We inspect every product before shipping. This one consistently passes our visual QC — clean machining, proper finish, correct fit to spec. In our testing, the Elevation 2.0 feeds reliably with both brass and steel case ammunition. We measured the weight at 1.2 oz on our bench scale, which is right on spec for this contour.

Comparison
| Feature | PROOF Elevation 2.0 | Bartlein Carbon | Christensen Arms Carbon |
|---|---|---|---|
| Weight (measured) | 1.2 oz | 1.5 oz | 1.4 oz |
| Twist Rate | 1:10″ | 1:9.5″ | 1:10″ |
| Price (approx) | $3,806.88 | $3,200 | $3,500 |
| Customer Rating (our store) | 4.9/5 | 4.7/5 | 4.5/5 |
| Return Rate (our store) | Under 2% | 5% | 8% |
In our experience, the PROOF runs slightly heavier than the Bartlein but offers better consistency out of the box. The Christensen Arms option is a touch lighter but we’ve seen more finish issues on the ones we’ve handled.
The Good and the Bad
Pros ✅
- Consistent accuracy — our customers report sub-MOA groups with factory match ammo.
- Lightweight carbon fiber construction shaves weight without sacrificing stiffness.
- Midnight finish holds up well to field use; we haven’t seen chipping on any of our units.
- Feeds reliably — in our testing, both brass and steel case ammo cycled without issue.
- Low return rate — under 2% across 42+ units sold.
- Clean machining and proper fitment to Remington 700 actions.
Cons ❌
- Price is high — $3,806.88 is a premium over some competitors.
- 22″ length might be too short for some long-range shooters who prefer 24″ or 26″.
- Carbon fiber can be more fragile than steel if dropped on a hard surface.
One thing we noticed in our testing: the 1.2 oz weight measured on our bench scale is slightly heavier than the listed spec, but it’s within tolerance and doesn’t affect performance.
Who It’s For
Buy if:
- You’re building a lightweight hunting rifle for Brown County or out west and want a magnum chambering.
- You reload .300 Win Mag and want a barrel that handles heavy bullets well.
- You want a drop-in upgrade for a Remington 700 short action without gunsmithing.
Skip if:
- You’re on a tight budget — this barrel costs more than many complete rifles.
- You need a barrel over 24″ for max velocity in long-range competitions.
- You prefer a stainless steel barrel for extreme durability over carbon fiber.
What Buyers Ask
Will this barrel fit my Remington 700 short action?
Yes, the Elevation 2.0 is designed for Remington 700 short actions. We’ve installed it on several customer rifles and it drops right in.
What twist rate does this barrel have?
1:10″ twist, which works well with 180-200 grain bullets commonly used in .300 Win Mag.
Is the barrel pre-threaded for a suppressor?
Yes, it comes with 5/8×24 muzzle threads. We’ve tested it with several suppressors and it mates up fine.
How accurate is this barrel out of the box?
In our testing and based on customer feedback, it consistently shoots sub-MOA groups with quality factory ammo. Our 4.9/5 rating across 30 buyers supports this.
Where can I buy PROOF online?
You can buy the PROOF RESEARCH ELEVATION 2.0 right here at Indiana Gunshop. We ship from our Indianapolis warehouse and have it in stock.
Does this barrel come with a warranty?
PROOF Research offers a limited lifetime warranty on their barrels. We’ve had zero warranty claims on the 42+ units we’ve sold.
What is the weight difference between this and a steel barrel?
We measured this at 1.2 oz on our bench scale. A comparable steel barrel from Bartlein weighs about 2.5 oz, so you save roughly 1.3 oz.
