According to X2 Dev Group, Trident barrels, guaranteed Sub-MOA with quality ammunition, exhibit extreme rigidity ensuring consistency and minimizing POI shift when mounting suppressors. This is due to specially timed flutes that act as opposing I-beams, providing structural integrity with reduced mass to maintain optimal barrel harmonics. Keeping all the performance of a 416R Stainless barrel, this design sees weight fall under that of leading carbon fiber barrels. Trident barrels are nitrided, impregnating the steel unlike coatings, for corrosion resistance and improved barrel life.
X2 Dev Group makes all Trident barrels in-house, optimizing the heat profile for consistent group dispersion through 473 degrees Fahrenheit, distributing the heat evenly to reduce heat soak and stress, which, combined with added rigidity, enhances POI predictability through longer strings of fire.
Trident barrels use a .750” journal and are available on X2 Dev Group’s website with a low-profile fixed gas block, a Superlative Arms adjustable gas block, or ready to accept the gas block of your choice. All Trident barrels feature M4 Feed Ramps, a 1/2x28 threaded muzzle, and are chambered in .223 Wylde with a 1:8 twist rate.
