5″ Government 1911 Frame – Tactical Carbon Steel (Clark/Para Ramp)
A Strong Foundation for Premium 1911 Builds
The Oriskany Arms 5″ Government 1911 Frame delivers a strong, reliable, and American-made foundation for serious 1911 builds. Moreover, this tactical Government-length frame offers exceptional value because it includes features often found on frames that cost significantly more. As a result, builders confidently choose it for defensive pistols, competition guns, and high-end custom projects alike.
Precision Materials for Long-Term Performance
Additionally, Oriskany Arms machines every frame from durable 4140 carbon steel to ensure strength and long service life. First, the company precision-casts each frame. Then, it CNC-machines every critical surface to exact final dimensions. Because of this process, gunsmiths receive a true-to-spec platform that fits consistently and responds predictably to tuning and custom work.
Why the Oriskany Arms 1911 Frame Excels
Precision 4140 Carbon Steel Construction
To begin with, Oriskany Arms starts with quality 4140 carbon steel and machines it with CNC accuracy. Consequently, the frame delivers a rugged structure that handles hard use while maintaining clean, consistent dimensions throughout.
Oversize Rails for a Tight Slide Fit
Next, the oversize frame rails allow gunsmiths to hand-fit the slide for a tight, smooth action. Therefore, builders achieve improved accuracy and more consistent cycling once the pistol reaches final assembly. In turn, this tight fit enhances overall performance and control.
20 LPI Checkered Front Strap
At the same time, the frame features 20 line-per-inch checkering on the front strap. This pattern adds grip without feeling overly aggressive. Furthermore, it improves control during rapid strings of fire while remaining comfortable during extended shooting sessions.
Heat Treatment for Strength and Machinability
After machining, Oriskany Arms heat-treats each frame to Rc 22–24. As a result, the frame balances durability with machinability. Consequently, gunsmiths can perform custom work efficiently while shooters benefit from long-term reliability.
Backed by Decades of American Manufacturing
Importantly, Oriskany Arms has produced precision firearm components since 1947. Later, in 2013, the company expanded its lineup to include American-made Series 1911 pistols in .45 ACP and 9mm. Therefore, every frame reflects decades of machining experience and proven firearm engineering.
