MK46 Profile or Standard M-LOK | Multiple Configurations

Drop weight. Stack options. Own the field.

The Bull Craft A&K M249 / MK46 M-LOK Handguards are lightweight, modular upgrades designed to dramatically reduce front-end weight while expanding accessory control. Built from rugged SLS-printed Nylon PA12, these 2-piece handguards deliver ergonomic handling, modern M-LOK mounting, and mission-tuned durability without the bulk of OEM systems.

Choose between the MK46-profile handguard—available with multiple top and bottom rail configurations, including an optional tripod-compatible lower—or the Standard 7.75" M-LOK handguard for classic, streamlined builds. Same materials. Same strength. Different geometry for different platforms.
