The RFB Riser is constructed from hard coat anodized 6061-T6 aluminum, providing durability and strength, just like the RFB Quad Rail. This riser is designed to work seamlessly with the RFB Quad Rail kit, allowing you to match the height of the top Picatinny rail for an extended sight radius when using iron sights. Additionally, it can be used to elevate a purchased scope, offering a more comfortable and customized shooting experience. Whether for enhancing iron sights or optimizing scope placement, the RFB Riser is a versatile and practical accessory for your setup.
