Kart Barrel – National Match Bull Barrel 9MM 5″ Non Ramped

Kart Barrel – Gunsmith Fit – National Match 9MM 5″ Bull Barrel – Non‑Ramped

The Kart Gunsmith Fit National Match 9MM 5″ Bull Barrel delivers elite, competition‑grade performance for shooters who demand maximum accuracy, reliability, and ballistic efficiency from their 1911. For decades, Kart has earned its reputation as one of the finest barrel manufacturers in the world. Accordingly, this model continues that legacy through meticulous machining, exceptional steel quality, and true match‑grade precision.

Engineered for Superior Accuracy

From the start, Kart forms each National Match barrel from high‑strength, ordnance‑grade steel forgings. Rather than relying on shortcuts or loose tolerances, Kart carefully cuts and rifles the bore using a proprietary process. As a result, the bore maintains extraordinary dimensional consistency while remaining exceptionally smooth.

Moreover, this mirror‑like bore surface reduces friction and stabilizes each projectile more effectively. Consequently, bullets track consistently through the barrel, which directly enhances accuracy and velocity uniformity.

In addition, Kart air‑gauges every barrel to an extremely strict .0002″ uniformity standard. Because of this, pressures remain consistent, velocities stay predictable, and shot‑to‑shot repeatability improves dramatically. Therefore, competitive shooters, custom 1911 builders, and professional armorers continue to choose Kart for top‑tier builds where accuracy matters most.

Stronger, Smoother Feeding Performance

In this configuration, the non‑ramped design uses the classic 1911 frame feed ramp. As a result, it works perfectly with standard GI‑style frames and traditional build layouts. At the same time, Kart refines the throat and feed geometry to enhance reliability.

Consequently, the barrel feeds a wide range of bullet profiles smoothly and consistently. Whether running hollow points, wadcutters, or defensive ammunition, shooters experience reliable chambering even during rapid fire. Thus, the barrel performs equally well in competition, training, and defensive roles.

Oversized for True Custom Fitment

Unlike drop‑in barrels, the Kart Gunsmith Fit National Match series intentionally uses oversized dimensions. This approach allows a skilled gunsmith to precisely cut and tune critical areas, including:

• Hood length

• Upper locking lugs

• Lower lug engagement

Through careful hand‑fitting, the barrel achieves ideal vertical engagement and perfect lockup. As a result, the slide and barrel return to battery with repeatable precision. Over time, this precision maintains tight tolerances, improves consistency, and preserves accuracy through thousands of rounds.

Ideal for Precision‑Focused 1911 Builds

Whether you are building a competition pistol, refining a defensive 1911, or upgrading a precision range gun, this barrel elevates the platform with Kart’s proven accuracy and reliability. Additionally, the non‑ramped design ensures compatibility with a wide range of traditional frames, making it an excellent choice for classic and modern builds alike.
