The purpose is an enjoyable hobby. I'm not a competition shooter, I am new to the rifle world, and I thought it might be helpful/useful for some who were in the same boat I was in a few months ago to see what options/accessories are available and what I used on my particular gun. Sure, I spent a lot and maybe for no good reason other than sheer enjoyment and learning how to basically rebuild my rifle from the ground up.
If the proverbial SHTF, then it should still provide good use for defense, hunting, bartering, etc without a "significant" loss in value
