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 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".

***As we make all of our barrels custom for each order that we receive, please allow a MINIMUM of 12-14 weeks from the date of your order before it is ready for shipment. Due to the high volume of orders that we receive, we are not able to keep our barrels "in stock" at this time.***

NEW! Bar-Sto is now a Law Enforcement Distributor for Springfield Armory Products and a competition dealer for Safariland. We have also added Airsoft products and Surefire flash lights. Look for these products on our site in the near future.
