Volquartsen Firearms 10/22 22 LR Stainless Steel Barrel with 32 Hole Comp Black. 920" bull barrels set the standard in accuracy and performance for rimfire barrels. They feature match bore and chamber dimensions and vary no more than +/0.0001" from breech to muzzle. Each barrel is digitally measured and inspected. The barrel shank is machined 0.0025" oversized to create an extremely tight fit into the factory receiver. This prevents the barrel from canting once the locking block is installed. Weve developed our unique chamber to provide optimal accuracy but also superior function.
