I am 1st time owner of an M1A standard loaded. I havent even fired it yet. I have heard it is good to remove the factory oil before 1st use. My basic question is what type/brand of oil do you recommend for the interior working parts of the rifle, and what type of oil would you recommend for coating the exterior metal surfaces? Any help would be greatly appreciated. I have never owned such a beautiful (& expensive) firearm and I want to treat it with the utmost care. With that said, does anyone recommend using solvents as well? Thanks.
I am fairly certain ( others know better than I , I am still a newb compared to the guys on here), that grease is better for the working parts of the rifle, oil for the outside.
I use tetra gun grease on the internals and I clean the outside, ( and the inside I guess as well) with Ballistol. Some folks might not like to use ballistol but its safe on the entire rifle so that is a plus.
There are alot of different greases out there that people swear by, lubriplate etc. Tetra is a relatively new one but so far it seems to be pretty good.
As for why grease and not oil? I believe the rifle was designed back in the day with grease in mind, its a little more durable than oil too.
I use tetra grease as it stays where you need it to as apposed to oil which runs allover the place. But when i get into the smaller parts like the bolt i use 3 in1 oil to seep in to the small spaces.
As far as solvents go. I've used a variety over the years. I find that Simple Green mixed 50/50 will strip the gunk off the metal of my guns very well. Also I'm more motivated to wipe on a good coating to protect from rust afterwards. Lately I've been using Balistol more and more and haven't any complaints yet.
But certainly lube your M1A with grease!! I see no problem with any of the one's mentioned previously.
I oiled my M1A for right at 30 years because that's what I was taught in the US Army. Nope, no grease, ever, not in 4 years. 3n1 oil kept my M1A going for all that time with no issues. No, I didn't shoot 300 rounds a day. Just target practice, load development efforts and deer hunting. No issues.
Then I got my first M1 Garand and started greasing. Now I grease my M1A, too. I use marine grade bearing grease since that is more resistant to water/moisture than standard greases.
I use Mobil 1 motor oil (10W20, 10W30, etc. - depends on what I used last in one of my vehicles - I set the empty jugs up for a few days and let the left over oil drain to the bottom and then pour it into the little clear GI oiler bottles - works great) for lubing the trigger assemblies, sights, wiping the outside surfaces, etc.
