I believe the Ruger is a piston action and it doesn’t need as much oil as the typical gas action AR style rifle. I’ve still always kept an AR weapon with a wet bolt.
I suggest as light a weight oil as possible.
I like to use Marvel Mystery Oil as a gun lubricant. It’s very light, very slick and easy to remove when needed soiled
Catch-22. The oil could attract grit.
In the army, we would clean the M16 and leave it bone dry when stored...and the next time they fired, they would again be bone dry. I don’t think that was the best thing to do...but it leads me to believe that a light coat of oil would likely be fine.
A light sheen, The AR is a piston, pistons need some oil the most common problems is to little oil and to much oil.
Just slather it with Diesel oil.
Should be fine.../S
I dry mine, then wipe with an oiled patch/rag before storage. Just enough for a sheen. A couple of drops on the bolt (and piston) prior to firing at the range. Never had a problem.
Now also consider I live in Colorado so I have a much drier climate than most.
They will run dirty but not dry.
However much oil the guy with the AR-15 says is too much.
Enough to protect it from full immersion in the fishing hole it will eventually end up in the bottom of.
I like mixing the gun oil with a lot of kerosene.
I can then slather things up as much as I want and when the kerosene evaporates, the oil left is very thin.
Just slap some bacon on it and fire away. The melting bacon will lubricate the action and the barrel heat will cook the bacon. A very tasty win-win solution.
A direct impingement AR will run better when well lubricated. The disadvantage is that it will tend to attract grit and dust if you are operating in that type of environment.
If you keep the gun clean, shooting in low wind or low dust, a light oiling (whats left over from cleaning with clp) and an extra drop or two wiped on the bcg will do you right. If you get in a dirty environment the gun will keep firing no matter how dirty as long as you keep it wet. But... keeping it wet attracts more dirt so you will be in for a serious cleaning session. YMMV but this has been my experience shooting in desert environment.
I remember reading that back in 1968, the Vietnam war saw so bad on M-16s that a company named DRI-SLIDE was sending lots of a dry lube to the soldiers there.
Where I live now, NW Arkansas, I have to keep all guns and iron items covered with petroleum Jelly, and a small amount of oil or WD-40 on the interior.
Go the army way lightly. Oi trigger group wiring off excess. Oiled pistons are an anathma due to carborization. You absolutely do not oil M1, M1 carbine, M14 gas pistons due to the fact. Excess oil is always problem be it desert or artic. Excess oil is aso easy to get into the chamber causing excess pressure and accellerated extraction.
Get some Ballistol (Ballistic Oil) and use it. Ballistol leaves a residue that protects metal and makes it very slick. Plus the smell makes for entertaining times with your spouse and others in the vicinity.
Uhm, well...the first thing that comes to mind is THE FRICKIN' GAS PISTON! ;o)
The wetter the better..... Yeah....
The piston gun will not blow oil out of the upper receiver, so not so much. I use Tetra Gun Grease, which is a white, teflon-based grease. I only apply it to the four contact points on my bolt carrier and around the bolt itself. When I run it HOT, I use BreakFree CLP to keep it somewhat wet.
