Contours

Krieger Barrels offers a wide variety of both standard and custom barrel contours for bolt action rifles as well as AR10, AR15, M1 Garand, M1A/M14 and service rifles. Whether you would like to choose from one of our standard Sporter, Match Taper, Palma profile or straight contours, or if you would like to copy your existing barrel's profile or create your own custom profile, Krieger Barrels has you covered. If you don't see the profile you need for your custom rifle build or your replacement barrel give us a call or submit your question here.

Stay service rifle competition legal with our AR15 DCM profile or upgrade to our heavy Varmatch barrels and add weight and length to your AR15 as well as custom lengths and muzzle diameters. Our AR10 DPMS heavy contour barrels are available in multiple calibers as well as custom lengths and muzzle diameters while our M110 is kept NRA service rifle match legal in .308. Our M1 Garand and M1A barrels are available in multiple service rifle competition patterns. Get your Springfield M1903 or M1903-A3 in parkerized chrome moly as a .308 or .30-06.

Most of these contours have multiple available options and services, from fluting and parkerizing to fitting, assembly and chambering.

    If your are looking to replace your existing barrel but it doesn't match any of our standard contours exactly or you are not sure of all the proper dimensions we can make a new barrel with the same contour as your original barrel. Just send us the barrel and we will match the contour for you. Ask us about it.

    If the barrel you are looking for doesn't match any of our standard contours exactly, we can create a custom contour to your specifications. This contour must meet our own strict minimum contour requirements for safety. Beyond the safety requirements we are quite flexible in the contours we can provide and can increase the level of precision on ground diameter dimensions. If you are looking to get a standard barrel type (i.e. Sporter, Match, Palma) and just wish to substitute some of the standard catalog dimensions for different ones, ask us about it here..
