Each is compatible in single pin, Double Pin, 3, 5, or 7 pin MRT guard.NEW for 2017 MRT pin guard Introducing the newly redesigned multi-pin guard featuring the Multi-Ring Technology (MRT). The MRT housing is available now in 3 or 5 pin configurations with a 7 pin option coming soon. 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.
