Greasing bolt roller

I have a M1A NM and I really don't want to take the action out of the stock. Is there any easy way to grease the roller on the bolt without field stripping the rifle?

Dunno on that one. Maybe a hypodermic style greaser? I would think that once the grease is inside the roller it would stay for awhile.

If you pull the op rod back you can get an acid brush full of grease in there. Truly greasing the roller would require removal of the bolt from the action. I have been doing it with the brush and remove it from the action each year.

What about those bolt roller greasing tools? I haven't bought one yet, but I thought they worked by just filling them full of grease and pressing them hard onto the roller, letting hydraulic pressure push the grease in. No?

You have to take the action out of the stock to use one of the bolt roller greasing tools. I have one and it's a handy gadget to have for your M14 since it make greasing the roller quick and painless.

Post you have to take it out to grease properly--

you have to take her apart to clean and lube properly. i made my bolt roller tool from necking down a 44 magnum shell case a little at the time until it was the proper size and it works like a charm.

As stated, to properly grease the roller, it needs to be disassembled from the action. It should be done the same way as a wheel bearing in a vehicle was in the old days. Now they are sealed units and cv axles, (lunacy)...Anyway, to grease a bearing properly, you put grease in the palm of one hand, a gob of it, then run middle finger and ring finger in through the center of the bearing race, with the large diameter end toward your grease filled palm, then rake and push hard into the gob of grease, rotate and repeat until it comes out the top of it, hydraulically forcing it in. Same for the bolt roller, it needs to be forced in from the bolt side, till it comes out the op rod side. The only way to grease it properly is when the internal section is full. Several rotations of the roller while doing this helps. I use my knife blade or a toothpick, and laboriously flick and push it in from the inside out, till it shows on the top side. I am now working on a new tool to accomplish this easily....but it's not easy. The problem is the narrow gap you have to work with between the bolt body and the bottom of the roller, but I almost have it now. I will post about it when completed. The curvature of the existing bolt roller greasing tools and the empty shell casings, are wrong, but at this time, the best alternative,....not for long though.

Take it out of the stock.

While it's not recommended to remove the rifle from it's stock often, it certainly won't hurt once in a while. Just be careful. Most competition shooters remove the rifle from the stock at least two or three times during the shooting season. This allows for proper cleaning and lubrication. Most of the time it isn't necessary to clean anything other than the barrel and gas system, but the innards must be taken care of from time to time. When cleaning the barrel, it's OK to remove the trigger group and clean any part you can reach with your fingers and a rag or brush. Regrease and reassemble. It may take a few rounds to get the rifle settled down and shoot it's best after taking it out of the stock.

Next time I need to order anything from a parts dealer, I'll throw in a bolt roller grease tool, and add it to the collection of tools I'm slowly accumulating for M1s and M14s.

FWIW, I have a bolt roller grease tool and have found the palm of my hand to be easier to use and quicker to clean up.

I use a .45 case that I filled 1/2 way with epoxy let it harden and then just fill the other 1/2 with grease and push it on

I put a dab in my hand, mash the roller in it, rotate and repeat until it comes out the back side. Low tech and effective, leftover grease on the oprod etc...

I got her out of the stock, quite tight, and greased up the roller, and all the points mentioned for proper lubrication for the M1A. I pecked the action out with a wooden dowel per Springfield Armory instructions. Packed the roller like a wheel bearing, pressing grease until it came out the other side. Good to go! Thanks friends for the info.

The operating rod was stubborn, but went to "stickies" and followed Sustine mus's instructions. Thank you Sustinemus!

Soon as I get the chance, she will be going to the range for a zeroing-in and a workout. Man I love this rifle.

Re:

The roller greaser is the way to go, or some shell casing the right size. But you dont want to take it apart, maybe a cajun injector with some grease in it. Make it a mini grease gun.

Cheers
