About Seekins Precision:

Seekins Precision has lived up to its name since the day it was born. The company was started as the result of a failed deer hunt in Idaho. The founder, Glen Seekins, was disenchanted with the fragility of the scope rings he used for the hunt. These rings broke during the course of the day, leading to a complete failure of the hunt. Glen came home and promptly designed stronger scope rings on his CAD program. Glen had a vision of designing and manufacturing high-quality parts and accessories for firearms. Eventually, he quit his job at the machine shop where he worked and began operating Seekins Precison full-time. He hasn’t looked back since.
