“REMAGE” Remake — Converting Remington to Barrel Nut System

REMAGE Project Report by Bill, Rifleshooter.com Editor
Installing a new barrel on your Remington 700 (especially without a lathe) may seem like a daunting task, but thanks to companies like McGowen Precision Barrels, there are easier alternatives. By adopting a Savage-style barrel nut on a 1 1/16″ thread for a Remington 700 receiver, pre-chambered (aka “pre-fit”) barrels can be easily swapped with just a few hand tools. This system is sometimes called a REMAGE conversion (for “REMington savAGE”). With simple tools a “Pre-fit” 6mmBR-chambered barrel was installed on the author’s Remington action — no machining or lathe-work required.

Using a few tools from Brownells: Remington 700 Action Wrench, Barrel Vise, Go and No-Go Gauges, Recoil Lug Alignment Tool, and a Savage Barrel Nut Wrench, I was able to swap the .308 Winchester barrel off of my Remington 700 short action and install the new McGowen pre-fit, pre-chambered barrel, converting it to a tack-driving 6BR (aka 6mmBR Norma).

The existing barrel is simply removed from the action (normally the hardest part) and the new barrel is screwed on with the Go Gauge in place. After headspace is verified with the Go Gauge, the barrel nut is tightened against the action and you are off to the range. It takes all of the machine work out of the barreling process.

Note: Because barrel nut has a slightly larger diameter, some stocks may require minor inletting. Also, if you are shooting fired brass from another rifle with the same chambering, you should FL-size the brass before loading it for your new pre-fit barrel. And always check the set-up with a dummy round loaded to normal cartridge length BEFORE you head to the range. With Pre-Fits, the freebore should be adequate for your cartridge, but always check and adjust your seating depth as needed.

My McGowen Remage barrel looks and shoots great. I’ve written two longer articles that provide greater detail about this project.
