The gun also has a toolless adjustable gas block that has two configs, unsuppressed and suppressed.
So, we decided to put them to the test.
The Hellion iron sights are metal and spring into action with the push of a button.
The Springfield Armory Hellion provides shooters with an exceptional 5.56mm bullpup that combines compact size with impressive performance.
This is a huge plus because they are built-in and out of the way until needed.
The rear post has several different apertures.
To be exact, it has a total of five different apertures meant to be used at different ranges.
To start off, there is a 0 aperture for close-quarters use and as a night sight.
The 0 aperture in my experience does work well with CQB shooting.
I was able to pick it up quickly as I transitioned from target to target.
The author used Remington UMC FMJ223 ammunition for this article on how to use the Hellion sights. It performed reliably and delivered good accuracy.
We set up our full-size torso steel plate that is 30 tall with 18-wide shoulders.
The adjustments on the Hellion iron sights are some of the best.
Like the gas system adjustments, the sights can all be adjusted without tools.
The front post almost comes to a sharp point, providing a fine aiming point that allows for accurate shooting. When doing the initial zero, this point helps out greatly.
The front post adjusts for elevation of impact.
To raise the impact up, turn the front post adjustment counterclockwise.
This will raise where your bullet is hitting.
Aperture settings on the Hellion’s rear sight are numbered 0, 1-2, 3, 4 and 5. The numbers correspond with distance in increments of 100 meters. For example, the 3 is used for 300 meters.
The rear sight adjusts the windage.
Turning the rear adjustment clockwise adjusts the bullet impact to the left.
We were able to shoot it and hit steel at 200, 300 and 400 meters.
To zero the Hellion, use a supported position at 100 meters. Fire on a clean witness panel and begin to make your adjustments. The author used an 18″x30″ steel plate.
Final Thoughts on Using the Hellions Sights
The Hellion does have some pretty impressive iron sights.
It is truly great to have built-in BUIS on your rifle just in case you should ever need them.
