Eventually, enterprising gunsmiths incorporated the Picatinny rail into handguard designs. One of the earliest designs featuring a Picatinny rail was the upper receivers on M16 rifles and M4 carbines, giving them an easier option to mount optics. Picatinny Arsenal in New Jersey completed and standardized the design in the 1990s. In the 1980s, companies trying to standardize the Weaver design created the Picatinny rail. Picatinny rails are the oldest design of the three. All three designs use interface systems for mounting sights, optics and accessories. Three main options exist for rail designs: Picatinny (also known as MIL-STD-1913 Rail), Keymod and M-LOK.
