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 and Criterion, 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.
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.

Superb Accuracy with Criterion Pre-Fit Barrel and Creedmoor Sports Ammo
Check out that 0.188″ group. Can you believe that was shot with factory .308 Win ammo? A while back our friends at Criterion Barrels tested some .308 ammo from Creedmoor Sports. This was loaded with Lapua’s 175gr Scenar HPBT bullet in Lapua brass. The results speak for themselves. Any time factory ammo can shoot inside quarter-MOA, that’s impressive. This ammo was used in a “Rem/Age” project rifle. That term refers to a Remington action rifle that has been re-barreled with a pre-fitCriterion barrel. The new barrel is secured with a Savage-style barrel nut. Hence the term “Rem/Age” or “Rem-Age”.
Criterion posted: “I think we may have a new favorite factory match load for the nitrided Rem/Age build.” Another reader added: “[Creedmoor’s] 175 Scenar .308 ammunition is top notch.” FYI, this group was shot on our load development target, which you can download for free from our Targets Page.
Why do Criterion barrels shoot so well? One reason is that Criterion’s barrel steel is carefully stress-relieved. In the photo below, Criterion Rack 1A (aka the “Coffin”) has been loaded with barrel blanks — made ready for the stress-relieving process.
Working with Pre-Fit Barrels
While they may require the purchase of some additional tools and a bit of a learning curve to install, using Rem/Age pre-fit barrels offer advantages over gunsmith chambering and barrel-fitting. In this video, 8541 Tactical explains how to install a Criterion 6.5 Creedmoor “pre-fit” barrel. You save money and time — you don’t have to wait for a gunsmith to chamber the barrel. While Criterion recommends that a competent gunsmith oversee the pre-fit installation, if you understand the use of go/no-go gauges and you have a barrel vise and action wrench set up to remove the original barrel, putting on a pre-fit barrel CAN be a DIY project. You don’t have to pack up your rifle to ship it off to a smith.

In our Shooters’ Forum, you’ll find a lengthy thread about accuracy problems with a Savage LRPV, chambered in 6mmBR. The gun would repeatedly split groups at 100 yards, and at 300 yards, the “flyers” would open up the groups to 1.5 MOA or larger. Interestingly, the factory test target (at right) showed a split group — not a good sign.
The gun’s owner, forum member LR_Shooter, tried a variety of tweaks: “I did this, done that… [changed] torque, tang floated, bedded action, recut chamber, and [adjusted firing pin]”. But nothing really helped. Frustrated, LR_Shooter asked his fellow Forum members for help. Much advice was proffered, including the novel idea of removing the middle action screw in the Savage 3-screw target action. Some of the advice proved helpful, but none of the suggested remedies produced a major improvement. This rifle, out of the box, tossed flyers and no amount of tweaking (or changes in shooting technique) really cured the basic problem. That is, until, the factory barrel got replaced…
New Criterion Pre-Fit Barrel Works Wonders
LR_Shooter acquired a Criterion pre-fit barrel from Jim Briggs at Northland Shooters Supply (NSS). These pre-fits are designed for easy installation with the standard Savage barrel nut. Wouldn’t you know it, with a new 30″ heavy-contour barrel on the LRPV, the gun started shooting way better. No more crazy fliers, no more split groups, no more excessive vertical. And the improvement came without any other major modifications.
LR_Shooter reports: “I got a replacement barrel from Jim at NSS. It is a 30″ bull Criterion barrel. So far, without playing with torque screws and having my old setup… I’m very satisfied with the barrel I got. Now I have no problem getting [groups] under 0.25 MOA. Finally this thing can shoot!”
Targets Shot with Savage LRPV Fitted with Criterion Barrel
The targets above, shot with the new Criterion barrel, speak for themselves. The left target was shot at 100 yards, while the target on the right was shot at 300 yards (very impressive).
Moral of the Story — Sometimes A New Barrel Really Is the Right Solution
All of us have struggled at times with a rifle that won’t live up to expectations. This Editor personally struggled for over a year with a .260 Rem Savage with a factory tube. The gun tended to split groups and the POI walked as the barrel heated. I tried one powder/primer combination after another, working through a variety of seating depths over many months. I was persistent. Out of stubbornness, I just believed that sooner or later I’d find the magic load.
Well folks, sometimes there’s really nothing you can do about a sub-par barrel. It is what it is. To really improve a gun’s accuracy (particularly a gun with a factory tube), you may need to open your wallet and get a quality aftermarket barrel. Spending months trying one recipe after another may simply be an overwhelming waste of powder, bullets, and your precious time.
Albert Einstein supposedly said: “Insanity is defined as doing the same thing over and over again, and expecting different results.” Well that sort of describes my efforts with my .260 Rem. Once I had enough evidence that my barrel split groups no matter what load combo (and seating depth) I tried, it was time to pony up for a new barrel. When I did finally screw on a nice PacNor 3-groove Supermatch, that Savage suddenly became a true tack-driver. As re-chambered in 6mmBR with the Pac-Nor, in calm conditions, my Savage will now consistently shoot in the twos with heavy bullets, and it can sometimes dip down into the ones with Berger 80gr flat-base bullets. The moral of the story here is simple — don’t waste weeks or months chasing your tail with a barrel that just won’t deliver (after a reasonable amount of testing). Save up for a custom barrel, get it chambered properly, and stop your cycle of frustration.

We have always liked Tikka actions, and now there is a great re-barreling option for Tikka T3 owners. Criterion Barrels Inc. (CBI), makers of “pre-fit” barrels for Savage, Remington, and Rem-clone actions, will soon be offering Tikka pre-fits. These pre-chambered barrels for Tikka T3 actions will be headspaced with a barrel nut, just like a Savage.

The new Tikka T3 pre-fit barrels will be sold through Solid Accuracy, a respected Texas-based outfit that sells high-end scopes, stocks, barrels and other rifle components. Criterion tells us: “The Solid Accuracy barrel nut and wrench design has been finalized, the prototype barrels tested and the barrel nuts are now going through production (with an expected ETA of 2-3 weeks). All orders for these pre-fits barrels are currently heading out to the shop floor for production. Orders placed this week can expect a conservative estimated lead time of 14-16 weeks.”
The accuracy has been impressive with Solid Accuracy’s test rifle, which features a Tikka T3 action mounted in a KRG X-Ray chassis. This prototype rifle is chambered in 6.5 Creedmoor. The group below was shot with a stout load of H4350 and Sierra 140 grain MatchKings seated .009″ in the lands.
The folks at Criterion are excited about the Tikka pre-fit project: “We’re looking forward to getting these barrels out the door and on to some custom rifle builds.” One of Criterion’s staffers was so impressed with the initial test results that he is building his own T3 project, with a Criterion pre-fit of course…
