From Alaska to Arkansas to Arizona, the Model 70 Extreme Sporter MB is built to provide extreme accuracy legendary dependability in the toughest hunting conditions. Like all Model 70s today, it features the Pre'-64 type claw extractor with Controlled Round Feeding so the cartridge may be easily withdrawn from the chamber at any point after it leaves the magazine. It also means that the cartridge base is grabbed by the claw as it leaves the magazine so it enters the chamber straight, in line, to minimize damage to the bullet tip. The cartridge feed lips are machined as part of the receiver for improved feeding reliability. The classic Three-Position Safety offers both on safe and fire positions, plus a middle position that locks the firing pin yet still allows the bolt to be operated, providing a greater margin of safety when checking the chamber condition or unloading. The free-floating, fluted barrel has a recessed target crown to protect the rifling. 9/16"x24 threads at the muzzle for allow the attachment of the radial muzzle brake. The fluted barrel allows provides a stiffer barrel profile, with greater surface area for cooling, and does not carry excessive weight. The Extreme Sporter MB feels very light but offers accuracy of a heavier rifle. With quality optics, premium ammunition, and good shooting conditions, 1 MOA accuracy can be expected — if you, your ammo and your optics are up to it.
