Shipping & FFL

Because the RL556v3 80% AR15 Lower – White is not a completed firearm receiver, it can be shipped directly to your residential or business address with no FFL transfer required. No background check is needed, and no federal waiting period applies. However, please be aware that once you complete the machining of this lower receiver, it becomes a firearm in the eyes of the ATF. At that point, you are legally required to serialize it and comply with all applicable state and federal laws regarding firearm possession and transfer. We recommend that you check your local and state regulations before purchasing, as some states restrict or regulate 80% receivers. We do not ship this product to jurisdictions where it is prohibited by law.
