Originally released in November 2019, the GST-9 V1 was 80 Percent Arms’ answer to the 80% polymer frame market. It served as the first polymer frame to feature a modular grip design without losing part compatibility. Even with the inclusion of the newer GST-9 MOD1, it still provides users with one of the most functional and customizable frames on the market.

Curious about the GST9 platform? Apprehensive about your first build? Check out our blog that discusses the differences! Rest assured that the V1 gives you the same controls and ergonomics of the MOD1 frame for budget friendly builds.
