The PROOF ASCENSION 300PRC 22 9 5/8-24 TFDE 141458 is a high-end, mountain-ready bolt-action rifle built for hunters and precision shooters who expect custom-rifle performance in a turn-key package. Chambered in .300 PRC and built around PROOF’s patented carbon fiber–wrapped barrel, a titanium Zermatt receiver, and a TFDE Monte Carlo carbon fiber stock, this rifle delivers long-range precision, low weight, and rugged durability for serious backcountry work.
Purpose-Built for Long-Range .300 PRC Performance
The Ascension in .300 PRC is designed from the ground up for modern long-range hunting and precision shooting:
Caliber: .300 PRC – optimized for high-BC, heavy bullets that hold velocity and buck the wind at extended ranges.
Ideal for western big-game hunting, cross-canyon shots, and long-range steel where ballistic consistency matters.
Bolt action, right-hand configuration with a smooth cycling stroke and hunting-friendly layout.
If your hunting and shooting stretch beyond typical “point and shoot” distances, the Ascension 300 PRC provides the horsepower and precision to do it responsibly.
22" PROOF Carbon Fiber–Wrapped Sendero Barrel – 1:9 Twist, 5/8x24
Accuracy and weight savings start at the muzzle, and PROOF’s barrels are the centerpiece of the platform:
22" PROOF patented carbon fiber–wrapped, match-grade barrel in Sendero contour, combining a stainless match core with an advanced carbon wrap for stiffness at reduced weight.
1:9" twist rate, specifically chosen for stabilizing the long, heavy .30-cal projectiles favored in .300 PRC for long-range and hunting applications.
5/8x24 threaded muzzle comes with a thread protector installed from the factory, ready for your preferred brake or suppressor.
PROOF’s carbon barrels are known for excellent rigidity and heat dissipation, helping maintain consistent point of impact from cold-bore to follow-up shots—critical for a first-round hit in the field.
Titanium Zermatt Receiver – Strong, Light, and Precise
The Ascension platform is built on a titanium receiver from Zermatt Arms, giving you true custom-action quality in a factory rifle:
Lightweight titanium action provides excellent strength and corrosion resistance while shaving weight compared to traditional steel receivers.
Finished in black Cerakote, the action is well-protected against harsh weather and hard hunting conditions.
PROOF’s extreme-accuracy bedding system mates the action precisely to the stock, promoting repeatable lock-up and tight groups across temperature and elevation swings.
This titanium core is a big part of how the Ascension delivers both featherweight carry and serious precision.
TFDE Monte Carlo Carbon Fiber Ascension Stock
The Ascension stock takes a classic Monte Carlo silhouette and updates it with modern materials and ergonomics:
Carbon fiber Monte Carlo stock, purpose-built for the Ascension line, offers an outstanding strength-to-weight ratio that resists warping or swelling in wet or cold conditions.
Higher comb and refined grip geometry deliver a comfortable, repeatable cheek weld and natural trigger reach—perfect for today’s larger, higher-mounted optics.
Finished in TFDE (Tactical Flat Dark Earth), giving the rifle a modern, earth-tone look that blends into real backcountry terrain and pairs nicely with black Cerakote metal.
This stock isn’t just about looks; it’s designed to shoulder quickly and feel right from prone, kneeling, or awkward mountain shooting positions.
Sub 1/2 MOA Accuracy Guarantee
The Ascension series is built and tested to a very high standard:
PROOF backs the platform with a SUB ½ MOA accuracy guarantee, meaning the rifle is tested to shoot under 0.5 MOA (three-shot groups at 100 yards) with quality ammunition and a capable shooter.
Every rifle is test-fired at the factory to confirm this level of performance before it ships.
You’re not just buying a lightweight hunting rifle; you’re buying a precision instrument that’s ready for serious long-range work.
TriggerTech Trigger & Extreme-Accuracy Bedding
To make use of the rifle’s inherent precision, PROOF loads the Ascension with top-tier components:
Equipped with a TriggerTech trigger, known for its crisp, zero-creep break and minimal over-travel, helping you call shots cleanly even in steep-angle or improvised field positions.
Extreme-accuracy bedding system ensures the titanium action is locked into the carbon stock for consistent harmonics and point-of-impact stability.
This combination makes the rifle especially forgiving when you’re tired, winded, and trying to break a clean shot in the wind.
3+1 Capacity, BDL-Style Internal Magazine
The PROOF Ascension 300 PRC 141458 is configured as a field-ready hunting rifle:
Capacity: 3+1 in .300 PRC – three rounds in the internal magazine plus one in the chamber.
BDL-style internal magazine keeps the bottom of the rifle sleek and snag-free—ideal for scabbards, saddle carry, slings, and tight pack straps.
You get plenty of rounds on board for real-world hunting scenarios without the bulk or noise of a protruding detachable mag.
Lightweight, Mountain-Ready Design
Despite the magnum chambering and match-level precision, the Ascension keeps weight in true mountain-rifle territory:
The Ascension line is designed to fall roughly in the 5 lb 5 oz – 6 lb 4 oz range depending on configuration; this 22" 300 PRC TFDE build sits near the top end of that, still very light for a magnum-capable, long-range rifle.
22" barrel length keeps the rifle more compact in thick timber, blind windows, and tight rock outcrops while still delivering excellent .300 PRC performance—especially when paired with modern powders and bullets.
Once you add a lightweight scope and rings, you end up with a full-size, magnum long-range rig that you can realistically carry all day in steep, high-country terrain.
For hunters who count ounces and still demand top-tier accuracy, that blend is a big deal.
