Kak Industry
The Kak Industry AR-15 Upper Completion Kit gives you all the small parts and springs needed to finish assembly of a stripped AR-15 upper receiver. If you're building an AR from a bare upper and don't want to hunt down individual components, this kit bundles the hardware that often gets overlooked—the forward assist assembly, ejection port cover, and related springs and pins—in one box. It's built with phosphate finish for solid corrosion resistance in the field.
This is ideal for AR builders who source their receivers separately and want to avoid the frustration of discovering a missing roll pin or spring mid-build. Kak Industry knows what shooters need, and they've packed the essentials here without the bloat. Whether you're putting together a hunting rifle, a range gun, or something in between, having these pieces ready means your upper goes together smoothly.
The phosphate finish is proven for durability and won't let you down in wet or harsh conditions. All the small stuff is accounted for so you can focus on the build and get to the range faster.
| Brand | Kak Industry |
| Product Type | AR-15 Upper Completion Kit |
| Finish | Phosphate |
| Contents | Forward assist assembly, ejection port cover assembly, springs, pins, and clips |
The kit includes a complete forward assist button with pawl (claw), helical spring, and roll pin. It also includes the ejection port cover with rod, spring, and C-clip. Everything you need to finish those critical assemblies on a stripped upper receiver.
This kit is designed for standard AR-15 upper receivers. If you're building a proprietary or non-standard upper, confirm compatibility before ordering.
Yes. Phosphate finish is a time-tested protective coating that resists corrosion well in field conditions. It won't protect against neglect, but it's plenty durable for hunters and shooters who maintain their gear normally.
The kit provides the components; specific installation tools and detailed instructions will depend on your upper receiver and build setup. Consult an AR-15 assembly guide or manual for your particular receiver if you're new to builds.
