Description
Our .223 Semi-auto barrels are proven winners!
All our barrels are cut in the best GBQ (Gun Barrel Quality) 416R stainless steel and rifled with 5R rifling. Every barrel that leaves IBI is double stress relieved, honed to within .0001″ from end to end AND hand lapped to ensure the best accuracy possible.
We chamber them with a .223 Wylde chamber. Standard twist rate is 1/8″. Custom twist rates can be ordered. Muzzle threads are included (1/2-28). From 14″ to 20″ or more and in a variety of profiles, calibers and weights, you can be sure that your AR will run the best with one of our barrels on it.
