Overview

Designed for AR-15 builds centered on suppressor use, this 6.7-inch RG2-S handguard is intended to provide a compact, purpose-built platform with M-Lok accessory mounting. Its wedge block locking system is described as applying even pressure around the barrel nut, which is meant to support a more secure attachment when the front end is loaded with a bipod or sling. The skeletonized design keeps the profile streamlined, making it a practical option for hunters and shooters building a shorter setup with room for quick-attach suppressor mounting solutions.
