Designed to work on same-plane rail systems, Fixed BattleSights are a permanent, rail-mounted alternative to a standard A2 rear sight or carry handle sight allowing limitless mounting options on all-length rails with a serrated ramp to eliminate glare. Made of hardened T6 Aircraft Aluminum with stainless steel components, fixed M4 BattleSights provide a continuous zero and unflinching durability. It fits all M4, M16, AR15, AR10 variants and other firearms that have a flat top receiver or removable carry handle Note: Railed gas blocks higher or lower than receiver height will not zero properly.
