Kart Barrel – XACT Fit Kit – 40S&W 5″ C/P Ramped Bull Barrel

Kart Barrel – Xact Fit Kit – 40S&W 5″ Government Clark/Para Ramped Bull Barrel | Match-Grade 1911 Barrel Upgrade

Kart Barrel Xact Fit Kit — Match-Grade Accuracy Made Simple

The Kart Barrel Xact Fit Kit delivers true match-grade performance without the time, cost, or complexity of a full custom barrel installation. From the start, Kart designed this system for shooters, gunsmiths, and competitive 1911 builders who demand precision with efficiency. As a result, you gain exceptional accuracy, rock-solid lockup, and proven reliability—faster and with far less effort.

Why the Xact Fit System Stands Apart

Unlike ordinary drop-in barrels, the Kart Xact Fit Kit uses a semi-drop-in, precision-controlled design. Because of this, shooters achieve the accuracy benefits of a traditional gunsmith-fit Kart barrel while making only minimal, straightforward adjustments. At the same time, Kart preserves the tight tolerances required for serious competitive use.

Match-Grade Accuracy With Minimal Fitting

First and foremost, Kart machines every Xact Fit barrel from premium ordnance-grade steel. In addition, Kart applies a proprietary rifling process that maximizes consistency from shot to shot. Moreover, each bore is air-gauged to an ultra-tight .0002″ tolerance, ensuring uniform pressures and predictable accuracy.

What This Means for the Shooter

• As a result, the mirror-smooth bore reduces friction

• Consequently, bullets stabilize more consistently

• Therefore, velocity remains more uniform

• Ultimately, precision improves at extended distances

Because of these refinements, shooters experience tighter groups, increased confidence, and repeatable performance under match conditions.

Optimized Feeding Geometry for Proven Reliability

Over decades of development, Kart has perfected feed ramp geometry across GI, Clark/Para, and Wilson/Nowlin ramp styles. As a result, cartridges transition smoothly from magazine to chamber with consistent alignment. Meanwhile, Kart refines the throat and feed path to control cartridge entry and maintain reliable chambering.

Consequently, the barrel feeds a wide range of bullet profiles with ease. Whether firing wadcutters, hollow points, or modern defensive ammunition, feeding remains smooth and predictable. Even during rapid fire, reliability remains unchanged. Ultimately, this refined geometry supports competition, training, and defensive use alike.

Faster Installation With Professional Results

Rather than requiring extensive hand fitting, the Xact Fit system incorporates pre-machined fitting pads and controlled dimensions. Because of this, installation time is dramatically reduced. While proper fitting is still required—typically hood length and lower lug engagement—the process is faster, simpler, and more repeatable than fitting a traditional National Match barrel.

Ideal Applications

• For example, custom 1911 builds

• Likewise, accuracy upgrades for factory pistols

• Additionally, USPSA, IPSC, and IDPA competition guns

• Especially, gunsmiths seeking efficient, repeatable fitment

• Finally, enthusiasts pursuing true match-grade precision

Built for Accuracy, Consistency, and Longevity

Beyond initial accuracy, every Kart Xact Fit barrel is engineered for long-term performance. Because of superior materials, precision machining, and refined geometry, lockup remains tight over high round counts. Therefore, accuracy stays consistent match after match. In the long run, this durability protects both performance and investment.

What’s Included

To ensure proper installation, the kit includes:

• Kart Xact Fit barrel
