Looks sharp on a stainless build
Reviewed on April 17, 2026Verified with Build

Picked this over a melonite tube because I wanted the stainless look. Polished finish matches well next to a stainless barrel. Pin holes lined up first try, took maybe 5 minutes to install with the gas block. Functionally its a gas tube, cant tell the difference once its running.
