Top Features of the Strikefire 2 Red Dot Sight


The Vortex Strikefire 2 is constructed from a single alloy aluminum billet.  From the single billet, a 30mm lightweight solid single-piece chassis is formed. The results are a 7.2 oz optic that is strong enough to withstand the bangs and bumps you will encounter during range and hunting days.

The 30mm tube allows for a large Field of View (FOV).  The red dot sight has a matte finish hard anodized coat that reduces glare for a low shooter signature. Filled with argon gas and sealed with o-rings, the Stikefire 2 is protected from dust and moisture. The optic is also fog-proof through a wide range of temperatures.  This sight is suitable for operation in almost all environments.

The Strikefire II red dot sight has an overall length for 5.6 inches with a 1.45-inch objective lens (36.8mm) and a 1.8-inch eyepiece lens (30mm).   The size and compact design of the sight is ideal, allowing for ease of maneuver and unimpeded employment.  This red dot sights overall size and design allow for smooth and snag-free target acquisition and transition.


With the Vortex Stikefire II, you get two reticule color options all within one sight.  You can select a 4 Minute of Angle (MOA) red dot option or a 4 MOA green dot option. This is a great feature as some shooters prefer a green dot reticle for specific light and environment conditions and a red dot reticle for daily use.  You will find the 4 MOA reticle is suitable for close to intermediate range engagements.

If you require an AR specific application for more precision at extended distance engagements, then take a look at our review of the Vortex Spitfire 3X Prism Scope.

This red dot sight has ten illumination brightness settings. The two lowest settings are night-vision compatible.  Adjustments to the reticle brightness are made via two rear-facing side-mounted buttons. Additionally, this sight includes an automatic shut down after 12 hours.


The Strikefire is powered from a single CR2 Lithium battery. If you factor in the 12-hour automatic shutoff, you can expect a battery life of up to 7,000 hrs at lower settings. The battery compartment is easily accessible for quick battery changes.

The sight is easy and intuitive to operate.  All functions are controlled with two side-mounted rear-facing buttons. Press and hold the UP button to turn the sight on/off. Press and hold the DOWN button to change reticle color.  The same buttons are used to adjust the reticle brightness.  This simple design in operation procedures makes the sight one of the easiest you will ever use.

Elevation and windage adjustments are made by removing the turret cover and adjusting the turrets in the proper direction with a coin or a screwdriver.  Adjustment increments on this red dot sight are in ½ MOA.  A single click adjustment on the Strikefire 2 will move the point of impact ½ inch at 100 yards.  The ability to make ½ MOA adjustments allows for increased precision.


Included with your purchase of the Vortex Strikefire 2 is a cantilever mount that will mount on a Picatinny or Weaver-style rail base.  Utilize this mount will place the optic bore center 40 mm above the base. If you are mounting the red dot sight on an AR-style platform, you can expect to achieve a lower 1/3 co-witness with the existing iron sights.

If you need to mount your Stikefire II at a different height, you will have to purchase a different 30mm ring mount.

Pros vs. Cons of the Vortex Strikefire 2 Red Dot Sight

The Pros 

The optic is intuitive and easy to operate right out of the box. Every level of shooter will have no problem putting this red dot sight into action and getting great results.

 You can switch between a red or green dot reticle.  We have found that in some conditions, a green dot is much easier to acquire.

The Vortex Strikefire 2 Red Dot Sight twelve-hour auto shut off feature is perfect for ensuring an extended battery life.  

The Vortex Lifetime warranty is better than many others in the industry. The warranty covers both physical damage and damage to the electronics.

The included cantilever mount frees up space on your mounting rail. This is a great feature if you expect to mount several other items like a magnifier, laser, or flashlight on your firearm.

The Cons

If you enjoy a larger reticle, then this might not be a con for you. Unless you expect to use the optic for close-range engagements, the 4 MOA dot may be a little large for precision shooting out to intermediate distances.

The battery life for the Strikefire 2 could be better for a sight at this price point.

Another feature that could make this red dot sight better would be auto-on.
