Kart Barrel – XACT Fit Kit – 45ACP 5″ Clark / Para Ramped

Kart Barrel – XACT Fit Kit – .45 ACP

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

Match-Grade Accuracy Without Extensive Gunsmith 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 while, at the same time, want to avoid the cost, time, and complexity associated with traditional gunsmith-fit barrels. For that reason, Kart developed 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 design and manufacturing expertise. In addition, this model features a 5″ Government-length, Clark/Para ramped .45 ACP barrel, 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 designed as a semi-drop-in match barrel. As a result, it effectively 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 advanced manufacturing approach, each barrel consistently delivers:

• A mirror-smooth bore, which improves bullet travel

• Uniform bullet stabilization, thereby enhancing accuracy

• Reduced friction, which supports efficiency and longevity

• Improved long-range precision, especially under competition conditions

Additionally, Kart air-gauges each bore to a strict .0002″ tolerance. Consequently, pressures remain consistent from shot to shot, which, in turn, ensures reliable and repeatable accuracy.

Clark/Para Ramped Design for Superior Case Support

This version incorporates a Clark/Para ramped barrel design, which significantly improves chamber support and overall feeding reliability. As a result, the barrel performs exceptionally well in both competition and duty environments.

Specifically, this design provides:

• Enhanced case-head support for higher-pressure loads

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

• More consistent ignition and chamber alignment

• Increased durability compared to standard non-ramped barrels

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

Faster Installation with Gunsmith-Level Results

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

As a result, this system is particularly well suited 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 excessive labor

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