The original AR rail system and the one used by militaries and law enforcement agencies around the world. Scopes, grips, lasers, lights, handguard covers, and more can all be readily mounted to these rails. Because this design is so successful, many AR rifles come with Picatinny rails molded onto the upper receiver to accept sights and scopes. Despite the practical nature of the Picatinny rail system, it’s not always the most comfortable to hold. That’s why we’ve designed a line of custom Picatinny rail accessories and covers that are practical and look awesome.

You can find custom AR parts, add-ons, and handguard accessories for Picatinny AR rail systems at AR Customs.
