I pulled out my old Ruger .22 that I haven't shot in decades mostly because I have many other .22s to shoot and I forgot how to out it back together. (I remember trying each time to remember the "trick" to reasemble the last piece). I do love it though.

Anyway I can't figure out if it is a Mark I or "Standard". Bought it in 1976 and is marked "Made in the 200th year of American Liberty". (Hope that holds true in the future). There is no "Mark I" but simply "Ruger 22 cal. Long Rifle Automatic Pistol".

Is it a Standard or Mark I?

Does it have adjustable sights? Mk I. Standard doesn't have target sights.

However, the mechanism still follows the various Marks. So, some people refer to MK II target or standard versions.

Most feel the present MK III was a mistake, the MK II being the full evolution of the design, with no "improvements" needed.

Look at the back of the receiver, right in front of the "ears" that stick out on the bolt. If it is recessed, it is a MkI, if it doesn't, it's a Standard.

Some standards also had target sights. They came in 4 3/4" and 6" barrels, and some had bull barrels.

The slide stop on the Standards would not hold the barrel open, but would on the MkI

Texas Star is spot on.

I have a 1976 Ruger Standard. It's a six-inch barrel, fixed sights and has the same bicentennial inscription.

I wish I had a quarter for every round I've fired from that pistol!

you have a 1976 made 'standard auto' ( fixed sights) these are NOT marked "Mark I".......
as for putting it back together make sure the bolt goes in, pull the trigger to lower the hammer, it MUST be forward... push the mainspring assembly ,up and into the receiver from the bottom, make sure the "pin" goes all the way up and through the top hole, now you can tilt the gun on an angle upwards, and look up ,inside , behind the hammer, you will see the strut, , and it should be 'free" and dangling downward, and as you swing closed the mainspring assembly ,back into the frame, this 'strut' MUST go into the top of the mainspring assembly.......and it will then Lock in place, the lever will close and you will be able to "cock and dry fire" the gun...if this doesn 't happen , you "missed" getting the 'strut' into the proper location...this is the main problem/issue with re-assembly of any of the Ruger 22 semi autos, standard or target ( MKI I & II....)
good luck, if ANY problem get a hold of me and I can and will talk you through it....been doing this since the 1950's.........

Charlie-

I think I should politely tell you that I think you need to go study Rugers more before posting.


Or, maybe I'm wrong. But I think you're confusing Mk I and MK II guns, and that no Standard model ever had a bull barrel or target sights. If you have one, please post photos.

The scalloped area just ahead of the bolt handle/knobs was incorporated in all MK II models, Standard and Target. The MK I Target model didn't have that recessed area. And I believe that the bolt release didn't appear until the MK II.

Just to refresh my memory, I got out one of Larry Koller's old gun books and checked the photo of a MK I Target. No scallops, no bolt release.

Gents,

On the first model Standard Auto, and the Mark I Target versions of it, the bolt can be locked open by putting the safety on while it is open.

Hope this helps!

Looks like a Standard guys based on all the comments. 6" barrel, fixed sights, bolt handle sticks out and not recessed.

Thanks all. Will bring this one out of retirement to play.

Ok, I'm getting confused in my old age. They didn't call the "first" one a MkI back in the day. Yes, the "MkII" has the beveles infront of the bolt ears.

I had an early one...i.e. 1961. I purchased it new at the time for $37.50.

Back then they had the 6" and the 4 3/4" tapered barrels. They came with fixed sights. For slightly more money you could get the 6 3/4" with an adjustable sight. There were also blull barreled target models back then too.

Sorry about the confusion of MkI and MkII.

The original Ruger designation was something like RS4? They were refered to in all the literature as Standard.

Back then, when you refered to a Ruger .22, it was the semi-auto. That was all there was. This preceded the Bearcat and the Single-Six. When the revolvers came out, the auto became the "Standard".

When the first auto came out...the term "MKI" had not even been thought up. I think "MKI" came into being after Ruger changed the design to the new model.

I had one that cost about 54.00 with fixed sightsback in the early 70's I took the paper clip like it said to disassemble and I like to never got it back together even with the directions, I have never taken another one apart. Jeff

If anyone is interested, here are a couple of links to a pretty good guide to field stripping and re-assembly.
