AR 15 Build or Buy?????

This is a VERY COMMON QUESTION!!!!

          There is no simple answer for this question.  It  ALL boils down to what You want to do...

Price wise you would probably break even.

The comparison:

Building:

100% customized to your liking as you go
You control the speed of the build
A lot of resources to help
A lot of parts to choose from


Buying:

Instant gratification (after 10 day waiting period of course)
Money up front
Many models to choose from


So, it is TOTALLY up to you which path you take.  Your need for the rifle may determine your AR path.
