I did not like the way the trigger housing moved when manipulating the trigger. So I added a brace. I printed it with tree supports that need to be cleaned up before using it.

The glock 48 front rail is smaller than standard rails making it much harder to find anything that fits it. To help remedy this I made two slide over versions:
Picatinny:
And a Mantis X mount:
I would not use it for EDC / real world use. I made it to mount my Mantis trainer and various lights to see if I would like them on this weapon.

I started working on a holder for the AR15 Bolt Carrier Group (BCG) Pins. The idea came from School of the American Rifle. I wanted to be able to remove the pins if needed. I also did not want to paint my pins for GO / Warn / NO-GO. Here is what I came up with.
Got everything printed up in the right colors and numbers. You can switch it up how ever you like:
Everything printed up in the right colors
Then I put it all together. I had to cleanup everything with sandpaper, file and an Exacto knife. With a little help from a small nylon hammer. I got everything in place. Even tried a little infill using model paint.

Added all the pins in:

So far it is working out pretty good. It is another tool in the toolbox when troubleshooting AR15 Bolt Carrier Groups (BCG) The pin sizes are born out of the data I pulled from my research HERE.

A simple and effective holder to check the spacing from the AR15 gas key and the receiver extension. Use of theBCG to Buffer Space Gauge aka 2 Quarter Tool is documented on many popular blogs and YouTube channels.
I can not find an exact minimum spacing in the Army TM 9-1005-249-23&P Nov 2008. If someone finds it let me know and I will put it in the references.
I like to make things 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 Bolt Carrier Group back trying to get the gauge.

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.

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!

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.
A quick jig to hold your Glock Trigger without trigger
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.

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.

My Present Arms Gunners Mount Kit is awesome. The one thing I wanted different was the Receiver Alignment Block. It does not seem to fit right on non-mil spec buffer tubes I work on. How can they know all the sizes?
You can see the gap here, it will not seat all the way.

And that is because the buffer tube rail is too wide.
