Bar-Sto Precision Machine

Bar-Sto Precision Machine has been making the finest auto-pistol barrels since 1971. Bar-Sto barrels have been used by the U.S. Marine Corps Marksman Unit since 1977. The AMU uses them also. They have also been used to win every major pistol tournament worldwide, including Camp Perry, the U.S.P.S.A. Nationals, Steel Challenge, the Masters, and many more.

All Bar-Sto Pistol barrels are machined from solid 416 stainless steel bar stock which has been heat treated 39 to 43 RC and 180,000 PSI tensile strength. Barrels are machined, bored, and rifled completely in our own shop. All barrels have a rate of twist of 1 turn in 16".
