Description
Building an AR-15 upper from a stripped receiver means sourcing a handful of small components that are easy to overlook until you need them. Wilson Combat’s Upper Receiver Parts Kit addresses that problem directly, bundling every internal part required to bring a mil-spec forged upper to a functional state. Rather than hunting down individual pieces from multiple vendors, a builder gets a complete set in one order.
The kit centers on a mil-spec forged charging handle assembly, which provides the standard geometry and surface area that most AR-15 shooters are already familiar with and that works with a broad range of aftermarket latch upgrades if preferred down the road. The forward assist assembly and its corresponding roll pin and spring allow the bolt to be manually seated when a round fails to go fully into battery — a function that matters most under adverse conditions when chamber fouling or debris slows the bolt carrier. The ejection port cover, its roll pin, retaining clip, and spring round out the package, keeping the chamber protected from debris when the rifle is not in use and snapping open automatically when the action cycles.
All told, this kit covers the components that builders most commonly find themselves short of mid-assembly. It is a straightforward, practical solution for anyone completing a mil-spec forged upper build and wanting to source these parts from a single, known manufacturer rather than piecing them together from assorted bins.
