Bar-Sto Barrels

Shoot for the top. If you are looking for a match level pistol barrel that’s been machined from solid stainless steel bar stock, look no further than Bar-Sto Barrels. Bar-Sto Precision Machine is a company that’s been manufacturing the pinnacle in auto-pistol barrels for over four decades. The barrels are still machined and rifled right in the top-of-the-line shop. The company’s client list reads like an impressive “who’s who” in the shooting world. The U.S. Marine Corps Marksmanship Unit has relied on Bar-Sto barrels for years. The competitive shooting organizations of the U.S. Army, National Guard and Air Force also use this invaluable brand of barrel. Special Operations personnel rely on these gun accessories and other Bar-Sto products. Pistol champions have taken them to wins in major tournaments around the globe, including the NRA National Outdoor Rifle & Pistol Championships, U.S. Practical Shooting Association Nationals, Steel Challenge, and others. Take a cue from some of the most accurate shooters in the world who buy and use Bar-Sto.

At Top Gun Supply, you can buy a semi-drop in barrel from this premier maker. With “semi-drop in,” you can expect little to no additional fitting required. However, guns are unique pieces of equipment, and some fitting may be needed. Bar-Sto’s goal in machining these barrels is to give a tighter lock up for specialized accuracy that goes beyond the factory barrel. We sell the conversion barrels in stock length, as well as the 9 mm replacement barrel with fully supported chambers so you can shoot higher quality reloads or lead bullets if you want that option. Convert a Sig or replace a Glock barrel for preferred performance at a reasonable price, with Bar-Sto and Top Gun, your well-stocked gun store.
