A popular saying for the past few years has been "go big or go home". Now, that may ring true if you're competing in the Olympics but when you're new to building AR-15's, maybe not so much. Okay, if you happen to be a professional armorer or have numerous builds to your credit, you likely know exactly which parts work best. However, going in pretty much blind, just how can you tell? Some parts simply don't play well with others. That can be an expensive lesson to learn. For those who require high quality parts on their AR-15 down to the smallest pins and springs, the Spike's Tactical Lower Parts Kit is the way to go!
