Services for your Krieger Barrel

Services and Parts

Krieger Barrels offers a full range of services on our AR-15 and AR-10/M110 barrels (drop in ready with a JP Bolt) and various services on our Bolt Action, M1 Garand, M1A and M1903 barrels. Check below to see what options are available.

We also offer complete Ruger Precision Rifle barrels that are ready to be installed on your receiver by a competent gunsmith with headspace gauges and an AR15 Barrel wrench. For most other bolt action receivers the best option is to perform a custom fitting to ensure proper fit to your bolt and receiver. Therefore, you should send your Krieger blank to a trusted gunsmith. (Don't have one? Start here. This is just a resource, not an endorsement from Krieger.)

Services by Rifle Type:

      Chambering Options:

      Rough Chamber:

      We stop reamer .100” to .200” short of finish; this saves wear and tear on your finish reamer.
      Price: $40.00

      Deep Chamber:

      A finished chamber that is .100” to .200” deep. You can use your lathe to thread, shoulder, breech cone, and set the headspace. You will still need headspace gauges which we do not provide.
      Price:
      Standard Bolt: $55.00
      50 BMG: $100.00

      Benefits:

      Flutes aid in cooling a barrel by exposing more surface area to the outside air. Flutes can also increase the rigidity to weight ratio of the barrel, thereby reducing barrel vibration and whip over a barrel of the same weight unfluted. (For example, our #8 Standard Target barrel (fluted) - weighing 5.5lb - will be more rigid than a #7 light Target barrel (unfluted) weighing 5.5lb.

      Pricing:

      Standard Bolt: Up to 30” finish length, and overall OD of 1.250” for stainless steel and 1.300” for chrome moly.
      Price: $150.00

      Oversize Barrel: Finish length in excess of 30” or overall OD greater than 1.250” for stainless steel and 1.300 for chrome moly.
      Price: $175.00

      Availability:

      Fluting is available for both chrome moly and stainless steel barrels in all calibers, as long as certain safety minimums are maintained. If you are not sure if your barrel contour meets these requirements, please feel free to call and discuss it with one of our technicians, (262) 628-8558. Flutes up to 34" long can be put on barrels up to 37” in overall length with outside diameters up to 1.350".

      Style & Dimensions:

      Our standard 10 flutes use a 3/16” cutter, start 5-7” from the breech (depending on contour), and end approximately 2” from muzzle, leaving plenty of room to mount a sight base or barrel band. We also offer 6 flutes with a 1/4” cutter at your request.

      Glass bead blast exterior finish for stainless steel. Provides a matte silver gray appearance with reduced glare.
      Price: $45.00

      There is generally a slight flare at each end from the tools and lap entering and exiting the barrel. This is why you should always remove at least an inch from the muzzle when fitting any barrel. The chambering reamer for centerfire cartridges will take care of any of this at the breech, but the relatively short chamber of a .22 rimfire requires that 1 inch be taken off the breech end of a blank as well when they are fitted. Please order your contour and blank length appropriately. Our standard catalog leaves an inch on all of our bolt gun blanks for this reason, this is why we list both blank length and finish length.
      Price: $45.00

      Chambering Options:

      Short Chamber: M1 Garand, M1903 & M1A / M14
      Chamber complete and polished except shoulder is -.010” to be finish chambered with an ordinance style “head space reamer.” Shoulder is cut to time up with the M1 Garand drawings and receivers. (Note: may not time perfectly on all commercial receivers). Includes crown muzzle.
      Price: $60.00

      Rough Chamber: M1 Garand & M1A / M14
      We stop our reamer .100”-.200” short of finish; this saves wear and tear on your (or your gunsmith's) finish reamer when the fitting is completed.
      Price: $40.00
