Its 11.5-inch barrel strikes a balance between compactness and ballistic efficiency, making it ideal for close-quarters engagements while maintaining effective range. The M-LOK handguard allows for versatile accessory attachment, enabling customization to suit various operational needs. Folding sights provide rapid target acquisition and can be stowed to accommodate optics. The telescoping stock offers adjustable length of pull, ensuring ergonomic comfort for shooters of different sizes or when wearing body armor. The polymer grip enhances handling and control, contributing to overall shooting accuracy. Given its classification as a short-barreled rifle (SBR), ownership of the M400 PRO SBR requires adherence to specific legal regulations. Prospective owners must register the firearm with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) and obtain the necessary tax stamp. It's essential to consult local and state laws, as regulations may vary by jurisdiction. - Handguard: M-LOK - Sights: Folding - Stock: Telescoping - Grip: Polymer Shop with KYGUNCO for the best selection, competitive pricing, and exceptional customer service.
