Fitting, Services and Additional Parts

Krieger Barrels offers a full range of services on our bolt gun barrels, AR-15, AR-10, M110, M1 Garand, M1A and M1903 barrels. Whether you are looking for a rough or short chamber, a full chamber and headspace, assembly of your AR, bolt or M1. Even if you would just like to add flutes or muzzle threads, Krieger Barrels has you covered.

Why don't we just offer prefit or drop in bolt action barrels? At Krieger Barrels we believe a premium match grade barrel deserves a custom fitting to ensure proper headspacing with your bolt. Therefore, you can have us do it, or you can send your Krieger blank to a trusted local gunsmith. (Don't have one? Start here. Note: This is just a resource, not an endorsement from Krieger.)

If we find that a particular receiver and cartridge can be sold prefit and still maintain premium accuracy, we offer it. This is why Krieger Barrels does offer AR-15 barrels finish chambered with a timed barrel extension that are ready for your upper (mil-spec bolts only).

      Additionally, we do perform full fittings on the following receivers:

      • US “Enfield” Model 1917 (also P-14)
      • US Springfield 1903, 1903-A3, 1903-A4
      • Lawton Actions
      • Stiller: Predator, TAC 30, TAC 300
      • Surgeon 591, 1086
      • Savage 110, 112, 10, 12, Target
      • Remington: 30S, 40x, XP-100, 600, 660, Model 7, 78, 700, 720, 721, 722, 725
      • Winchester: Model 70 (pre-64, post-64, and Classic) 16 pitch thread ONLY , 54, 670
      • FN SPR

      Remember the lists above are just the receivers we work on and the chambering reamers we keep in stock. We make unchambered, rifled blanks for many more calibers. If you do not see a particular action on our list, it has nothing to do with the quality of the action. In some cases, the opposite is true as some very high-end benchrest actions really require a great deal more time and care than we are able to dedicate to the fitting. Please note that we cannot perform any fittings or chambering with a customer supplied chambering reamer regardless of its origin. Always be sure the cartridge you request is appropriate for your action.

      Chambering Options:

      Full Fitting:

      Full fitting of your new Krieger Barrel to your receiver. This requires that you send us all of your parts which are necessary for the fitting. Click here to download our parts send-in check list. Fill this out and send it with your parts.
      Price:
      With Extractor Cut: $290
      No Extractor cut required: $270

      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.

      Truing Services, Level I:

      Price: $100.00

      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
