AR15 Rifle Greese Points
Contributed by Ken Russo


First you have to disassemble the rifle. 

The AR15 bolt has three gas rings, they need a drop of oil and the gaps between the rings cannot line up otherwise you'll have blow by and the rifle will not cycle properly. If you ever have trouble ejecting and feeding rounds, check this area first. Keeping an eye on this area is simple preventive maintenance.

The upper receiver will have 4 places where the bolt carrier rides inside. It'll create 4 shiny tracks where you'll have to lube the receiver to prevent the steel bolt carrier from digging into the rifle's aluminum body. Here's where the curved grease applicator comes in handy.

I have been to Advanced AR15 carbine patrol rifle schools as a Law Enforcement Rifle Instructor and this is often neglected. Oil works well, but the heat generated by firing will often cook off the oil and also splatter hot oil from the ejection port. Grease if used sparingly will not splatter and will not cook off during normal to hard use of this weapon system. Remember grease also attracts dirt, so go easy. A properly lubed AR15 is just about jam free, and most of the jamming problems in rifles I have seen are (lack of) lubrication problems.

Also lightly lube the bolt's 4 races and when the bolt is inserted back into the upper receiver, the excess can be wiped away with a cloth or a cotton cleaning patch.

Next the charging handle...

There are 4 places that need a dab of grease.

The upper portion to the rear of the handle, the front near the little lobe, and on the ears on the sides of the handle. Not much is needed, but the charging handle rides in a race and needs to be lubricated. Dry handles hang up especially when they get hot and the handle is also the Achilles heel of the AR15. It's the weakest part of the rifle and needs to be straight and free from bends.

Lube the charging handle and use only a little dab of grease on the 4 areas.

The upper receiver, now...

the AR15 needs a dab of grease where the charging handle locks onto the upper receiver. Remember the upper and lower receivers are aluminum 99% of the time and the charging handle latches are steel. Just a drop of grease will prevent premature wear.

Lubed charging handle and the grease syringe from Sinclair International, I like the curved applicator..makes getting into the upper receiver easy.

Once this method is used to lubricate your AR15, I am sure you will notice a difference in smoothness of operation and increased reliability.

Shoot safely,

Ken
