Contouring The majority of our contouring is done using state-of-the-art cnc equipment to give you the exact profile that you are looking for. Our cnc turning center was purchased brand new July 2007 and because it is new and well maintained, the tolerances we can offer are unsurpassed in the industry. Combined with our machinist(s) vast experience in programming we are able to duplicate just about any contour that your imagination can come up with. And if you are interested in multiple barrels with the same specifications, our machine allows us to match them exactly. Many barrel companies offer only one standard contour and anything that isn't listed as their standard contour would cost the customer an additional fee to program it. The funny thing is that once the barrel contour has been programmed it is saved in memory for use later down the road. But many companies continue to charge a surcharge for any contour not listed in their "standards" even though there is absolutely no further programming work required to reproduce it. We have a different perspective on this. We know that there are many customers who are used to certain contours from other rifle barrel makers or from the firearms makers. We have sat down as a company and made the decision to consider all rifle barrel makers contours as our standards. This gives us a huge variety of contours for the customer to choose from without having to pay an upcharge fee. If there is a contour from a current rifle barrel maker or firearms company that you don't see listed below, please contact us and we'll do the leg-work to find the dimensions and reproduce it for you. Many barrels that you purchase are in what most call a lathe-turned finish. What is a lathe-turned finish? Basically it is the finish that the companies cnc turning center (or whatever they are using) leaves the finish at. It is unfinished in our opinion therefore we send all barrels out in a polished finish unless otherwise specified. We can also send it out with what we call a matte finish. This is accomplished by bead blasting the barrel with very fine glass beads. The advantage of a matte finish is the anti-glare properties of it, but it also helps in cooling. How can this be? Think about it this way, when you bead blast a rifle barrel you are basically putting millions of tiny little dents into the barrel, and with all these dents you have increased your surface area (just like fluting).
Octagon & Dodecagon Barrels
We also offer Octagon barrels for your lever action, single shot or bolt action rifles. Your octagon can be a tapered octagon, 1/2 round 1/2 octagon, straight octagon or a 2 step octagon. We have also added Dodecagons to our line up (see image above). This is a 12 sided barrel that gives you both an octagon and round contour feel in the same barrel. Octagon barrels vary quite a bit from manufacturer to manufacturer in their dimensions. When ordering an octagon or dodecagon barrel please submit as detailed dimensions as possible. This includes overall length including section for threading, what type of firearm it is going on, measurement across the flats at the breech and muzzle ends, length of octagon section if doing a 1/2 round 1/2 octagon, length of wedding ring at the front of the receiver (if required), diameter of round section at end of octagon and at muzzle end on 1/2 round 1/2 octagons.
Fluted Barrels
Fluting is another option for your round barrel. We offer either 6 or 8 flutes on our barrels as standard. 6 flutes are more typical of what you would see on a factory rifle and allows us to make the flutes a little wider than 8 flutes. Please keep in mind that for safety we will only flute certain contour/caliber combinations. Typically a #3 Regular Sporter type contour in a small caliber is the minimum diameter we would go. There is a lot of questions out there regarding fluting and what it actually does for you. Here's a basic low-down on fluting. Fluting increases the surface area on your rifle barrel which helps in the cooling. It only removes ounces from the weight of your barrel, not pounds. A good rule of thumb is that fluting your barrel will usually bring its weight down to the next contour size. Fluting does not make your barrel stiffer. This is a misconception out there. Here's an example: A #4 contour that is not fluted will be stiffer than a #4 that is fluted. A #4 that is fluted will be stiffer than a #3 contour that is not.
Crowns Part of the finishing touches on your rifle barrel is its crown. The crown is a very important part of the accuracy of your rifle. A damaged crown can cause your accuracy to suffer. Below are the standard crowns that we offer. Crowning is an addition to the contoured blank cost.
