Overview

This two-piece drop-in handguard is designed for Carbine or Mid-Length AR-15 setups where a slimmer profile and added attachment options are useful. It replaces the standard clamshell style with a composite build, a built-in stamped aluminum heat shield, and six sides of M-LOK attachment points for mounting compatible accessories. The integrated handstop and reduced diameter support a more secure grip, while compatibility with both round and triangle handguard caps adds flexibility during installation. Available in OD green, it is a practical option for hunters and shooters who want a straightforward handguard upgrade without changing the basic platform layout.

Considerations & Trade-offs

  • This is a two-piece drop-in handguard, so it is intended to replace a standard clamshell setup rather than a free-float system.
  • M-LOK attachment points are provided on six sides, but the handguard itself is still a compact carbine or mid-length format with a fixed 1.75 in. width.
  • The built-in handstop and slim diameter may improve control, but the shape and integrated features are part of the design rather than a fully customizable platform.
  • It is offered in carbine and mid-length versions, so fit depends on matching the correct length to the rifle setup.
