Named for the unique design, the KeyMod rail system is an open-source design meaning that anyone can make accessories and attachments for KeyMod handguards. This makes them a popular choice for AR rifle owners. The self-aligning design makes it easy to quickly attach and secure your accessories, rail covers, and more. KeyMod rail systems are slim and lightweight, making them ideal for those looking to set up an ultralight AR15 shooting platform.

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