Armaspec ARM621-3 Arca Rail 3-Inch M-LOK Adapter

Armaspec Arca Rail Adapter

The Armaspec ARM621-3 bridges the gap between modern M-LOK handguards and Arca-standard mounting systems. This straightforward solution lets you attach Arca-compatible accessories—bipods, monopods, and other gear—to your existing rifle setup without replacing your handguard.

Key Features

• Arca-Standard Interface: Full compatibility with Arca-style mounts and accessories
• M-LOK Integration: Mounts directly to M-LOK slots on AR-15 and AR-10 handguards
• Durable Construction: Black anodized aluminum resists corrosion and wear
• 3-Inch Length: Provides adequate mounting surface for stable accessory attachment
• Quick Installation: Simple, tool-free mounting to existing M-LOK rails

Practical Application

Whether you're setting up a precision rifle, tactical carbine, or hunting platform, this adapter solves a common compatibility problem. Install it once and enjoy the flexibility of Arca-compatible accessories without compromise. The rigid aluminum construction ensures your mounted gear stays put under recoil and field use.

A smart choice for shooters who value modularity and don't want to overhaul their existing handguard setup.
