The new TRS-125 is a compact enclosed red dot with high and low mounts with modern features and battery life that shooters and hunters need.
The TRS-125 features an efficient and clear 3 MOA dot with 10 brightness settings that delivers up to 15,000 hours of battery life. The point source LED creates a clean beam that produces a strong day light-bright dot without wasting energy. 
Push-Button controls not only give you the option of 10 brightness settings, but also give you the ability to engage or disengage the 12-hour automatic shutoff should you want to use it for defensive purposes. When on, the onboard timer automatically turns the unit off after 12hrs of no buttons being pressed. When off, the optic stays on until you shut it off. The optic’s onboard logic makes it easy to determine what state the optic is in; 4 quick dot pulses to indicate the timer is active or 3 slow pulses to indicate off. 
The TRS-125 comes with a low profile Weaver-style mount and a high-rise spacer, is IPX7 waterproof.
