OA 1911 Barrel – 9MM – Government – Non Ramp – Stainless

Oriskany Arms 1911 Barrel – 9mm Government | Non‑Ramped | Stainless Steel

Match‑Grade Performance with Reliable Drop‑In Convenience

The Oriskany Arms 9mm Government 1911 Barrel delivers precision, durability, and consistent accuracy for shooters who demand more from their pistols. Designed as a high‑quality drop‑in solution, this barrel combines modern CNC machining with traditional 1911 geometry. As a result, it offers improved lockup, smoother cycling, and dependable feeding right out of the box.

Precision CNC Machined in the USA

Each Oriskany Arms barrel starts as premium stainless‑steel bar stock and is CNC machined in the USA for maximum dimensional consistency. Moreover, the barrel features slightly oversized critical dimensions, which allows for a tighter, more repeatable lockup than typical factory barrels. Consequently, shooters benefit from enhanced mechanical accuracy and improved shot‑to‑shot consistency.

Heat Treated, Cryo Stress Relieved, and Built to Last

After machining, the barrel undergoes proper heat treatment followed by cryogenic stress relief. Therefore, internal stresses are reduced, dimensional stability is improved, and long‑term durability is increased. Over time, this process helps maintain accuracy while extending overall barrel life, even with high round counts.

Broach‑Cut Rifling for Superior Accuracy

Rather than using button or hammer forging, Oriskany Arms utilizes precision broach‑cut rifling. As a result, the rifling remains exceptionally uniform from chamber to muzzle. This design promotes excellent accuracy across a wide range of bullet profiles. Whether you run FMJ, JHP, or lead bullets, the barrel feeds smoothly and groups consistently.

Non‑Ramped Government Configuration

This barrel uses a traditional non‑ramped (frame‑ramped) design, making it ideal for standard Government‑length 1911 frames. Consequently, it integrates seamlessly into classic 1911 builds while preserving original feed‑ramp geometry. Additionally, the 5″ Government length provides a proven balance of reliability, velocity, and accuracy.

Included Barrel Bushing for Faster Installation

To simplify installation, each kit includes a matched barrel bushing. Therefore, many pistols can achieve proper fit more quickly compared to sourcing components separately. While designed as a drop‑in barrel, minor fitting may be required to achieve optimal performance, especially in tighter tolerance pistols.
