Primary Weapons Systems AR Build Breakdown

A lot of times I am asked about the parts that make up a rifle build, so I am revamping a series of “Build Breakdowns” that explain what parts were used to put a certain rifle together.  Each part or grouping of parts will be listed below the image and will be hyperlinked to the Rainier Arms website, or another site if not available on Rainier, where you can learn more about the parts or to make a purchase.

This build focuses on a Primary Weapons Systems Build that I recently put together.  The build started as a separate upper and lower receiver set that were mostly complete from the factory.

If you see a build that you want to know more about, please let me know.

Build Breakdown #1

Periodically I will take one of my rifle builds and break down all of the parts used to build it.  If a part is not listed, such as an end plate, it is because it is a standard AR part that does not need mentioned if there is nothing overly special about it.  I will also do my best to give you a link to where you can  find the product for sale.
