Re: I F###ING HATE RUGER!!!
I presently own and shoot these 3 Ruger Mark II and Mark III .22 pistols. I've fired thousands of rounds through them. I do not understand why people feel the need to disassemble these guns when it is totally unnecessary. If you want to get your Ruger Mark Pistol spotless, there is a much faster, easier way to do it.
Go to Home Depot or Lowe's and purchase a gallon can of Kerosene or WD-40. (WD-40 smells better and is easier to find). It runs around $12 to $14 a gallon, and will be the best money you ever spent.
Pour about a quart into a clean 2 pound steel coffee can. Pick up several of those fake Camel hair paint brushes in the paint dept. while you are there. Cut the bristles down to about an inch long with a sharp pair of scissors. (This helps the bristles stay stiffer). Remove the magazine and give the gun a good wet cleaning. Brush the WD-40 or Kerosene into everything. You won't hurt a thing. It will not attack plastic, or the finish on your grips. Flood it liberally into the action, down the magazine well, and especially in and around the bolt face. You will see the black gunk ooze out, and the solvent turn black as you proceed.
Keep flooding everything until the drippings come out clear. Then give the entire pistol a good blowing out with compressed air. If you don't have an air compressor, or else live in an apartment, you can buy a small portable unit from Harbor Freight very reasonably. These are perfect for cleaning guns.
After you blow everything completely dry your pistol will be cleaner than the day you bought it. I then re lubricate the weapon thoroughly, and wipe it down with an oily rag. There is zero need to disassemble these guns unless they break. I do much the same with all of my bolts from my bolt action rifles. I have never taken a bolt apart in 40+ years of shooting, simply because there is no need to if you clean by the method I've outlined above. It gives a very good result, and makes life a lot easier in the process. Bill T.
