We all know the factory Glock sights are notoriously poor, so let me replace them! I take a lot of care to make sure the sights on your pistol are installed and aligned correctly. I have a very nice sight pusher tool that drifts the sights on and off without the need of a punch or hammer. Using such a tool protects tritium vials from breaking, prevents marring of the slide, and the sights.

I just picked up the Recoil Management System, Versatility Kit from the great folks at SpringCO for my Glock 19 Gen 5. I wanted to show what I did to get it installed. It was pretty straight forward and easy to do.
Here are the parts that came in the package.
SpringCO Glock Recoil Management System Whats Included
I am going to install the Green 13# spring. As this is a non-captured setup I will be trying the 15 and 17 pound springs in the near future and keeping the one I like best and works best for my situation.

Remove the existing recoil spring

Make sure the Guide Rod Forward Bushing goes in with the small section forward as show in the picture:

Here are a couple more shots of what it should look like:

Slide the spring you want to use on the guide rod:

Place the spring in the Guide Rod Forward Bushing and carefully push in place. The guide rod will fit into the hole in the bushing.

After everything is lined up everything will fit like the original.

There are several videos that explain what is going on with the system when it is installed. I wanted to share my experience getting it installed.

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.

Dimpling your barrel to help secure your gas block is key to ensuring the gas system of your AR will continue to function correctly. A loose gas block can cause havoc to the cycling of your AR. I dimple at least once directly under the gas port. I can dimple twice, but realize that different manufactures have different spacing for the second screw. If you want or need to change your existing gas block you have to use a gas block with the same set screw spacing. Not a huge issue for some, but if the new gas block you want has a different spacing you would need to get another barrel to accommodate the different spacing.
