Glock 48 Rail Mount

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 plan on making a more secure version soon.

A bore guide with holding pin for AR-10 .308

I have been using a bore guide on my AR15s for several years. I recently purchased a .308 AR10 and set out to make one for it.

I liked @ThomasXIII threaded middle shown HERE So I made mine with the same threaded center.

I also made a hold down pin to keep everything in place.

AR-15 Bolt Carrier Group (BCG) Test Pin Tray

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:

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.

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 Custom Receiver Alignment Block

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.

Present Arms Receiver Alignment Block Original Bottom — You can see the gap here, it will not seat all the way.

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

Present Arms Receiver Alignment Block Original Top — And that is because the buffer tube rail is too wide.

So I do what I do and made one. Seats all the way down

And tightly fits the buffer tube rail

The metal rod it ¼ inch and I cut it down to just below the top.

Then topped it off with a couple of the included caps.

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.
