Vector Optics Centurion 1x20 RUM Red Dot Sight — Black

The Centurion 1x20 is a closed-tube red dot sight by Vector Optics designed for use on firearms in operational, defensive, and hunting contexts. The integrated RUM (Rapid Universal Mount) mounting system makes it compatible with standard Picatinny rails without the need for separate mounts, reducing height and bulk on the rail.

With a fixed magnification of 1x and a 20 mm objective, the Centurion sits in the compact red dot category: the smaller window supports fast target acquisition at close range and keeps the weapon profile low, but it is not the right choice for those who need a wide field of view at medium distances. It is a deliberate trade-off: you gain responsiveness and compactness, but give up the extended field of view offered by a 25 mm or larger objective.

The closed-tube construction protects the electronics and lenses from dust and moisture under demanding conditions, unlike open red dot sights which offer a lower profile but leave the optics exposed to the elements.

Key Features

• The integrated RUM mount eliminates the need for a separate riser or mount, lowering the sight line and reducing overall setup weight.
• The compact 20 mm objective makes the Centurion well suited to carbines and short-barrelled rifles where rail space is limited.
• The closed-tube construction provides dust and moisture protection without additional accessories.
• Fixed 1x magnification allows use with both eyes open, maintaining full situational awareness during rapid target acquisition.
