SBR Ready Configuration

This kit ships without a brace or stock. It is intended for customers who are selecting their own final stock or brace setup based on their specific build plans. The right choice depends on individual setup needs, so the brace or stock is left to the buyer rather than included here. This keeps the kit flexible for builders finishing their configuration according to their own compliant setup.

Follow safe handling and manufacturer instructions. Ensure compliance with all applicable federal, state, and local laws. Lower receiver not included. Ships without a brace. Do not attach a stock unless compliant with applicable laws.
