The Springfield Armory Hellion 5.56 NATO bullpup rifle from Springfield Armory is the California-compliant 20-inch model, with a fixed stock, a Strike Industries pistol grip and an SA muzzle brake for reduced recoil (brand part no. HL920556BCA). The action sits behind the trigger, so the 20-inch barrel fits an overall length of 31.75 inches. Controls are ambidextrous and the case ejection is reversible, allowing it to be fired from either shoulder. A short-stroke piston with a two-position adjustable gas setting drives the action, and a polymer M-LOK handguard provides mounting room. It feeds from a 10-round Magpul PMAG Gen M3.
