SPIKES UPPER/LOWER SET STSB920

The SPIKES UPPER/LOWER SET STSB920 offers a precision-engineered platform designed to enhance the performance and durability of your build. Manufactured by SPIKES, this set features a lightweight lower receiver with machined pockets that strategically reduce weight without compromising strength. The design incorporates 3D chamfered edges and surfaces to minimize snagging, ensuring smoother handling and operation.
