Common Questions
Does this kit include a pistol grip and stock?
No, the Patriot Pack includes all internal lower parts and the buffer tube assembly (tube, buffer, spring). You will need to separately purchase your chosen pistol grip and stock (or brace) to complete the external lower assembly.
Is the trigger a standard mil-spec single-stage?
Yes. This kit includes a standard mil-spec single-stage trigger group. It provides a reliable, consistent pull suitable for most builds and is an ideal foundation for your project.
Are the small springs and detents easy to manage during installation?
The parts are bagged separately by function (e.g., fire control group, safety selector). We recommend using a dedicated lower receiver vise block and a set of roll pin punches to make installation straightforward and to prevent launching any small springs.
