You can't build a quality rifle without parts, so we've made it easy for you with the Seekins Precision Builders Kit. Our kit provides you with the integral parts needed to finish your lower receiver. Given the amount of personal preference that goes into choosing the perfect trigger, we have not included one in this kit. This kit features all of the Seekins Precision manufactured lower receiver parts as well as the pins and springs needed for assembly of your AR15 lower receiver. Builders kit sold as is and only available in black.
