Since 1953, Hart Rifle Barrels have been preferred by the most discriminating rifle shooters.
Every Hart Rifle Barrel is guaranteed to have a groove dimension tolerance of +.0005" (For example: a .243 caliber can range from .2430 to .2435). The groove will not vary more than .0001 from breech to muzzle.
Every Hart Rifle Barrel is measured with an air gage and examined with a borescope to ensure that there are no tool marks or other defects that will affect accuracy.
Hart Barrels are hand-made from only the highest grade of stainless steel (416R). Our barrels are button rifled with six grooves. While many gun makers use "seconds,” our scraps are sent to a recycling plant.
Every barrel that leaves our shop is individually inspected several times to make sure it meets our high quality that will affect accuracy. standards.
Each Hart Rifle Barrel is contoured on a CNC lathe, then hand-lapped to ensure the best possible interior finish.
All sizes are +/-.005
