PTR Industries, based in Aynor, South Carolina, specializes in roller-delayed blowback firearms in the tradition of the Heckler & Koch G3 and its variants. Using tooling and designs descended from the original pattern, PTR builds American-made rifles and pistols that recreate the robust, battle-proven roller-delayed system for U.S. shooters.
The lineup spans the classic .308 G3/HK91-pattern rifles (the PTR-91 family), 5.56 variants, the 7.62×39 PTR-32, and the 9mm PTR-9 — the latter echoing the MP5 platform. These guns are prized by enthusiasts of the roller-delayed action for their distinctive shooting characteristics, durability, and the heritage they carry.
For shooters who appreciate the roller-delayed HK pattern and want an American-made example, PTR Industries is the leading specialist in the category.
