Our company adheres strictly to these regulations and will not accept orders for these products from residents or for shipment to the State of California. Additionally, it is essential to adhere to all applicable laws, especially the Gun Control Act (GCA) of 1968, which requires individuals to be at least 21 years old to purchase firearms from licensed dealers. For comprehensive guidance, consider consulting with a legal expert or your local ATF representative.
