The term “rebarreling” is thrown out a lot in the gun space, but what is it? Why would someone do it? And how?

Rebarreling, in the simplest explanation, is replacing the barrel on an existing rifle. That’s great, but why? There are several reasons as to why you would want to rebarrel a rifle.

Why Rebarrel:

1) The rifle is not performing to your desired standards, even with accurization of the shooting system.

2) You want to change the caliber of rifle – including creating wildcat cartridges.

3) You want to increase or decrease weight of the overall rifle.

4) You want to customize the look of your rifle.

Most of the time it’s reason #1 – you want the rifle you have to be more accurate. Mass manufacturers have a range of acceptable measurements for each component used. That means you may get the largest acceptable barrel measurement and the smallest acceptable action measurement. Which when assembled, really aren’t suited to fit together. This mismatch allows for slop in your bolt and misalignment in the barrel. This variance is why sometimes factory rifles shoot well and sometimes they don’t.

Custom barrels tend to be made with more precision in the blank making process. They are typically – at least when we do it – always made for your specific rifle’s action. What that means is that the rifle barrel is not made to a generic print. It’s actually made off of the exact measurements from YOUR action (measured to the .0005).  

At Horizons Firearms, we almost exclusively use Benchmark barrels. Their barrels are double heat treated in the vertical position with a marked chamber specific end. The additional care they take in their process allows for very straight and very accurate barrels. We then take the barrel blank and contour it to your desired shape. After that, the barrel hand lapped to ensure there are no internal burs on the rifling prior to chambering and mating of the barrel with the action.

Rebarrel processes may differ from gunsmith to gunsmith, but at our shop , a rebarrel is more than just replacing the barrel.

Rebarreling includes:

-Blueprinting the factory action – returning your action to its factory specs

-Replacing the barrel with a Benchmark barrel (available with or without flutes) that has been hand lapped and contoured to the customer’s specifications

-Securely bedding the action in the stock

-Applying Cerakote/KG coating

-Adjusting, or replacing, the trigger

-Test shooting the rebarreled rifle

Through this process, you can be absolutely confident that your rifle’s components are perfectly suited to shoot extremely accurately. This is why we can guarantee our rebarrel jobs to shoot .5 MOA before they leave our shop.

As an example, here’s a recent rebarrel project we did for a customer.

When rebarreling, a rifle can be chambered to just about any caliber, but our standard favorite/most popular calibers are 22 Creedmoor, 6 mm Creedmoor, 6.5 Creedmoor, 7 mm Creedmoor, 6.5-284 & 270 WSM, 7 mm Remington Magnum, .300 Winchester Magnum, and .308 Winchester.

A rebarrel is an affordable way to give your factory rifle semi-custom performance using your existing action. In return, you will receive a rifle you love to shoot that is accurate and reliable.
