A red dot sight – also called a reflex sight – projects an illuminated aiming dot with which you get on aim intuitively and with both eyes open. It's aimed at hunters on driven hunts, sport shooters in dynamic disciplines and authorities. It plays to its strengths wherever speed and moving targets matter.
How does a red dot sight work?
A red dot sight projects an illuminated dot onto a glass lens that appears to sit on the target – without magnification and parallax-free. You no longer switch between rear and front sight; you simply place the dot on the target and shoot. Because both eyes stay open, you keep the surroundings in view and react faster to moving game.
Which dot size in MOA suits you?
The dot size is given in MOA and determines how finely you aim: a small dot covers less and hits more precisely, a larger one catches the eye faster. As a rule of thumb:
- 2 MOA: fine aiming, covers about 6 cm at 100 m – ideal for precise shots and longer distances
- 3–4 MOA: a balanced all-rounder for hunting and sport
- 6 MOA and more: catches the eye quickly – ideal for short distance and fast shot sequences
Open reflex sight or closed tube sight?
Open reflex sights are light and give a free, wide field of view – ideal for fast handguns and slug guns. Closed tube sights fully enclose the optic and keep out dirt, snow and rain more reliably – the more rugged choice for tough conditions and large-calibre firearms.
Which model suits your use?
Depending on the application you reach for a different design. Also look for enough brightness levels – from bright midday to darkness – and a recoil-proof, waterproof build:
- Hunting sights: for driven hunts and fast shot sequences on moving game
- Sport sights: for IPSC, falling plate and other dynamic disciplines
- Tactical red dot sights: rugged models for authorities and security forces
How do you zero a red dot sight?
You adjust a red dot sight via the elevation and windage until the dot sits on the zeroed distance – usually a few shots are enough to zero it. After that you simply hold the dot on the target, without holdover correction at short distance. You match the brightness to the ambient light so the dot stays sharp and doesn't bloom.
Does the red dot withstand recoil?
For hunting and large-calibre firearms you should look for an explicitly recoil-proof build so the dot sits exactly after every shot. NOBLEX develops its sights in Germany to DIN EN ISO 9001:2015 and builds them shock-, water- and fog-proof; the approval for the respective calibre is in the product description. Using the filters you narrow down by dot size, design and use.
NOBLEX is the direct successor to DOCTER optics: the well-known DOCTER sight – called the “Docter Red Dot” by many – lives on in the NOBLEX NV sights. That's why you'll find matching accessories and spare parts for your DOCTER sight right here.
