This Springfield Armory Hellion Bullpup chambered in 5.56 NATO is a compact, modern rifle platform with a full-length barrel packed into a shorter overall package. The black finish, M-LOK handguard, full-length top rail, adjustable stock, and ambidextrous-style controls give it a very practical setup for range use, training, and collectors who like unique bullpup designs.

This package is upgraded with a SIG SAUER Bravo4 4x30mm prism optic mounted on the top rail. The exact SIG model should be verified, but it appears to be from the SIG BRAVO-style prism/battle optic family. The rifle also includes the Springfield Armory soft case, manual/paperwork packet, magazine, and lock shown in the photos.

Springfield lists the Hellion 5.56 with a 16" CMV Melonite barrel, 1:7 twist, black finish, adjustable gas system, integrated flip-up sights, and included padded rifle case. This example appears to be in excellent overall condition with only light handling visible.
