Vintage Truglo Red Dot - Crossbow

Listed is a vintage truglo red dot meant for attaching to crossbows. For an older optic, battery life is very good and glass is still crystal clear. Has brightness settings 0-11 making it versatile during day or night.  The reticle consists of 3 dots placed vertically. (Photo is distorted from what you see with naked eye, the reticles appear much larger) The red dot has vertical and horizontal adjustments. In my experience, the dots are meant for 20 yard increments.
