Eotech 300BLK XPS-2 Review

300 Blackout is a cartridge that came on the market and found a unique home. While boutique cartridges can come and go 300 Blackout has had staying power. One of the reasons for the 300 blackouts success is it performs excellent both suppressed and supersonic.

For those guys who love the black rifle but want a heavier, larger bullet in the 30 caliber family, the supersonic version is a big winner. For those of us in Michigan who can take deer with a rifle, a 300BLK will meet the DNR requirements. It also has been a proven beast in the hog hunting arena, where it is being used widely.

For those guys who are open to NFA items like SBR’s and suppressors, you can build a quite hard hitting CQB or plinking rifle that is 1 or 2 stamp. Since I am poor after leaving my job to focus on 248Shooter and GAT Daily, my 300 Blackout is on a pistol with the Shockwave stabilizer brace we reviewed a few weeks back.

The big problem with a gun this versatile is switching from super to subsonic ammunition will move your zero. When looking at a gun that so commonly goes back and forth from one type of ammo to another it becomes bothersome to either adjust all calculations or re-zero constantly.

Eotech solved this problem when they created the dual zeroed XPS2-300 for the 300 Blackout caliber in both super and subsonic.

Reticle:blkout ballistic data for logo

The XPS2-300 offers a 2 dot system inside the well known Eotech ring and dot reticle pattern.

The top dot represents 50 yards at subsonic and 100 yards at supersonic

The second dot is 150 yards at subsonic and 300 yards at supersonic.

The 2 dot system does not support the bottom of ring 7 yard zero that many have come to enjoy from Eotech.

The holographic “dot” is not designed to be used with night vision, which will affect some hog hunters. It is highly adjustable in brightness, however, from a very faint dot for low light (dusk), all the way up to extremely bright for use in full sun. I have used it both low light and full light and when properly set had no issues with losing the “dot.”

Eotech is one of those optics companies you either love or hate. There are few that sit in the middle. Part of that is due to the technology used. While Eotech and their competition use the term “dot” that is misleading.

Eotech is the only company that produces a laser induced hologram. Their competitors in the “red dot” market all use small red lights. The result is that a red light can only produce a dot. A laser can produce multiple dots, halo’s, lines numbers and so much more. Take a look at the XR500, FN303 or Biohazard reticles to get an idea of just how different a hologram is vs. a red light.

The holographic image is also easier for some users to use when shooting with both eyes open. The hologram visually appears on the target making a single focal plane for the eye, where a dot will be more like a front sight post, causing the eye to have to pick a focal point.

The flip side of this is holographic lasers take more energy to run requiring larger batteries that will burn out faster than LED solutions. The XPS2-300 runs for 600 hours versus the 6000 hours a T2 can run. Leaving the XPS-2 on for a month in your safe or trunk would kill your battery whereas the advertised multiple years of the competition if it did not have an auto shut off feature. Eotech has built in two different auto shutoffs to prevent accidental drain. If you turn the optic on using the up arrow you will have 8 hours of use from the last time the adjustment arrows are touched. Using the down arrow the optic will shut off after 4 hours of adjustment inactivity.

The larger CR123 battery is easy to replace and for most of us is a very common battery. All of my lights run 123’s as do some of my lasers. So the 123 is a battery I already keep in my range bag and even in a roll out kit. It is also a good bit cheaper to replace than some of the “watch” batteries used by many optics.
