lubing the rifle (especially the bolt).

I highly advise you not to use grease. Slip2000 EWL should be more than adequate. Apply it to the BCG generously and be done with it.

What does grease not do in an AR-15? What are the problems with grease as lube an AR-15?

Grease is generally not needed in an AR-15, the moving parts are pretty well contained and oil migrates around. If you like cleaning moly off of everything you could put synthetic moly on the sliding parts but it's realllllyyy not necessary.

Just use ATF fluid/CLP and it will last longer than you will.

Wheel bearing grease has a much higher viscosity than oil and places more drag on the moving parts

I put a little Lucas red n tacky #2 on my bolt once before firing a few hundred rounds. It didn't burn off and it stayed in place. I won't be doing it again, it doesn't cause any problems, its just not necessary.

I haven't used Slip but I have been using mobile 1 15w-50 and it doesn't burn off and it stays in place very well. The only cleaning I ever do is a quick wipe-down of the bcg. Grease just makes too much of a mess, especially on the outer surfaces of the bcg and in the upper receiver.

Is there any particular reason not to use grease? I use keep a bottle of Slip2000 or CLP handy for on the spot lubrication but I see no reason to use oil when at home performing periodic maintenance. I store my rifles muzzle up in the safe and the oil simply drips into the buffer tube and evaporates.

Grease stays on until the next outing. Specifically, I use lubriplate which has also worked well with my M1A and handguns.

For medium to long term storage I would not lube but just a wipe down with an oily rag. If you're going to the range it takes 30 seconds at most to lube the gun.



I generally keep a CLP'd rag for wipe downs, and lube out of the bottle with SLIP EWL. CLP has better corrosion resistance from what I've seen while EWL is a superior lube for firing.

I use CLP and TW25B and so far no problems. I am thinking about trying the SLIP brand in the future.

I like TW25B because it works well, non-toxic and smells great
Just use it in high wear areas.
Since LAV calls it "desert jizz" I've chosen NOT to taste it

I used Slide Glide Light on my MK12 just for storage.

Went to the range today, a bit chilly ~40 degrees. Not too bad though. Went to load the rifle and realized the buffer got stuck to the rear in the RE. Not all the way to the rear about 2 inches from going fully home. Couldn't figure it out. I have to give it a hit on the butt and it went home.

I figured to give it another try and it happened again. I realized that it was cold enough for the grease to be gumming up the insides. The BCG was also lagging in the receiver. I didn't use a hell of a lot. Just enough to coat everything.

Needless to say, the grease will not be used again. Even for storage. I just switched over to Slip 2000 EWL. So far I'm happy with it.

Ask one of our members who apparently was using grease which somehow ended up getting in the gas tube and hardening.

I just don't see the need to reinvent the wheel when the wheel works.

Good info and food for thought!
