Bushnell 731303 用户手册

The Bushnell® TRS-25 is a small, light and rugged red dot sight, designed for 

use on shotguns, rifles and handguns. It is constructed and assembled by 

highly skilled craftsmen to Bushnell’s high quality standards. The precision 

and craftsmanship with which this scope was built ensures its performance 

under demanding conditions. This scope will provide the shooting accuracy 

and repeatability which have made Bushnell legendary.

This sight can be easily used with both eyes open (eye relief is unlimited), 

increasing the shooter's awareness of the surrounding environment and 

providing faster target acquisition. There is no need for centering, due to the 

parallax free design in which the dot follows the movement of the user’s eye 

while remaining fixed on the target. The TRS-25 delivers full size performance 

in a sight with reduced size and low power consumption.

The model# AR731306/AR731306C versions of the TRS-25 include a tall riser 

block (D, pg. 2) to position the sight at an optimum height on AR-15 flat tops 

or tactical shotguns.

All red dot sights have an objective lens at the front of the unit that is 

spherical in shape.  However, unlike a conventional riflescope with all lenses 

mounted perpendicular (at a 90 degree angle) to the axis of the tube, the 

when looking at the sight (see below). This angle of the front lens allows the 

light generated by the battery powered LED light source inside the unit to 

be reflected back into the sight. The reflected light becomes the “dot” or 

aiming reference that the shooter sees when a red dot sight is switched on. 

This engineered “bending” of light is what makes today’s red-dot sights so 

popular and easy to use.
