The MDT JAE Adjustable GEN2 Black Bag Rider (114679-BCG) is a precision rear support accessory designed to enhance rifle stability during prone or bench shooting. Crafted from hard-anodized 6061 aluminum, it features a sleek boat-shaped profile that glides smoothly through rear bags, minimizing friction and improving shot consistency. Its slim design allows bag material to settle naturally around it, helping maintain a steady reticle. With 0.75 inches of forward and backward adjustment, it fits JAE Gen 4 and Gen 5 chassis systems without interfering with buttpad or length-of-pull settings.
