Our Legacy of Quality

Since John Krieger embarked on his journey of rifling barrels in 1982, Krieger Barrels has proudly continued the tradition of crafting barrels made in America, by shooters, and for shooters. Over the years, our unwavering dedication has played a significant role in supporting and advancing shooting sports not only in the United States but also across the globe.

The Importance of Steel

At Krieger Barrels, we recognize that the foundation of a superior barrel lies in the quality of the steel used. We leave no stone unturned when it comes to ensuring the excellence of our barrels. Our rigorous process includes setting our steel specifications, conducting comprehensive metallurgical tests on various steel samples, and collaborating closely with steel mill representatives, metallurgists, and heat treaters. This meticulous approach has been a constant for over 30 years as we continuously refine steel composition and heat treatment methods.

We take pride in maintaining stringent standards for our steel, offering it in either stainless steel or chrome moly options, with both variants adhering to the same exacting quality standards from the initial steel mill quality to the final inspection of dimensions and finish.

Single-Point Cut Rifling

Our commitment to precision extends to our barrel rifling process. While our machines are state-of-the-art, we adhere to the time-tested single-point cut-rifling method, known for its unparalleled accuracy. This painstaking process involves removing an astonishingly minute .0001 inch (1 ten-thousandth of an inch) per pass, necessitating several hundred passes to rifle a barrel. The result is almost perfect concentricity between the bore and groove, a highly uniform twist rate, and no induced stress into the steel.

Notably, we refrain from any straightening of our barrels, as this would reintroduce stress into the steel. After reaming, our barrels undergo meticulous hand-lapping to eliminate tool marks. While it's true that a correctly cut-rifled barrel need not undergo finish lapping for uniformity of dimensions, we embrace this additional step for a slightly improved finish. The finish's orientation in the direction of bullet travel reduces fouling and eases cleaning, elevating the overall barrel quality.

Our commitment to excellence in rifling is evident as we lap our barrels to finishes under 16 micro-inch in the bullet travel direction, a superior benchmark compared to the government's requirement of a 32 micro-inch finish for M-14 National Match barrels.

Choose Krieger Barrels for uncompromising precision and quality in every barrel we craft. Experience the difference that decades of dedication to excellence make in your shooting endeavors.
