The Tactical Heavy Barrel or THB is one of the most popular rifles produced by Steyr, and comes packed with exclusive features not found on rifles of lesser quality. It comes equipped with a ventilated, glass-reinforced polymer stock which is exceptionally durable and highly weather resistant. Its cold-hammer forged barrel is available in lengths of 16”, 20”, 26” and features a Mannox finish. The barrel also has Steyr’s signature swirl pattern, a distinctive and attractive byproduct of Steyr’s cold hammer forging process. The muzzle of the barrel is outfitted with a 5/8x24” Right Hand threads for the installation of muzzle brakes and suppressors, and a screw-on thread protector is included as well.

Other aspects of the THB include the Steyr exclusive Safe Bolt System or SBS. This system offers a unique 2+1 safety system which is operated via wheel switch on the stock’s tang. The first safety mode disables the firing mechanism, the second level locks the bolt, and the fire more is indicated by a red dot. The THB’s magazine has a unique 2-stage magazine securing system. The first stage locks the magazine in place but won’t chamber any rounds. This lets the shooter load individual cartridges by hand while still having a full magazine at the ready. Tapping the bottom of the magazine will engage the second stage and allows chambering by the bolt. As with all of Steyr’s bolt action rifles, the THB has a sub-MOA guarantee.
