SpringCO Recoil Management System

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.

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:

Front:

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.

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.
