Oriskany Arms 1911 Frame – 5″ Government – Tactical – Carbon Steel – Standard Ramp

Build a Strong, Reliable 1911 Foundation

Oriskany Arms delivers builders a durable, American-made 1911 frame that supports premium builds. Moreover, this 5″ Government frame offers features typically found on higher-priced models. Consequently, it works perfectly for both defensive pistols and competition-ready builds. Furthermore, it provides an ideal platform for custom gunsmithing, giving shooters flexibility and confidence.

Precision Materials for Long-Term Performance

In addition, Oriskany Arms machines each frame from tough 4140 carbon steel, ensuring exceptional strength and longevity. First, the company precision-casts the frame, and then it CNC-machines all critical surfaces to exact dimensions. As a result, gunsmiths receive a true-to-spec platform that fits consistently and responds exceptionally well to custom tuning and finishing. Therefore, you gain both reliability and versatility in one frame.

Why Builders Choose the Oriskany Arms 1911 Frame

Precision 4140 Carbon Steel Construction

The frame begins as a 4140 carbon steel casting. Then, Oriskany Arms CNC-machines it to create a rugged platform that endures heavy use while maintaining clean, consistent dimensions. Consequently, shooters benefit from a frame that performs consistently under stress.

Oversize Rails for Tight Slide Fit

The oversize frame rails allow gunsmiths to hand-fit the slide for a smooth, precise action. As a result, the completed 1911 delivers improved accuracy and more consistent cycling. Additionally, this tight fit enhances reliability during rapid-fire sequences and increases overall performance under demanding conditions.

20 LPI Checkered Front Strap

Oriskany Arms adds 20 lines-per-inch checkering to the front strap. This pattern provides secure traction without feeling harsh. Furthermore, it improves control during fast strings of fire, while remaining comfortable for long shooting sessions. Consequently, shooters gain both style and functionality in every grip.

Heat-Treated for Durability and Machinability

After machining, Oriskany Arms heat-treats the frame to Rc 22–24. Therefore, the frame balances strength with ease of customization. As a result, gunsmiths can modify or tune the frame efficiently, while shooters enjoy long-term durability. Additionally, this process ensures that the frame maintains its precision, even after extensive use.

Trusted American Firearms Manufacturer

Oriskany Arms has produced precision firearm components since 1947. Moreover, in 2013, the company expanded its lineup to include American-made Series 1911 pistols in .45 ACP and 9mm. Consequently, every frame reflects decades of engineering expertise and machining experience. Therefore, shooters can trust in the quality, performance, and legacy of each frame.
