Introduction: Ruger 10/22 DIY Auto Bolt Release
This is how to remove, modify, and reinstall the stock bolt release on your Ruger 10/22 so you will no longer need to use the bolt release tab on the bottom of your rifle to release the bolt.
I'm not in any way the first person to do this but I thought I would put it here to save you the time of finding and reading other peoples forum posts etc.
If you get carried away don't worry you can get a new stock part from Ruger for about $3 or an already modified part from several companies (just Google ruger 10/22 auto bolt release) for about $10.
If you have purchased this part instead of modifying your own, this will serve as installation instructions
As always before we get started with any firearms project do your safety check (both visually and physically inspect that your weapon is unloaded) and proceed at your own risk.
- Mallet (may not be necessary but good to have)
- Spacer block for removing pins, I'm using a role of blue tape. (recommended but optional)
- Pin punch (you should already have this for cleaning)
- Small Files (A sightly rounded file and full round file (you can probably use just the dremel tool, but these will help shape and smooth the areas we grind away)
- Flat head screw driver.
- Dremel Tool with a small grinding or engraving cutter (you can use just the files if need be it will just take a lot longer)
Recently re-shot this tutorial as a video if you prefer that to the slide show.
Step 1: Disassembly
- Remove the stock by, unscrewing the barrel band, and the take down screw on the bottom of the stock.
- Slip out the assembly seen below in image one
- Push out the two lower pins with your pin punch and your spacer, if your have trouble pushing it out use a light tap from your mallet. Be careful not to lose the top pin (bolt stop) as it has a tenancy to slip out on its own.
- Slide out he trigger assembly as seen in image two
- Remove the two highlighted pins in image two and leave the rest. When removing the top pin, slide out and set aside the extractor seen in image three paying attention to the orientation.
- At this point your should be able to wiggle the bolt release free as seen in image four. If you have trouble follow the instructions in image five.
- You should now have the bolt release free as seen in image 6
Step 2: Modification
- Use your gun cleaner to remove any oil on the part, and dry it off so it will be easier to handle.
- We will be grinding/filing off the indicated areas of image one.
- Image two is what we are trying to achieve.
- I don't have a Tri-Pod for my camera so I couldn't take video of this part, but take you Dremel and remove the bulk of the material, and do the final cleaning up with the small files.
- On the larger arch don't just grind it off flat. It needs to have a slight arch as indicated by image two. The exact shape of the arch doesn't really matter too much but make sure it's a smooth transition from the two corners at the top left and bottom of the hole in image two, and try to remove as little material as you can to achieve the pictured result.
- Take your files and try to get the inside of the hole as smooth and polished as you can, and clean up any burrs and or sharp edges you have created during the process.
- The part is done once it looks like image two.
Step 3: Reassembly
- Add a light coating of gun oil to the part
- Rotate the spring all the way back as shown in image one.
- Reinsert the modified bolt release
- If you removed the magazine release put it back the same way you took it out
- Align the bottom hole as pictured in image two. (you may have to move the mag release a bit to get it aligned) and re-insert the bottom pin;
- Align the top pin holes as seen in image three but do not re insert the pin yet
- Rotate the spring forward again seat the spring arm in the small slot of the bolt release as shown in image four.
- Partially re-insert the top pin, and hook the top spring arm under it as seen in image five
- Slip the Extractor back on the pin and push the pin the rest of the way through. it should now look like image six, and you are home free... now just reassemble the gun as you normally would.
- Slip the trigger assembly back into the bolt housing, and reinsert the pins and bolt stop pin.
- Slip the whole assembly back into your stock and re-tighten the take down screw and barrel band screw.
- You are now finished.
Step 4: Final Result
Now lets check our work.
You are all done, and have saved yourself a few bucks in the process and maybe learned a thing or two along the way... good luck, have fun, and shoot safe.
