GrovTec GTSW238 3.8" M-LOK Rail Section - 9 Slot Black Anodized

The GrovTec GTSW238 transforms any M-LOK handguard into a versatile mounting platform with nine precision-machined slots. This 3.8-inch rail section provides reliable attachment points for accessories while maintaining the streamlined profile that makes M-LOK systems superior to traditional quad rails.

What Makes This Different

Unlike generic rail sections that add unnecessary bulk, the GTSW238 features a low-profile design that extends only where needed. The black anodized finish matches most factory handguards, while the Type III hard coat provides superior wear resistance compared to standard aluminum finishes. Each slot maintains precise spacing for consistent accessory alignment.

Key Features

• Nine Picatinny slots in compact 3.8-inch length for maximum versatility
• Type III hard anodized black finish resists wear and corrosion
• 6061-T6 aluminum construction provides strength without excess weight
• Compatible with all M-LOK handguards and forends
• Beveled edges prevent snagging on gear or clothing
• Includes stainless steel mounting hardware
• Low-profile design maintains handguard aesthetics

The GTSW238 handles demanding applications from competition shooting to tactical operations. The precision-machined slots ensure accessories like bipods, lights, and grips lock securely without shifting under recoil. Weather sealing around mounting points prevents moisture intrusion that could compromise the M-LOK connection. The anodized surface maintains its appearance through thousands of rounds and harsh environmental conditions.
