Tikka .204/20 CAL Match Grade Barrel


Available Options


Here at Mountain Tactical Company, we take accuracy seriously.  Most of our staff shoot competitions and, like our customers, only find accurate rifles interesting.  Deciding on a barrel manufacturer to trust our reputation on was no small task.

We are in an amazing age of manufacturing.  It is difficult to make a bad barrel!  There are many top-notch barrel manufacturers in the US.  Being a Montana based company, our decision was biased towards a Montana barrel company.  With several to choose from, we tested each barrel maker for turn time, consistency, and customer service.  McGowen Precision Barrels rose to the top of the list and we are proud of the partnership our two companies have forged.

Tikka barrel profiles require a specific shank diameter for proper mating to the receiver ring.  Every Mountain Tactical Company barrel is custom contoured to match the unique geometry of the Tikka rifle.

Contouring is done on state-of-the-art CNC equipment.  Unlike most other companies that offer barrels only at certain lengths, our barrels are contoured to your requested finished length.  Therefore, if you order a Tikka CTR contour, the muzzle diameter will be .783” whether your finished length is 20” or 26”.  

Our barrels are polished unless otherwise specified.  This is not a lathe turned finish, but an actual polished finish.

All barrels are precision button rifled, stress relieved, and hand lapped to ensure consistency and ease of cleaning.  Prior to shipping, every barrel is air gauged to confirm measurement and consistency.

There are a lot of debates out there about how many lands/grooves make the most accurate barrel. We can say that without a doubt that we have yet to manufacture a barrel that isn’t inherently accurate.

Fluting refers to the removal of material from a cylindrical surface, usually creating grooves.

The main purpose of fluting is to remove weight, and to a lesser extent increase rigidity for a given total weight or increase surface area to make the barrels less susceptible to overheating for a given total weight. However, for a given diameter, a non-fluted barrel will be stiffer and able to absorb a larger amount of heat at the price of additional total weight. There is a lot of information, or misinformation on the web concerning fluting. One piece of misinformation is that a fluted barrel is stiffer than a non-fluted barrel. This is in error. A fluted barrel of, let’s say, a CTR Contour will be stiffer than a barrel of the same weight, such as a Lite Contour. But a CTR Contour that is not fluted will be stiffer than a CTR Contour that has been fluted. It is a mass effect, the more mass around the bore of the barrel, the stiffer it will be.

Break in Procedure

To obtain the best accuracy from your new McGowen Precision Barrel we recommend that it is properly broken in. The procedures outlined below are our recommendations and not “set-in-stone” procedures, we have found that there are a wide variety of break in procedures available out there and one may fit you better than others. To get the most out of your barrel and ensure that it won’t foul in the future please use these or your ideal break in procedures.

There are two types of fouling that will affect your accuracy, copper fouling which is caused by the jacket from your bullets being stripped off in the barrel and powder fouling. Typically, the first few rounds shot through your rifle will cause copper fouling. It is very important to prevent the fouling from building up in your barrel to remove this fouling after each shot. Powder fouling is normal with any rifle or pistol and is easy to remove.


  • We have found with experience that for you to get the best results out of your barrel you should clean after each shot for the first 10 rounds or until the copper fouling stops. With all our barrels being honed and hand-lapped we have found that fouling is minimal.
  • Always use a bore guide and a good, coated rod when cleaning.
  • Use good quality phosphor bronze brushes.
  • Use good quality cotton flannel patches.
  • Use a quality bore cleaner like Butches Bore Shine or Sweets to remove any copper. Copper residue will show up as blue with these cleaners.
  • Soak your cotton patch in your bore cleaner and swab through the barrel. Once the barrel has been completely coated let sit for 30 seconds and use your phosphor bronze brush dipped in the same solution and scrub your bore (about 10 to 20 strokes)
  • Afterwards, run a clean patch through your bore until it shows no signs of copper. You may have to repeat steps 5 through 7 until it is clean.
  • Use a good bore cleaner (not a copper remover) to clean the bore completely of the copper remover afterwards.
  • After you have cleaned after each shot you will be able to tell when your bore is no longer
    copper fouling. Once you have seen this you can move on to cleaning after every 3 to 5 shot group. This should be done for the next 40 rounds.
  • After which it is probably wise for you to check your barrel after each day of shooting or at least every 25 rounds.

Q & A (1)

Hi, are your .204 barrels chambered, and threaded at the receiver end? Also, can you thread the muzzle (M18x1). Looking for the CTR profile in 25", stainless and possibly fluted.

Many thanks,

( Chris Stevenson, 10/09/2017 )

Hi Chris,

All of our custom barrels need to be chambered, threaded and installed by your local gunsmith, as we offer no gunsmithing services at this time.

Thanks for your inquiry!
