Overview

The Springfield Hellion 18-inch rifle stretches the VHS-2 bullpup formula for shooters who want more velocity and sighting radius without moving into conventional rifle overall length. It keeps the same STANAG magazine compatibility, reversible ejection, M-LOK handguard, integrated flip-up sights, and 5-position stock as the 16-inch model.

For accessories, the 18-inch Hellion uses the same core upgrade path as the 16-inch gun: bolt release, trigger-pack work, buttpad or stock geometry, sling, optic, light, and STANAG magazines. The longer barrel makes LPVO and general-purpose setups more natural, while the bullpup layout still keeps overall length shorter than many conventional 16-inch rifles.

Key Features

  • 18-inch CMV Melonite barrel, 1:7 twist
  • Full-length Picatinny top rail with integrated flip-up sights
  • Polymer M-LOK handguard
  • Feeds from STANAG AR-15 magazines
  • Reversible ejection without extra parts or tools
  • 2-position adjustable short-stroke piston system
  • 5-position adjustable stock with cheek riser
  • 1/2x28 threaded muzzle with 4-prong flash hider

Pros

  • +More 5.56 velocity than the 16-inch model
  • +Still compact because of the bullpup layout
  • +Accepts the same Hellion-specific accessories as the 16-inch gun

Cons

  • −Less compact than the original 16-inch Hellion
  • −Factory trigger still benefits from aftermarket work
  • −Premium rifle price with a smaller aftermarket than AR-pattern hosts
