The Thompson Center Arms 3170R Encore buttstock with thumbhole design is a factory-direct replacement component engineered for shooters who want a customizable platform. If you run a Thompson Center ProHunter rifle and need to swap out the buttstock—whether you're chasing precision at the range, hunting across changing seasons, or simply refining your rifle's ergonomics—this polymer thumbhole stock delivers a purpose-built grip configuration and a factory fit you can rely on.
Thompson Center's buttstock and forend ecosystem is built on the principle of quick, tool-free modularity. This thumbhole buttstock swaps in without gunsmithing, giving you the ability to tune your rifle's handling and comfort to your specific shooting style. The thumbhole design provides a secure, high-grip position that many shooters prefer for stability and control, particularly when working from bench or prone positions. Constructed from durable polymer, it's designed to withstand field use while keeping weight down.
Whether you're a dedicated ProHunter operator looking to maximize your platform or a shooter who values the flexibility to reconfigure your rifle for different roles, this buttstock is a genuine OEM part that fits exactly as Thompson Center intended. Black polymer construction resists weathering, and the thumbhole geometry encourages a consistent, repeatable shooting grip that translates into better shot placement.
