Kart Barrel – National Match 400 COR-BON 5″ Barrel – Non-Ramped

The Kart Barrel – National Match 400 COR-BON 5″ Barrel – Non-Ramped delivers elite, competition-grade performance for shooters who demand maximum accuracy, reliability, and ballistic efficiency from their 1911. Kart has earned a reputation as one of the finest barrel manufacturers in the world, and this model continues that legacy with meticulous machining, exceptional steel quality, and true match-grade precision.

Engineered for Superior Accuracy

Kart starts each National Match barrel with high-strength ordnance-grade forgings. Instead of relying on shortcuts or loose tolerance machining, Kart cuts and rifled the bore using its proprietary process, which maintains extraordinary dimensional consistency. As a result, the bore surface remains mirror-smooth, reduces friction, and stabilizes each projectile more effectively.

Furthermore, every barrel is air-gauged to an incredibly strict .0002″ uniformity standard. This level of precision ensures consistent pressures, predictable velocity, and exceptional shot-to-shot repeatability. Because of this, competitive shooters, custom 1911 builders, and professional armorers routinely choose Kart for top-tier builds.

Stronger, Smoother Feeding Performance

This non-ramped version uses the classic 1911 frame feed ramp, which makes it ideal for shooters running standard GI-style frames. Kart enhances the throat and feed-ramp geometry to support smooth cycling with a wide range of bullet profiles. Consequently, hollow points, wadcutters, and defensive loads feed with greater reliability, even under fast-paced shooting conditions.

Oversized for True Custom Fitment

Unlike drop-in barrels, the Kart National Match series is intentionally oversized. This design allows a skilled gunsmith to cut and tune the:

• Hood length

• Upper locking lugs

• Lower lug engagement

Through proper hand-fitting, the barrel achieves perfect lockup and optimal vertical engagement. As a result, the slide and barrel return to battery with repeatable precision, dramatically improving accuracy and maintaining tight tolerances through thousands of rounds.

Built for 400 COR-BON Performance

The 400 COR-BON cartridge generates high velocities and significant pressure, especially compared to standard .45 ACP loads. Because of this, Kart strengthens the barrel’s construction and maintains robust chamber support. This results in excellent durability, reliable cycling, and consistent ballistic performance—even when firing high-pressure defensive or hunting loads.

Ideal for Precision-Focused 1911 Builds

Whether you are building a competitive pistol, tuning a defensive 1911, or upgrading a hunting sidearm, this barrel elevates your platform with Kart’s renowned precision and reliability. Additionally, the non-ramped design makes it compatible with a broader range of classic frames.
