ASSEMBLY PROCEDURE

Before you begin assembly, make sure you clean and lightly oil all of the parts in the fire control group. Do not leave excess oil on the parts, as it will only serve to attract excess dirt. Replace any of the unwanted or worn parts with new or custom parts and follow the steps below.

Step 1: Install the magazine catch/release…

Insert the retaining piston and spring into the hole on the front face of the trigger housing.

  1. Impressive – The best step-by-step manual re. 10/22! One question only (I could have missed the instruction): Is there a particular direction the way cross-pins should be removed and reassembled? For example, the GLOCK cross-pins are removed from port to starboard and reassembled in the opposite direction.
    Thanks again for the outstanding instruction article!

  2. KBP,
    Good question. These cross pins are not tapered or notched, so it does not matter which way your take them out… they can come out in either direction. The direction in which I have removed them in the photos above was chosen because that was most comfortable to me. However, you may remove/install them from whichever direction you chose.

    Thanks for the feedback!

  3. EXCELLENT guide with fantastic pictures and instructions.

    Thanks very much!

  4. These instructions are great. Went together and didn’t have
    any problems. Now that I’ve done this, it is really simple.
    Thanks so much for this site. It was a real help. I have it
    bookmarked.

  5. Thanks – the instructions I had were OK, but I didn’t really understand how the magazine plunger was supposed to work until I found your version – I’m not sure I would have figured it out otherwise!

  6. Hey much thanks it was a huge help, Do you have more instructions for other guns as well?

  7. Randy,

    Glad you like the instructions. All of the instructional materials I have so far are under the “How-to Tutorials” on the upper right side of the website. More will come in the future. If you have something specific you want covered, let me know and I’ll see if I can swing it.

    Regards

  8. Thank you. I could not have installed my trigger kit without your help. Thanks again.

  9. Thanks! I was just about ready to trade off my Mini 30 due to its inability to fire Wolf/Tiger ammo. I had acquired a stronger hammer spring (from Wolff) but had NO idea how to install it! Thank you for the effort you put into this!

  10. I need more help… I got the safety button and detent spring out. Now I can’t get it back in!!! Keep launching spring across the kitchen trying.

  11. I wish I could help you with that Mack, but there are several specific reasons why I did not cover the removal of the safety.

    Just keep trying… I’m sure you will get it in there. It helps to put everything in a clear plastic bag when assembling items with springs under tension. That way, they don’t fly off into the next zip code when you slip.

    Best of luck.

  12. Thanks for the help. Love this site!

  13. Excellant step by step instructions! Would not have got it right without your help. Only thing I did differently to reassemble was cut off a 1/8 inch welding rod the exact length of the trigger/sear hole to replace the long cross pin while I assembled it and placed it in the housing. Push the long cross pin in & the short welding rod out at the approprite time & it is installed. Thanks for your time & interest to help others.

  14. An Excellent set of clear and concise instructions that I really needed to complete this task. Thank You.

  15. thanks for the information. I took mine apart and the exploded picture in the instruction were usless. thanks again

  16. Thanks for the simple instructions. Also, a #14 AWG wire cut to just shy of the length of the trigger/sear pin works great to hold the assembly together for installation. Use the pin to push the wire out when the assembly is aligned.

  17. GREAT THANKS!!!!

  18. Thank you for giving such detailed instructions. I found a lot of stuff for how to take it apart but not a lot of detail on how to put it together. The explicit step by step instructions with pictures were extremely helpful

  19. Many thanks for the notes, been many years ( maybe 20??) since I last worked with a 10/22. I just now had to “assist” my son after his detailed dis-assembly.
    Odd, seems more difficult now since the last time I did it….something about 20 years gone by?!!

  20. Took mine apart to replace a couple of pieces and could not remember how it came apart. A couple of other guides I read were terrible. Thanks for a great job in description and photos.

  21. Great guide. Working on my third 10/22.

  22. Wow! Great instructions and pictures. Now my gun is nice and clean and it was soooo easy! Thanks!!!!

  23. very very interesting. I know very little about rifles.
    Question: Once it is loaded can you just pull the trigger like a revolver?

  24. Tallie: I’m not sure what you’re asking. When you pull the trigger, it releases the hammer to strike the firing pin. The recoil energy of the cartridge causes the bolt to fly back, and the radius at the rear of the bolt pushes the hammer down to cock it again for the next shot.

  25. Thanks for your excellent instructions. It really helped me figure out installing my Volquartsen hammer without a lot of stress.

  26. How does the safety work? I took mine apart to clean and did something to the safety. Help

  27. That really is a great description of both take down and assembly. I used it to fill in for some much less complete instructions from a trigger kit manufacturer. Thanks for taking the time to put this up.

  28. Very detailed & informative. Any chance of something similar, showing what & where to check for wear?

    Reply from Admin:
    Hi GC,
    A good rule of thumb is to always inspect all contact surfaces for excess wear when you clean the gun. However, you would be hard pressed to wear out a 10/22. I have a couple of them… one is 30 years old and the other is 26-ish. Both are heavily used and have tens of thousands of rounds through them. Beyond the recoil springs, neither gun has ever had a single part wear out.
    Best Regards, B

  29. Very helpful and infinitely better than the cryptic “instructions” which accompanied some aftermarket parts. Thanks much!

    The only suggestion I would make is to use a shortened “slave” pin to hold the trigger/sear assembly together while inserting it into the housing. Insertion of the actual pin gradually displaces the slave pin & keeps everything together, since it is VERY easy for the assembly to fall apart during installation.

