Frequently Asked Questions
Is this barrel compatible with my existing AR-15 upper?
Yes, designed for standard AR-15 platforms, it fits most mil-spec uppers with a carbine gas system and 0.750-inch gas block journal.
What makes cold hammer forging better than button rifling?
Cold hammer forging compresses the steel for denser, stronger barrels that resist heat and stress, offering longer service life and better accuracy over time.
Does the chrome lining require special maintenance?
No, the chrome lining simplifies cleaning by reducing carbon buildup, but regular maintenance with bore solvents will keep it performing optimally.
