Zermatt Arms TL3 Proof Research PXT 6.5 Creedmoor Carbon Fiber Barreled Action (22" Carbon Fiber Sendero Profile PXT Barrel)
PROOF Research PXT pre-fit barrels combine next-generation rifling technology with the simplicity and convenience of a ready-to-install barrel system. PXT - PROOF Exponential Twist - is a complete rethinking of conventional rifling geometry and twist progression, engineered to reduce engraving force, minimize throat erosion, and create a smoother transition as the projectile engages the rifling.
By dramatically reducing rifling lead angle and smoothing projectile engagement into the bore, PXT technology helps reduce wear, improve consistency, and create less felt torque during firing for improved shooting control and the ability to stay on target more effectively.
In controlled testing, PXT barrels have demonstrated significant increases in barrel life while maintaining the accuracy standards expected from a PROOF barrel.
Our PXT pre-fit barrels arrive threaded, chambered, and ready to shoulder directly up to your action, offering shooters and builders a streamlined path to a premium rifle system without the need for additional machining. Currently available in PROOF carbon fiber configurations for Defiance, Zermatt Arms, and Tikka actions - with additional options coming soon - PXT pre-fits deliver lightweight performance, craftsmanship, and advanced barrel technology in one complete package.
Lightweight: Up to 64% lighter than traditional steel barrels of similar contour.
Extreme Temperature Resistance: Improved heat dissipation for cooler and longer lasting barrels.
Unprecedented Durability: Wrapped with high-strength, aerospace-grade carbon fiber impregnated with a proprietary matrix resin.
TL3 actions are the next generation of products from the superb Bighorn Arms lineup. The original TL actions set the standard in custom rifle actions for repeatability, ease of use by the gunsmiths, and demonstrated class leading accuracy. The floating bolt heads allow easy cartridge size swap and multi-caliber use in a single receiver for a versatile "do it all" rifle.
Following the original TL came the TL2 action, which featured an integral recoil lug, pinned scope rail, additional tang options, and a Remington 700 footprint for use in standard-inlet stocks and chassis.
Beginning as an evolution of the TL2, the TL3 action retains the ultra-repeatable, beautifully machined quality that shooters became accustomed to with the earlier TL and TL2 versions. In addition to this, the TL3 also comes with the added benefits of:
1. Controlled Feed
2. Mechanical Ejection
3. Pinned 20 MOA Picatinney Rail
4. Medium Tang
5. Competition Bolt Knob
6. Wider Ejection Port
7. Same Bighorn Arms Floating Bolt head capability of switching calibers
8. Bayonet Style Bolt Shroud for easy take down
9. AW Magazine Cut to run AICS or AW magazines.
10. DLC coated receiver.
