Many times when in the field or during competitions you need to transition between no magnification for speed at close-range and magnification for precision shooting as the situation dictates. The Athlon 5-power magnifier mounts behind a traditional red-dot sight to provide magnification when needed. The mount has the ability to swing out of the way when not in use, but can quickly be placed behind the red dot to increase the magnification for longer mid-range shots.
Key Features:

• Fully multi-coated lenses
• Nitrogen purged
• Aircraft grade aluminum
• One piece chassis construction
• Waterproof
• Fog proof
• Shockproof
