American-Made Upgrades by PTR

PTR supplies critical American-made components on the CA-3 to ensure reliability and parts availability: trunnion, barrel, flash hider, stamped receiver, hammer, sear and charging handle. These parts balance original surplus character with the practicality of modern manufacturing—important for maintainability and long-term service life.

Practical Use and Configuration

Presented in the Semi Auto category and priced at $935.99, the CA-3 comes with one 20-round magazine and is described as in Excellent condition despite expected signs of wear from service life. That wear contributes to its vintage appeal but does not affect core function when properly inspected and maintained. For buyers seeking a historically faithful G3 experience for the range or collection, this model hits the mark. View product details and pricing.
