Description:
First released in November 2019, the GST-9 V1 set a precedent for the 80% frame market. It provided a modular grip system while maintaining Gen 3 G19 parts compatibility. With 3 years of customer feedback and thousands of rounds down range, we’ve raised the bar again with the new GST-9 MOD1 frame!
The gas pedal shape and location were revised and re-contoured for optimized controls during the recoil cycle. The grip system was redesigned to guarantee a flush fit with grip modules when building out your frame. Last but not least, the rear rails were split into a 2-piece system to greatly help streamline the assembly process.

Regulatory Information:
Due to ATF regulations, we cannot legally include the jig or frame rails with the MOD1 frame. The jig and MOD1 frame must be purchased on our website as two separate items. Each jig includes one set of MOD1 frame rails. You will need to purchase one jig for every MOD1 frame you plan to build. Frame rails are ONLY included with the jig, not with the 80% lower itself.
