Pistol Deep Cleaning!

This is what I do for deep cleaning my pistols. I don’t want to get into the endless debate over how and when you should clean, that’s up to you. I am only showing what I do.

This is a shot of my setup before initial take down.

I use my Harbor Freight ultra sonic cleaner with a 30:1 ratio of distilled water:Simple Green set on heat for 16 minutes. 8 minutes flip / adjust parts another 8 minutes. Small parts go into a jar or solution filled zip lock bag.

Gun Cleaning Simple Green HF Ultra Sonic

Then I blow everything off:

Then I drop the parts in my Bald Eagle ultra sonic cleaner with a 20:1 ratio of Distilled water:Ballistol set on 122 degrees for 20 minutes. 10 minutes flip / adjust parts another 10 minutes. I put the small parts in a jar with the same solution.

I blow and wipe everything off then lay the parts out back on the work bench.

Then I put it back together and function test. Ready for the range.

AK-74 Vise Blocks

I designed the AK74 vise block because I did not see many out there. Plenty for the AK-47, not this smaller brother.

I know it fits my Riley Defense. I made the tolerances “loose” enough that it will fit other manufactures as well, but tight enough to hold your AK in place.

Foredom Yoke

I wanted to make a Yoke assembly for my Foredom motor, something like this one.

I had this big bearing from a previous project. This led me to create 2 versions:

Big Bearing:

And a standard 608 Skate Board Bearing version:

The insert works for both:

Looks and works pretty good! I have been using the large bearing version for around 6 months with no issue. I am not a heavy Foredom user, it is a tool in my tool box.

BCG to Buffer Space Gauge aka 2 Quarter Tool

I think School of the American Rifle started the 2 quarter spacing from the AR15 gas key and the receiver extension. I can not find an exact minimum spacing in the Army TM 9-1005-249-23&P Nov 2008. It makes too much sense for it not to be in there. If someone knows let me know and I will put it in the references.

I never have quarters in my pocket when I am working and if I do I will only have 2, what if I need it to fix a spacing issue? So I came up with this little gem.

It measures 2 quarters / 3.5mm thick and has a few stops to help hold it in place while you are cramming your BCG back trying to get the gauge.

AR15 Buffer Spring Measurement Jig

REF: Army TM 9-1005-319-23&P Nov 2008, Page 0021-10:

Check free length of action spring. RIFLE ONLY: The free length must be between 11 3/4 in. (29.85cm) minimum and 13 1/2 in. (34.29 cm) maximum. CARBINE ONLY: The free length must be between 10 1/16 in. (25.56 cm) minimum and 11 1/4 in. (28.58 cm) maximum. If measurements are notaccurate, replace. Do not attempt to adjust the length by stretching the action spring.

Your manufacture might be different, in making the jig I used the above.

If you have a 3D printer it is a cheap print. This is too long for a standard print bed, I used my Ender Extended 400×400 print surface for this one.

You can download the STL on Thiniverse

To help check the length of your buffer spring I created 2 versions of the AR15 Buffer Spring Measurement Jig; Rifle and Carbine length. The Center is minimum length and the other is maximum length. Your printer might be different so double check measurements after printing.

AR15 Gas Block Tool

A tool to help hold your gas block while you are trying to drive the gas tube pin in or out. It is plastic, if you beat on too hard or too many times it will break. Not to fear! it is a cheap and relatively fast print.

As an extra bonus, I created a extension tube holder!

Glock Trigger Jig

A quick jig to hold your Glock Trigger for maintenance and / or training. Kinda cool to pull the trigger and see how things work.

Also good if you are doing something like the 25¢ trigger job. See how everything is running before you drop it back in.

I include the white trigger pin file ‘Glock Trigger Jig Pin.stl’. I just use one of the extra pins that come with the back straps for the trigger housing pin. I print it with supports, round part on the bed.

The Glock Ring

This is NOT to check the diameter of your barrel or anything else! Just to check if there is a bulge in your barrel.

Glocks method of checking the barrel is to remove the slide and push it the barrel hole and make sure it does not have a bulge. I wanted something I could use on barrels that are not installed without having to remove a slide.

This example is for 9mm Barrels. I measured several 9mm barrels and slides for Glocks and came up with 0.580 inch for the inner diameter. Because printers vary check before you use.

Just slide it over your barrel and check for a bulge. PLA is softer than the barrel so there should be no marring.

Present Arms Sleeve

A sleeve to help hold your castle nut wrench firmly in place while cranking it down on your Present Arms Gunners Mount.

I can not claim this idea as my own, I was watching this video from School of the American Rifle and though “What a great idea”. I did not have any 1 ¼ inch PVC laying around, but I do have a 3D printer and PLA. This is what I came up with for the below wrenches.

AR Magazine Release Tool

I wanted a tool to help get the magazine catch pushed out of my M16/AR-15 without scratching or marring the metal. To compresses the spring and make removal of the magazine catch easier.

Looking around I saw AR Magazine Catch tools similar to mine on various web sites for around $10 without shipping. I am frugal and own a 3D printer, I decided to make one.

I know you can use many other things to push it out, such as, but not limited to, pencil, punch, your kids finger….If you have a 3D printer it is a quick and cheap print.
