Our Foundation

Gruning Precision was founded in 1998 by Jim Gronning. Jim started his career as a machinist in the aerospace industry in 1977. He is a Journeyman machinist certified by the state of California. The Journeyman certification is highly respected and sought after in the aerospace industry. To obtain this certification Jim served a formal apprenticeship where he completed over 4 years of training on various machine tools with rigorous course study in manufacturing technology. Upon completion of his extensive education and on the job training, Jim machined and built testing equipment contracted by Rocketdyne, Wyle Laboratories, and JPL. He specialized in atmospheric controlled machining. Using this machining process, Jim manufactured high quality parts with extremely close tolerances that were used by Boeing Defense, NASA, and the Department of the Navy.

 

Gruning's Dedication to Quality

At Gruning Precision, Jim has been able to apply his many years of experience towards building extremely accurate and high quality custom rifles and components. When Jim founded Gruning Precision, he was determined to combine the quality and attention to detail of old world craftsmanship with the precision of modern machine tool technology. Our rifles have been tested and proven by many professionals in both Law Enforcement and military. We listen to our customers in order to develop new technology that will better suit the professional in the field. This has led Jim to develop a dependable line of quality Gruning products including scope bases, rings, night vision rails, and shooting platforms. All products and custom rifle modifications are proudly done at our facility in Riverside, California. Gruning Precision will always provide you with the satisfaction of a quality custom rifle and components.
