Description

Criterion Barrels, Inc. was founded in 1999 as a division of Krieger Barrels, Inc. in response to demands of rifle builders and firearms manufacturers for quality match grade barrels at a lower cost. Criterion rifle barrels are match grade. Our 30+ years of experience and shared history with Krieger have given us a true understanding of what match grade means. Uniformity of the bore dimension, groove dimension, and twist, and the finish produced by hand lapping are essential for the ultimate accuracy of the barrel. With our expertise we are able to control these factors and deliver an unbelievably accurate match grade barrel at a reasonable price.

Our barrels are manufactured with gun barrel quality, ordnance-grade chrome moly steel and gun barrel quality 410 or 416R stainless steel. Both materials are heat treated and double stress relieved when they arrive from the mill.

Chrome-lining

Chrome-lining will extend the life of your barrel and make it easier to clean. It is commonly thought that chrome-lining degrades the accuracy of the barrel. This is because during the chrome-lining process, material is chemically removed from the bore and then built back up with chrome, destroying the bore uniformity.

At Criterion Barrels, Inc., our unique chrome-lining process maintains bore uniformity, providing you with the advantages of a chrome-lined barrel without sacrificing accuracy.

Lapping

Most production barrels are generally not lapped; however, the lapping process is absolutely essential for accuracy. For this reason, before chambering and crowning operations, we lap the bores to remove reamer rings and to improve the surface finish and bore uniformity.
