34mm Main Tube
The larger tube diameter increases the internal adjustment range, making it easier to zero in on your target and maintain accuracy at long distances. The tube is crafted from a single piece of high-grade aircraft aluminum for maximum strength and rigidity.
The Rigid Precision cantilever style mount 20 MOA provides near 2.5 Inches of forward extension for better eye relief typically desired for use on AR style platforms.
