The PROOF ASCENSION 300WM 22 10 5/8-24 TFDE 141359 843068141359 is a premium, mountain-ready bolt-action rifle built for serious long-range hunters who want custom-rifle performance in a turn-key package. Chambered in .300 Winchester Magnum, this Ascension features PROOF’s 22" patented carbon fiber–wrapped match-grade barrel, a titanium receiver from Zermatt Arms, and a carbon fiber Monte Carlo Ascension stock in Tactical Flat Dark Earth (TFDE), all backed by a sub 1/2 MOA accuracy guarantee.
Built for Long-Range, High-Country Hunting
The Ascension 300 Win Mag is designed for hunters and shooters who live in steep, big country and demand reliable performance at extended ranges:
Caliber: .300 Win Mag – a proven long-range hunting cartridge with excellent downrange energy and trajectory for elk, mule deer, and other large game.
Role: High-country hunting and precision field shooting where shots may come cross-canyon or in high winds.
Action: Right-hand bolt action with smooth cycling and a hunting-friendly safety layout.
If you’re packing into remote basins or glassing huge ridges, this rifle is built to be light enough to carry all day and accurate enough to capitalize on those hard-earned opportunities.
22" PROOF Carbon Fiber–Wrapped Sendero Barrel – 1:10 Twist, 5/8-24
PROOF barrels are the heart of their rifles, and this Ascension carries that reputation forward:
Barrel Length: 22" Sendero contour carbon fiber–wrapped match-grade barrel.
Patented carbon fiber wrap over a stainless match core gives you the stiffness of a much heavier steel barrel at a fraction of the weight, with excellent heat management.
Twist Rate: 1:10 – ideal for stabilizing a wide range of .300 Win Mag hunting and long-range bullets.
Muzzle: Threaded 5/8x24 with a thread protector installed from the factory, ready for brakes or suppressors.
The Sendero contour balances beautifully on a hunting rifle—stout enough to stay consistent as the barrel heats, but still light enough to carry miles into the backcountry.
Titanium Receiver from Zermatt Arms – Strong, Light, Precise
The Ascension series is built on a titanium receiver from Zermatt Arms, giving it a truly custom-grade core:
Titanium action delivers outstanding strength and corrosion resistance while shaving significant weight compared to all-steel receivers.
Precision machining and PROOF’s extreme-accuracy bedding system ensure a tight interface with the stock and repeatable lock-up shot after shot.
Typically finished in black Cerakote, the receiver is built to shrug off harsh weather, hard use, and rough rides on pack frames.
This combination of titanium and carbon fiber materials is what lets the Ascension offer custom-rifle performance while still coming in at mountain-rifle weights.
Ascension TFDE Monte Carlo Carbon Fiber Stock
The Ascension stock is PROOF’s modern take on a classic Monte Carlo hunting stock:
Carbon fiber Monte Carlo stock designed specifically for the Ascension platform, tuned for ergonomics and aesthetics.
Higher comb and refined grip geometry provide a natural, repeatable cheek weld and comfortable trigger reach, especially with today’s larger optics.
Finished in TFDE (Tactical Flat Dark Earth)—a modern earth-tone that blends into real-world terrain and pairs nicely with black barrels, receivers, and optics.
Carbon fiber construction offers an excellent strength-to-weight ratio and resists warping or swelling in wet, cold, or hot conditions.
From prone on a ridge to kneeling behind a log, this stock is built to feel natural and stay consistent in real hunting positions.
TriggerTech Trigger & Extreme-Accuracy Bedding
Shootability is where details matter, and PROOF loads the Ascension with top-tier components:
Equipped with a TriggerTech trigger, known for a crisp, zero-creep break and minimal over-travel, helping you call shots cleanly at distance.
PROOF’s precision extreme-accuracy bedding system ensures the action is mated solidly to the stock for stable harmonics, consistent cold-bore shots, and reliable point of impact across temperature swings.
When you’re winded from the climb and your shot window is short, a clean trigger and confidence in your bedding system make a real difference.
Sub 1/2 MOA Accuracy Guarantee
The Ascension isn’t just light and pretty—it’s built to shoot:
Backed by PROOF’s sub 1/2 MOA accuracy guarantee, meaning the rifle is tested and proven capable of under 0.5 MOA (3-shot groups at 100 yards) with quality ammo and a capable shooter.
Every rifle is rigorously test-fired before it leaves the factory, with results documented to validate that guarantee.
That level of precision is rare in a rifle built to live in the mountains, and it’s a big reason serious hunters gravitate toward PROOF rifles.
BDL-Style Internal Magazine – 3+1 Capacity
The PROOF Ascension 300WM 141359 is configured as a traditional, field-ready hunting rifle:
BDL-style internal magazine setup keeps the bottom of the rifle slim and snag-free for hand carry, saddle scabbards, or pack straps.
Capacity: 3+1 in .300 Win Mag – three in the magazine plus one in the chamber, plenty for real-world hunting scenarios.
No exposed detachable magazine to lose or damage in rough terrain.
It’s a classic, proven configuration that prioritizes reliability and practicality in the field.
Threaded Muzzle – Ready for Brakes or Suppressors
Modern hunters increasingly want the option to tame recoil or run suppressed, and the Ascension is ready out of the box:
5/8x24 threaded muzzle is compatible with a wide range of muzzle brakes, suppressor mounts, and direct-thread silencers.
Ships with a thread protector installed, so you can run the rifle “bare” until you’re ready to add a device.
On a lightweight .300 Win Mag, adding a brake or can can make the rifle significantly more pleasant to shoot during long range sessions or when practicing from field positions.
Lightweight, Mountain-Ready Design
Despite packing a magnum cartridge and match-grade accuracy, the Ascension is impressively light and handy:
Built with a carbon barrel, carbon stock, and titanium receiver to keep weight in a true mountain rifle class.
Typical Ascension rifles fall in the ~6 lb range bare (exact weight depends on configuration), making them ideal for all-day carry in vertical country.
22" barrel length keeps the rifle compact and maneuverable in timber, on steep side-hills, and in tight blinds, while still offering the performance you expect from .300 Win Mag.
Add a light optic and rings, and you’ll still have a rig you won’t dread hauling up the mountain.
