Spring Included: The XTS BR comes with a spring that works in conjunction with the buffer retainer. This spring provides the necessary tension to keep the retainer engaged with the buffer.
Durable Construction: The XTS BR is constructed from durable materials, often steel or similar alloys, ensuring strength and resilience to withstand the forces generated during firing.
Drop-In Replacement: The XTS BR is designed as a drop-in replacement for the standard buffer retainer found in most mil-spec AR-15 and AR-10 rifles. This makes it easy to install without requiring any modification to the firearm.
