Frequently Asked Questions
What ammunition has this kit been tested with?
Our staff has installed this kit in multiple builds. It runs reliably with standard 115gr and 124gr FMJ range ammunition. We did experience one failure to feed with a specific brand of 147gr subsonic rounds during testing, which was likely ammunition-specific. For defensive or heavy subsonic loads, ensure proper break-in and testing.
Is this a complete lower parts kit?
Yes, this Accessories – Fast Ship kit contains all the necessary internal components to complete a Polymer80 frame, excluding the slide, barrel, and magazine. It includes the lower parts kit (LPK) along with other standard internal parts required for assembly.
Do I need any gunsmithing experience to install this?
Basic mechanical aptitude and the proper tools are required. Installation involves driving pins and assembling small components. We recommend following a detailed build guide or video tutorial specific to the Polymer80 platform. Patience during the fitting process is key to a smooth-functioning final product.
