Finally you can enjoy rugged Spot-Hogg dependability in a freestyle sight. With our HRD technology (Hardened Rail Design) there is no slop, buzz, or babying this sight. With all the adjustability and accuracy capabilities that Spot-Hogg is known for, this sight is one tight sight. The Spot-Hogg Hogg Father features the Multi-Ring Technology (MRT). The MRT housing is available now in 3 or 5 pin configurations. 3 and 5 pin versions come with two multi-ring options, a small and large, as well as one single ring. This increased versatility ensures proper peep to sight alignment with most setups. The multi-ring options provide the archer with a much higher level of accuracy in varying lighting situations by always giving the archer a bright visible ring to align their peep to. Further upgrades include a larger, more visible level, better protected, fiber optics, and an improved lighting cavity that allows the sight light (not included) to be more evenly distributed and protects unwanted light from escaping.
