Offered for sale is a PTR Industries PTR-91 GI chambered in .308 Winchester / 7.62×51 NATO. The PTR-91 is an American-made semi-automatic rifle patterned after the legendary HK G3 and HK91 family of roller-delayed rifles.

PTR developed its Model 91 series using original HK-pattern specifications, tooling and manufacturing concepts, producing one of the best-known American versions of the classic G3-style rifle.

This particular example is configured in the traditional GI military style, complete with green furniture and the clean, rail-free receiver profile characteristic of the original G3 design.

Classic Roller-Delayed G3 Design

Unlike conventional gas-operated semi-automatic rifles, the PTR-91 utilizes the famous roller-delayed blowback operating system associated with the German G3 and HK91.

The rifle also incorporates the traditional fluted chamber, charging handle arrangement, hooded front sight and adjustable rotary rear drum sight that make the G3 family immediately recognizable.

Green Military-Style Furniture

This PTR-91 is equipped with distinctive green surplus-style furniture, including a fixed buttstock, pistol grip and ventilated slim-profile handguard.

The furniture displays visible handling, storage and service-style wear, including markings on the buttstock. These characteristics complement the rifle’s military G3 appearance.

The furniture has not been represented as original German HK manufacture unless separately verified by component markings.

PTR-91 GI and the G3 Heritage

The original G3 became one of the most recognizable military rifles of the Cold War era, with its roller-delayed operating system forming the basis for an entire family of HK firearms.

The PTR-91 GI recreates much of the appearance and mechanical character of that rifle in an American-manufactured semi-automatic configuration.

This example’s green military-style furniture, full-length barrel and traditional receiver configuration give it an especially authentic G3-inspired appearance compared with more modernized PTR configurations featuring rails and accessory furniture.
