Ruger MKII Cleaning

The Ruger MKII "beginner gun" had started getting a sticky sear return, so I disassembled it for cleaning tonight. While I will totally detail strip the gun if necessary, this is as far as I need to strip it for a thorough cleaning.

A blast of aerosol brake cleaner into the lock work, work the mechanism to allow it to seep in, and wipe away. Then a bit of powdered graphite and a touch of grease on the hammer notch and the pistol was ready for reassembly. The blast shield was working well. It had an eigth of an inch thick layer of black soot caked on it. There was no gritty trigger. Underneath the blast shield, the trigger was as clean as a whistle. However, around the hammer and sear, so much crud was built up that the trigger reset was sometimes delayed. My usual Ruger MKII post shooting clean-up consists of a poke around the chamber with a bronze brush and patch, a bore snake and a wipe down. It takes many, many rounds to build up the residue of shooting in the rear of a MKII.

Far too many people believe they must field strip these pistols every time they shoot them. I know several shooters who have continued to shoot MKIIs with no cleaning what so ever. The MKII design allows for a minimum to no maintenance. It is truly one of the most durable and simple pistols ever built.

my "Fishing gun" reg trademark Xaviercorp,Inc
is much too "new" to allow me to let it get to the cruntchy scritchey triggger cutting trenches into gook stage..but I am trying to get it there...LOL

I got a second hand point sight and a AIMTECH APM-5 replacement grip scope mount that sets it up over the barrel with sights..semi usable,well see how she runs set up like that
google sucks,took me a half hour to remember who makes them..
take off the RIGHT grip,add this booger...instant scoped pistol,without drilling and tapping two MORE holes in your prized firearms.

also sold here at midway...

"My usual Ruger MKII post shooting clean-up consists of a poke around the chamber with a bronze brush and patch, a bore snake and a wipe down."

I used to counsel most customers (of the "twice a month shooter" variety) to do just that: Boresnake, toothbrush, maybe some Gunscrubber or suchlike, and then bring it in once per annum for a detail cleaning.

I've heard that frequent cleaning of .22's wears out the rifling faster than shooting them so I don't clean a Mk II until it starts to malfunction.

I can imagine this is especially true for Marlin's micro-groove barrels.

Do you think there's any truth to this school of thought?

Is it better to buy a used MK II or a newer III?

As a person who actually went to college to learn to be a gunsmith after he went to a college about economics, I shoot mine past the point of silly and they still function. Then I shoot solvent in the netherworlds and let in soak in a bit. Blast it out with 120psi of compressed air. Lube it more or less as you do yours. Barrel gets whatever attention it needs. Slap it back together and go put thousands of more rounds through it.

A customer's gun get's taken to pieces and done properly. I shortcut the cleaning on mine because I've never had any problems doing so but then I'm not paying myself either, am I?

Never could understand people saying Ruger .22 pistols were troublesome to maintain.

I even built one once with an under 1 lb target trigger and you could thump it on the bench as hard as you wanted and it wouldn't slip the sear. I made it 3.5lbs before I traded it.

Probably the only fully parkerized instead of blue or stainless Mk II target in existence with a match trigger. I doubt R**** has even done anything more than boresnake it since I was talked out of it by a Leupold binocular for gun trade and is still nailing rabbits and feral animals with it in a reliable fashion...

H/T to Ruger. He did some questionable things in gun politics at times but he knew how to design a .22LR pistol.

I just the other day decided to clean my two year old Mark III. It wasn't malfunctioning at all. There was plenty of glunk built up though. I've long been a proponent of "less cleaning is better than more cleaning". Unless my hunting rifles get wet, I just leave the barrels dirty until I notice accuracy falling off. 22 LR barrels rarely need any cleaning.

I've notice mine, after about 250 rounds the ejector starts to fail to eject. A good cleaning generally restores function for another 250 rounds or so. I'm thinking I may need to order a new ejector from Volquartsen.

upon closer inspection, the ejector hook is missing, but I can't figure out how to disassemble the ejector assembly out of the bolt to replace it. Apparently the ejection was due to recoil alone.

I just picked up a very nice Mark II last weekend for my daughter (19) I gave her a Walther PPK in .380 but she is all over the paper. I thought we would go back to basics with a nice .22
