OA 1911 Frame – CDR – Tactical – Carbon Steel Standard Ramp

Oriskany Arms 1911 Frame – 4.25″ Commander – Tactical – Carbon Steel – Standard Ramp

Strong, Reliable, American-Made Foundation

Oriskany Arms provides builders a durable, reliable, and American-made foundation for premium 1911 pistols. Moreover, this 4.25-inch Commander 1911 frame delivers exceptional value. In addition, it includes features often found on frames costing two to three times as much. Therefore, shooters can confidently use it for defensive, competition, or custom builds.

Precision Materials for Long-Term Performance

Furthermore, Oriskany Arms machines each frame from 4140 carbon steel, ensuring strength and long service life. They precision-cast the frame, then CNC-machine it to exact final dimensions. Consequently, gunsmiths receive a consistent, true-to-spec platform that responds well to fitting, tuning, and finishing.

Why the Oriskany Arms 1911 Frame Stands Out

Precision 4140 Carbon Steel Construction

The frame begins as a 4140 carbon steel casting, and Oriskany Arms machines it with CNC accuracy. This process creates a rugged platform that handles heavy use while maintaining clean, consistent dimensions.

Oversize Rails for a Tight Slide-to-Frame Fit

Additionally, the oversized rails allow gunsmiths to hand-fit the slide for a tight, smooth action. As a result, the finished 1911 often achieves noticeably better accuracy and more consistent cycling.

20 LPI Checkered Front Strap for Enhanced Grip

Moreover, Oriskany Arms adds 20 lines-per-inch checkering to the front strap. This pattern provides secure traction without feeling aggressive. In turn, shooters gain improved control during fast strings of fire while maintaining comfort during extended use.

Heat-Treated for Strength and Machinability

After machining, Oriskany Arms heat-treats each frame to Rc 22–24. Therefore, the frame balances durability with ease of customization. Consequently, it withstands long-term use while remaining easy to modify or tune.

Backed by Decades of American Firearm Expertise

Oriskany Arms has produced precision firearm components since 1947. In 2013, the company expanded its lineup to include a full line of American-made Series 1911 pistols in .45 ACP and 9mm. Hence, every frame reflects decades of machining experience and proven firearm engineering.
