Overview

This two-piece drop-in handguard is designed to replace a standard clamshell setup on AR-15 carbine or mid-length rifles, giving the platform a slimmer profile and a more ergonomic feel. Six sides of M-LOK attachment points provide space for accessories, while the built-in handstop adds a practical touch for control and hand placement. Durable composite construction and a stamped aluminum heat shield round out the design for users who want a straightforward upgrade without changing the basic handguard format. It also fits both round and triangle handguard caps and is offered in standard color options, including Coyote Brown.

Considerations & Trade-offs

  • This is a two-piece drop-in handguard, so it is intended to replace standard clamshell-style handguards rather than a free-float setup.
  • M-LOK attachment points are provided on six sides, but the handguard itself does not include accessories and any setup will depend on what you choose to mount.
  • Carbine and Mid-Length versions differ in length and weight, so fitment and balance will vary by rifle configuration.
  • The built-in handstop and slim diameter may suit some users well, but the profile is a specific design choice rather than a universal preference.
