Stripped Upper Receivers
WHAT IS A STRIPPED UPPER RECEIVER?
A stripped upper receiver is the foundation of a firearm. It houses the barrel, bolt carrier group, and charging handle to the lower receiver. It is the first thing you will need after you complete your 80% lower receiver.
An armorer’s wrench, headspace gauge, vice and other simple garage tools are all you need to assist with building an upper receiver.
Why Choose A Stripped Upper?
The upper receiver houses the most commonly customized components in the AR-15. Whether it's a precision barrel, or a new charging handle, it often makes more sense to build from the ground up, rather than to replace parts later on. Save some money and do it right the first time!
This is why stripped uppers are so popular in the 80% community. It allows a builder to get to know their rifle intimately and to modify an upper to their exact specifications with the quality parts they want. Let's face it, nobody wants to have the same thing as everyone else, and it's always more satisfying to build it yourself.
