Compatibility and Assembly Guidance

Each lower requires specific parts for completion. For the AR-10, we recommend using our LR-308/AR-10 Lower Parts Kit for optimal fit and function. To assemble, you’ll need lower parts kits, buffer tube kits, and upper assemblies tailored to each platform. Our detailed guides provide step-by-step instructions, making the process accessible even for beginners.
