The CST TF1 Precision Bolt Action Receiver

The CST TF1 bolt action receiver incorporates ground breaking innovations making it the most advanced bolt action design to date. Rather than emulate century year old technology, the CST TF1 has been engineered specifically from the ground up to provide the most accurate shooting platform obtainable.

As with other competition grade receivers, theTF1 is machined from premium materials to rigid geometric tolerances. What truly sets the TF1 apart however is a smarter design eliminating flaws of conventional bolt action rifles.

Cone-Loktm Bolt:

The heart of the TF1 design’s accuracy potential lies with the cone shaped locking lugs and the cone shaped floating bolt handle. Both the locking lugs and bolt handle are matched to precision conical seats machined in the receiver concentric to each other and center of bore.

Upon bolt lock up, the floating bolt handle becomes pressurized to force both the rear and front of the bolt to seat dead center and square every time, regardless of bolt diameter fit or wear. With this system, pressure to all locking lugs is maintained even after the sear is released when pressing the trigger.

• Cone-Lok™ bolt design utilizes cone shaped locking lugs and a cone shaped floating bolt handle forcing both the rear and the front of the bolt to seat dead center and square upon closing the bolt. Continuous and uniform pressure of all locking lugs is maintained even during firing pin travel.

• All models feature a zero-lift cocking piece. Flanges extending from the sides of the cocking piece ride in a precision T-slot machined in the tang of the action body preventing upward lift of the firing mechanism during bolt lockup. As a result, bolt lift caused by an angled sear engagement is eliminated.

• 3 lug design with 60-degree bolt throw with dual-cam cocking mechanism for easy bolt lift available in right or left hand configurations.

• Rear-magnetized .062” firing pin tip maintains contact with the firing mechanism while floating inside the bolt bind-free. Firing mechanism is easily field stripped from the bolt by hand, with no special tools needed.

• Angle-Block™ bedding system is standard on SCP and SBR models. Rather than a double action-screw design with small pillars, the Angle-Block bedding system utilizes three large bedding blocks housing a total of six angle-entry action-screws.

• SCP and SBR models feature full- length integral picattiny, Anschutz dovetail, or Kelbly style scope base with optional long-range tapers available.

• SCP and SBR models both feature integral parallel to bore recoil surfaces, with an optional full 180-degree wrap-around recoil lug available for SCP models. Axial recoil surfaces are designed to negate recoil energy in the same plane as its source.

• All models are supplied with trigger hangers fully adjustable for setting correct firing pin travel and detachable through trigger guard slot.

• Floating ejector button will not influence a chambered cartridge and allows manually controlled ejection force.

• Traditional easy to use mauser style bolt release does not contact bolt lugs eliminating damage to critical lug surfaces during hard retraction.

• SBRR models feature a round action body design for glue-in bedding applications.
