Ptr Industries 9Ltr-Cs 9mm 16 Cs1 Stock 30Rd
The PTR Industries 9LTR-CS is a 9mm rifle built on a roller-delayed blowback system that delivers reliable, soft-shooting performance in a compact, maneuverable platform. Designed for shooters who want precision and durability without complexity, the 9LTR-CS pairs a 16-inch nitride heat-treated barrel with a rugged mil-spec aluminum handguard and a 4-position adjustable stock—making it equally at home at the range, in tactical training, or in a home-defense role. At 7.5 lbs and 33 inches overall, it balances stability with handling, and it ships ready to shoot with two 30-round magazines, a cable lock, and the CS1 stock already installed.
The heart of the 9LTR-CS is its 16-inch barrel, nitride hardened for durability and fitted with a 3-lug quick-change mount and 1/2 x 28 threading—perfect for mounting a suppressor or flash hider to dial in your setup. The roller-delayed blowback operation cycles cleanly and softly, reducing felt recoil and making follow-up shots fast and accurate. A full-auto bolt carrier with dead-blow weighting keeps things smooth, even during rapid strings.
Ergonomics matter, and PTR got them right: the 4-position CS1 stock lets you dial in length of pull for your body and gear, the mil-spec M-LOK aluminum handguard provides a stable platform for lights, lasers, or other accessories, and a Picatinny rail on top gives you room for your optic of choice. The 9-10 lb trigger is predictable and manageable. Finished in durable black powder coat over Parkerizing, the 9LTR-CS will handle heavy use and keep running.
