Drop in stainless steel barrel features match bore and chamber dimensions. The barrels will vary no more than +/-.0001″ from breech to muzzle. Each barrel is digitally measured to assure exact tolerances. The barrel features our unique chamber designed for optimum accuracy and functioning. A 32-hole compensator is also installed which allows for recoil free shooting. The compensator also stabilizes gases around the bullet upon exiting the muzzle for increased accuracy. In addition, the barrel features six longitudinal flutes that provide more surface area for heat dissipation, reduce weight and increase barrel rigidity for increased accuracy. 20″ overall length, .925″ bull barrel, weighs approx 3lb 1oz
The top 2 shooters at the 2005 ARA (American Rimfire Association) Nationals were shooting Shilen barrels. Here’s what Shilen states about their barrels.
Well, here are the barrels that are up to the job! Each one of these Shilen target barrels must meet our Match Grade criteria, air gauging within 0.0005″ of a special undersized groove diameter designed to produce optimum accuracy from all types of .22 ammunition. The bore also must not vary in diameter more than 0.0003″ for its entire length. These are serious barrels for serious shooters.
In addition, the barrels are stress relieved and warranted by Shilen against defects in materials and workmanship. Offered in both Chrome-moly and Stainless Steel, they are completely finished by Shilen and are ready for installation. Chrome-moly barrels are supplied blued. Stainless steel barrels come in polished white, with a hand-lapped bore.
