 CZ Shadow and CZ Shadow 2 barrels. We are now taking orders for them.


!!! Sig Sauer P320 barrels now available. Check out our Sig Sauer page to orders yours !!! 



Unfortunately we no longer are going to be able to fit any barrels to the 1911 Rock Island Armory line of firearms. Regretfully we have recently ran into guns that are so far out of spec in areas, that we are un-willing to attempt a barrel fitting. We do apologize for any inconvenience that this may cause. We are not by any means saying anything bad about RIA, just that we have run into some issues and will no longer be able to work on them. 

Due to the nature of some of the liberal laws in a variety of states, we will not be selling threaded barrels to our customers in the following states;


  • California
  • Connecticut
  • Hawaii
  • New York
  • District of Columbia 
We certainly do apologize for any inconvenience that may arise from this. Also, before ordering a threaded/ported barrel, it would be wise to check your local statutes to make sure that there are no requlations pertaining to the use and/or posession of such things. We cannot be responsible for anyone that knowingly, or unknowingly breaks the law. 





Please be aware that all of our barrels, with the exception of Beretta's and Browning High Power's, do take approximately 6-8 weeks to manufacture from DATE OF ORDER. These times are approximate and can possibly take more or less time. -Thank You-

About us:

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".

What to expect:

*** Please allow a MINIMUM of 6-8 weeks unless otherwise posted on product page. from the date of your order before it is ready for shipment. Due to the high volume of orders that we receive. We do have cancellations and this adds to our in stock list so check there as we do add to that weekly*** we reserve the right to refuse service to anyone for any reason.

Bar-Sto is proud to be a Law Enforcement Distributor for Springfield Armory.

We are running about 16 to 18 weeks min. on our full house firearm building at this time. Please understand there is only one person doing ALL the gunsmithing at this time and we are very busy. We appreciate your business and patience!!

Please Note:  We do not ship out of the United States.
