The J&E Machine Tech Polymer KeyMod Rail (brand part no. PS-HGKMR2) adds Picatinny rail sections wherever a KeyMod handguard needs one, without the weight or cost of an all-aluminum rail. Each 4″ section is molded from black polymer and offers 7 slots of rail space, and the set ships as a 2-pack so a shooter can outfit both sides of a handguard — or add a top and bottom section — in a single order. These sections clamp directly into any standard KeyMod slot, giving quick mounting points for lights, lasers, or other Picatinny-compatible accessories.
