(1) The receiver is machined from 17-4 stainless steel to true benchrest quality standards. The design features a solid top with a trim loading port. This increases action stability, stiffness, and strength. The loading port is easily accessible and is angled to aid the shooter in single loading rounds. The TUBB 2000 is fed via 10 or 20-round box magazines.
(2) Low effort bolt operation was a key goal in the design of the TUBB 2000 action. The exclusive bi-camming design employs two cams that engage during bolt lift to radically reduce bolt lift effort. Bolt lift is 75 degrees. In conjunction with the receiver's helical cut cocking cams and the coned faced bolt, the TUBB rifle offers one of the smoothest operating actions ever built.
The bolt handle is designed for superior performance in sustained fire operation. Its ergonomic shape allows operation with a single finger, if desired.
The hardened bolt is machined from 9610 carbon steel and rides back into the stock extension, under the shooter's face so the bolt can be operated without the shooter having to change his head position. This low center of gravity also improves the rifle's feel and performance under recoil.
(3) The action features a full-length picatinny sight rail that will accept an almost endless array of competition sights and scope rings. The action's adjustable sight mounting system allows the sight rail to be mounted at one of three pre-set mounting angles – 0, 5, and 10 degrees – to allow the shooter to cant the rifle while shooting and maintaining a straight-up level sight. All barrels come standard with the muzzle turned down to accept a clamp-style front sight mount, barrel extension, or cant indicator.
(4) Lock time in the TUBB 2000 is one millisecond – more than three times faster than a Model 70 Winchester.
(5) TUBB 2000 rifles come standard with a hand-lapped Schneider stainless steel match barrel with the exclusive "TUBB Contour." This unique contour maximizes accuracy and minimizes weight -- it's the perfect balance. According to David: "It's a contour where the barrel wouldn't shoot one bit better if it was one bit bigger."
The TUBB 2000 is a "switch barrel" gun – it's designed to be easily rebarreled by the customer with a barrel clamping vise. A custom action wrench is available. This feature means that the same rifle can support different calibers and uses. Finished barrels in most popular short-action calibers are available for customer installation.
(6) The TUBB 2000 uses the superb Anschütz fully-adjustable two-stage trigger with safety. This trigger can also be adjusted to provide single-stage operation and trigger shoe position.
(7) The buttstock assembly, forend, buttstock clamping block, and magazine housing, trigger guard assembly are made from 60-series aluminum, hard anodized in matte black.
(8) The buttstock is fully adjustable for length, height, cant (angle), and offset. The cheekpiece is adjustable for height. An easily accessible knurled wheel allows the shooter to adjust the cheekpiece from the shooting position. Shooter comfort is further augmented by an ergonomic pistol grip. All adjustment features on the TUBB 2000 were designed for easy shooter access. The stock extension, clamping block, butt extension, and buttplate all have index marks to allow the shooter to record and repeat adjustment settings.
(9) The tubular forend can be rotated to coincide with the cant position of the sight rail to maintain the shooter's comfort. The forend slots accept the custom designed adjustable handstop or optional bipod. The forend also incorporates a built-in barrel heat wave blocking system which eliminates optical distortion in the sighting plane.
(10) The TUBB 2000 disassembles easily and can be transported in two pieces. Its all-metal design and precision-made parts mean there is no zero change resulting from reassembly. The TUBB 2000 is unaffected by temperatures and weather conditions and is also very rugged and durable in the field.
