FAQ
Is the Hellion good for left-handed shooters?
Yes. The ejection port can be reversed to the left side in minutes, and the controls are ambidextrous. Lefties can run it without brass hitting the face.
What kind of accuracy can I expect?
With good 5.56 ammo, expect 1.5 to 2 MOA at 100 yards. The 16-inch barrel and piston system give consistent results, though bullpup triggers are not as crisp as a match AR trigger.
Does it come with any accessories?
The Hellion ships with one magazine, a cleaning kit, and a sling. Per Springfield Armory specs, it also includes a set of backup iron sights.
How does the Hellion compare to an AR-15?
The Hellion is about 5 inches shorter overall with the same barrel length. It’s heavier (8 lbs vs 6.5 lbs), but the compact size makes it easier to handle indoors. The piston system also runs cleaner than a direct impingement AR.
Can I suppress the Hellion?
Yes. The barrel is threaded 1/2x28, and the adjustable gas block lets you tune for suppressed use. Just swap the gas setting to the suppressed position.
