Barrel replacement
- Thread starter ghughes
- Start date
It depends on the make of rifle. Lets talk about a very common rifle, the Remington 700.
To start with, Remington does not sell replacement barrels, so you are looking at buying a barrel that has been removed from a 700 or threading and fitting and chambering another barrel.
This requires a lathe, chambering tools, measuring devices, headspace gauges, a barrel vice and an action wrench and the knowledge of what to do.

I'm sorry maybe I asked this question incorrectly, maybe i should have asked how a bolt action rifle is made. I've never seen one apart. I'm not planning on rebarreling, as i've been lucky made good choices of of the rack stuff. I'm just interested in the work involved. I mean a rifle is basicly a simple machine, but to make it accurate takes precision. There are several ways to increase accuracy and in some cases a better (custom) barrel may be the choice.
Lets assume you have an old mauser (like so many that came back to North America after the war at the time these were the best availible correct?), then you decide on a caliber, lets say 25-06. There are many barrel makers out there (and have been for 50-60 years) do they provide stock barrels which simply thread into the action or is there additional machining to the barrel, action or both? Presumably there are barrels which are chambered at the factory or is this wrong? Does the extracter have to fit into the barrel base, is the bolt head surrounded by the barrel or lock up tight to it? With a barrel with no sights is it a simple matter of threading the new barrel on or is the bolt face/barrel made to fit precisely? Sorry I guess this a more complicated question than I first thought.
Thanks, G

There are barrels available for some actions with finished shanks and almost finished chambers. Or, finished chambers and almost finished shanks. The unfinished portion allows for final fitting to an existing action. Because of tolerance issues and manufacturing variations it is often not possible to manufacture replacement barrels that would be a proper fit on every action. The Savage 110 series is one of the few designs for which it is possible to purchase a completely finished replacement barrel, because Savage's locknut system allows for headspace to be set without doing any cutting.
A properly fitted barrel will have correct clearance to the bolt, correct cartridge head protrusion, proper thread fit, and headspace within specifications. If you go to Brownells.com, you will find a variety of barrels with varying degrees of completion.
