Kart Barrel XACT Fit Kit – 45ACP 5″ C/P Ramped Bull Barrel

Kart Barrel – XACT Fit Kit – .45 ACP

5″ Government Clark/Para Ramped Bull Barrel | Match-Grade 1911 Upgrade

Match-Grade Accuracy Without the Complexity of Full Custom Fitting

The Kart Barrel XACT Fit Kit .45 ACP Barrel is specifically engineered for shooters, gunsmiths, and competitive 1911 builders who demand match-grade accuracy yet, at the same time, want to avoid the cost, time, and complexity of a traditional gunsmith-fit barrel. For that reason, Kart designed the XACT Fit system to deliver exceptional lockup, superior accuracy, and reliable feeding while, importantly, reducing installation time.

Moreover, because Kart is one of the most respected names in precision 1911 components, this barrel reflects decades of proven engineering. In addition, this model features a 5″ Government-length, Clark/Para ramped bull barrel in .45 ACP, which, as a result, provides outstanding case support, increased durability, and consistent performance in demanding applications.

Match-Grade Accuracy with Minimal Fitting

Unlike standard drop-in barrels, the Kart XACT Fit Kit is engineered as a semi-drop-in match barrel. As a result, it perfectly bridges the gap between convenience and precision. Rather than sacrificing accuracy for ease of installation, you gain the performance of a fully fitted Kart barrel while still requiring only minimal adjustment.

Furthermore, Kart machines every barrel from premium ordnance-grade steel and applies a proprietary rifling process. Because of this, each barrel consistently delivers:

• A mirror-smooth bore, which improves bullet travel

• Consistent bullet stabilization, thereby enhancing accuracy

• Reduced friction, which supports velocity and barrel life

• Enhanced long-range precision, especially in competition use

Additionally, Kart air-gauges each bore to an ultra-tight .0002″ tolerance. Consequently, uniform pressures are maintained from shot to shot, which, in turn, ensures reliable and repeatable accuracy.

Clark/Para Ramped Bull Barrel for Superior Case Support

This version incorporates a Clark/Para ramped bull barrel design, which significantly improves chamber support and overall durability. As a result, the barrel performs exceptionally well under high round counts and demanding firing schedules.

Specifically, this design offers:

• Enhanced case-head support for higher-pressure loads

• Improved feeding reliability with hollow points, FMJ, defensive, and competition ammunition

• More consistent ignition due to better chamber alignment

• Increased durability when compared to standard non-ramped barrels

Therefore, whether you are building a competition pistol or upgrading a duty firearm, this barrel provides the reliability and strength required for serious use.

Faster Installation with True Gunsmith-Level Results

The Kart XACT Fit Kit includes precision pre-machined components that dramatically streamline the installation process. While some fitting is still required—most commonly hood length and lower lug adjustments—the process is far quicker and more predictable than fitting a traditional National Match barrel.

As a result, this system is ideal for:

• Custom 1911 builds

• Accuracy upgrades for factory pistols

• USPSA, IPSC, and IDPA competition firearms

• Gunsmiths seeking time-efficient, repeatable fitment

• Enthusiasts who want match-grade precision without excess labor

Consequently, you achieve professional-level performance while saving valuable time.
