Blaser exchange barrel R8 standard

The Blaser R8 interchangeable barrel is manufactured in the standard version with a barrel profile of 17 mm at the muzzle. The caliber selection for the R8 exchange barrels is enormous.
Blaser distinguishes between different caliber groups: .22LR, Mini, Standard, Medium, and Magnum.The reason for the classification of the barrels is the modular Blaser principle. The Blaser R8 systems and stocks can be individually combined with different barrel types in various calibers. Only when changing the caliber group is it necessary to additionally swap the bolt head/chamber at the bolt.
The Blaser R8 barrels in the standard barrel profile are available in different barrel lengths: 42 cm, 47 cm, 52 cm, 58 cm, 65 cm. Additionally, the barrels are manufactured with and without barrel threads M15x1. There is also the option of whether the barrel is delivered with or without sights.
The Blaser R8 barrels are cold forged and are characterized by high precision and durability. The barrels are also plasma nitrided, meaning that 0.1 mm of the surface is hardened in a special process. This creates a hard outer shell while leaving a soft steel core inside. This results in each barrel vibrating optimally and shooting very precisely. To protect against corrosion, the Blaser exchange barrels are additionally blued. The barrel steel used by Blaser is also a strong example of the company's innovative strength. The composition of the steel alloy was developed over 30 years ago in collaboration with the University of Applied Sciences Kempten and is considered one of the best-kept secrets of the Blaser company from Isny.
