What’s a Red Dot?

• A firearm aiming device

– Quick Target acquisition

– Quicker Aim Target

• Internally projected

reticle(s)

• Does NOT project like a

laser

• Good at all light levels

• Increasingly used on

carry guns

History

• Introduced in 1960 by Burris

– Bullseye Pistol Scope

– Black Dot Reticle

– Heavy

– Poor in Low Light

• Swedish “Aimpoint” – 1975

– “Electronic”

– Expensive

– Heavy

History

• UltraDot – late 1980s

– Mediocre copies of Aimpoint

– Affordable

• Tasco (Florida)

– Japanese Manufactured

– ProPoint - tubular

– Tag Line: Mount. Shoot. Gut. Eat. & Repeat.

– Very Affordable, Next Step Forward…

Internal Design

• Reticle projection

– R = Reticle

– CM = Collimating Lens

Internal Design

• “Tube” Version DesignZeroing

Tube vs Reflex

Tube

• Heavier

• More Robust

• Rail Mounted

• Filters

– Shade

– Polarizing

Open (Reflex)

• Smaller

• Lighter

• May be Slide

Mounted

• More Susceptible to

Reflections

Parallax

• ALL Red Dots have Parallax Error

– No error at design point – 75+ yards

• Minimization of Parallax Error

– Mount Scope as low as possible

– Collimating Lens Design Optics

– View in line with barrel

Definition: An apparent change in the direction of an

object, caused by a change in observational position that

provides a new line of sight.
