The B& T BT72-NC Super CAL Atlas Bipod, paired with the Area 419 ARCALOCK QD Clamp, is engineered for shooters who demand the ultimate in stability, speed, and compatibility with ARCA rail systems. Purpose-built for large-frame rifles and heavy-duty precision work, the Super CAL’s extra-wide stance, cant-only leveling, and long leg extension offer superior support in field and competition environments. The addition of the ARCALOCK QD Clamp delivers lightning-fast attachment and detachment from ARCA rails, while locking into machined grooves to prevent shift under recoil. This setup is ideal for long-range shooters, PRS competitors, and military professionals who require reliable, no-compromise performance under all conditions.