  30. Thank you! Clear reassembly instructions, easy to follow and worked well for me. I was especially pleased given that the whole trigger group basically fell apart after I took it out to clean the rifle; that problem was loose-fitting pins in the new plastic trigger assembly.

    I applaud you, thanks again.

  31. Excellent page!! Clear pictures, easy to follow instructions, Thank you for the time and effort you put in to this page. It made installing my trigger/sear kit a breeze and took me less than 30 minutes start to finish. Consider yourself added to my bookmarks!

  32. Great job on your thorough, easy to follow and straight forward instructions.
    You could not find a book that is more comprehensive. I have one question. Is the ejector supposed to be tight fitting and and not move in its slot in the trigger group? It makes sense that it would be stationary and may be a stupid question but I want to make sure I cover all my bases for my complete rebuild. Thanks again for the excellent guide!

    REPLY-ADMIN:

    Rich,
    Thanks for the feedback. Contrary to our greater intuitions, the ejector is not stationary. It is held in place only by a single cross-pin and gravity.
    Best Regards,
    B

  33. Great site with good information. Thanks

  34. Bought a 10/22 from my brother that he had disassembled 15 years ago as a project gun. He had the hammer spring on the wrong side, after 15 years of parts sitting in a bag that will happen. Thanks to this excellent site I saved a trip to the gunsmith, learned the workings of my rifle, and was able to put it back in service. Thank you.

  35. Thank you!

  36. Excellent views,great instructions.I have a ruger SR-22 rifle. I have not taken a part yet (will be cleaning this week fired 75-100 rounds at range this week for the first time.One question, will the SR-22 have same bolt/trigger assemblies as the 10/22?? Thanks

  37. Excellent views with great instructions!

  38. While cleaning my 10-22 after atrip to the range I noticed how cruddy the trigger assembly had become.Looking at it I thought I can do this.I got it apart alright,but after an hour of reassembly attempts through my hands up. Ruger genetally has been a good resource for tricky stuff, but their csr was no help this time. Found your website through google and thank you thank you thank you!!.Your tutorial was so clear,easy to understand and properly detailed ,after just reading it through just once I had my trigger guard reassemled in minutes.A ruly awesome tutorial!

  39. Great site. When I first took my 1022 apart to clean, no one told me all the pins would fall out and drop their respective pieces all over the floor. I didn’t even get a chance to see where most of them came from or how they fit together. When I found you site, it was a God send… Had no trouble getting everything back together again. And it all worked! Pretty good for a non techie…… Thanks again.

  40. Wish I’d read the hint about the welding rod or 14 gauge wire in the trigger/seer trick first… tried for an hour, and then ‘lost’ the spring. Have no doubt when my new spring arrives, I’ll be able to get it back together.

  41. I have an older carbine model with a metal trigger housing. The trigger broke via an improper gunlock. Ordered an aftermarket trigger but having a dickens of a time reassembling. The hammer is stuck on the sear and will only position forwards or backwards…ie not clear the sear or at least do a catch and release after the trigger pull. I have watched many videos on line and am cramping up with only two hands to do this. What suggestions do you have? I am told Ruger changed the hammer after they went plastic on the housing but I am using all original parts except for the new trigger.

  42. First of all; THANK YOU!!! I purchased a complete Volquartsen trigger group upgrade kit; hammer, sear, trigger, buffer, extractor…the full meal deal; a couple hundred bucks worth. Being a complete Virgin at attempting anything like this with a firearm, I was fully prepared to drop another $100.+ to have a local gunsmith do the work of installing it.
    I came across your tutorial completely by accident. I read through it a couple of times, looked at my SR22 a couple of times, and decided I could do this myself. Not only COULD I do it myself, I DID IT MYSELF! This tutorial is light-years ahead of anything on the Ruger site, or any other site for that matter. Without it, I guarantee that a gunsmith would have made some pocket change doing it for me. Now, after having just gotten back from the range with the gun for the first time, it was an awesome feeling to fire the first round and have everything work like it was supposed to! Thank you again!

  43. Awesome takedown guide. Thanks, mate!

  44. Excellent tutorial. There is one thing I would like to recommend though in reassembling the trigger/sear assembly. When I have pinned parts that need to fit into another assembly or frame, I often will cut a Q-Tip rod (paper or plastic, makes no difference) just long enough to hold the parts together.

    Then, when the internal assembly is inserted into the trigger housing, it doesn’t fall apart (the temporary “pin” is held in place by the housing). Once the trigger/sear assembly is positioned properly I can insert the actual metal pin, forcing the stub of Q-Tip out at the same time. I have used this “sacrificial” pin technique many times, in assembling both my 10/22 and my Colt Gold Cup Match .45 ACP pistol.

  45. Thank You. It’s 2nd to None instructions on the Trigger Housing of the 10/22 on the information Hwy period. I’m a trained hobby Gun Smith and could have Figured it all out wasting Time, but with your step by step instructions It became a breeze. Now I’m a 10/22 know it all ha ha. Much thanks. Keep it up Brother and GOD Bless You.

  46. Brothers, when changing the Hammer Spring it is best to use a Vice and a extra pair of hands – ask your Wife to help. I took a pair of large scissors and separated the two parts , took one and Modified it by cutting out a notch- actually a “U” . I use this tool to pull down the Spring while the part is in a Vice and My Wife slid out the Top Tab. Then replaced the Spring pressed it down and My Wife slide the top tab back on. Bingo! Took less that 3 minutes. I have used this Tool to replace hammer Springs and Bolt Spring in Many Rifles and Shotguns. Yes I learned the Hard Way First with springs flying off into outer space and All. The Notch or “U” should be thin
    But not too thin, just enough to get between the Spring at the Top.
