Bushnell have released a new reflex sight called RXM-300 which with a 28mm (1.1″) wide and 24mm (.945″) tall window is the largest open emitter red dot sight ever produced by the company. The RXM-300 sight was designed in cooperation with competition shooter KC Eusebio, however, it’s not a competition-only oriented product and is advertised as being suitable for virtually any application, from competition to self-defense. Let’s take a closer look.

Bushnell RXM-300 reflex sight has a housing made of 7075-T6 aluminum. It is IPX7 and MIL-STD-810H ingress and drop protection rated. The holes on the top corners of the housing serve as crumple zones for impacts to protect the lens and as quick reference alignment points when presenting the sight. The EXO Barrier lens coating repels water and light debris. The RXM-300 is an RMR footprint sight but it also comes with two different-height Picatinny rail risers/adapters. The overall weight of the sight only is 1.95 oz.

Bushnell RXM-300 is a parallax-free (optimized at 50 yards) sight with a 4-MOA red dot. It has 12 dot brightness settings with the lower two being compatible with night vision devices. The brightness can be adjusted manually or via the automatic Light Sensing Control mode. The sight is powered by a single CR2032 battery installed from the top of the housing and has a battery life of 35,000 hours on the eighth brightness setting. There is also an adjustable shake-awake feature. Both the windage and elevation are adjustable within the 100 MOA range, with 1-MOA click values.

The MSRP of the Bushnell RXM-300 reflex sight is $299.99. It comes with a protective cover, tools, and cleaning cloth. The RXM-300 sight is backed by a 5-year warranty.
