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
Sight Picture &Alignment
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

Lens
LED
Holographic Sights
Differences VS LED
• Reticle Etched into Glass
• Incredible Battery Life
• Polarized Light
• Recoil Resistant
• Zero Parallax Error
• Can be Costly
– $80 to $1000+
• May Not Fit Handgun

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 LED 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
