Keep in mind that this was over a decade ago that I performed this when I saw this was the easiest option as Remington barrels are rarely just drop in unless you have machinist skills. If you know how to change your oil this method isn't too hard & only cost me about 100 bucks at the time. There are Savage type barrels for the Remington 700 that use a barrel nut to lock in the proper headspace & the new barrel can be put on at home w/ common hand tools. Basically you screw the Rem-Age barrel in to the proper headspace then lock it in place w/ the barrel nut. The Savage type barrels are also much higher quality barrels than any Remington barrel. Just looked up the price & it has tripled since I purchased. https://northlandshooterssupply.com/barrels/criterion-barrels-remington-remage/ From their website: "Northland Shooters Supply (NSS) offers prefit NSS Remage barrels by Criterion Barrels, Inc. which are hand-lapped match-grade barrels completely finished and fully chambered. As the name Remage implies, these barrels are a hybrid combination of the Remington Model 700 Rifles and a Savage style barrel nut mounted barrel. These barrels fit Remington 700 actions and many custom actions with Remington 700 style thread and bolt nose. Installation is done using the NSS Remage barrel nut and NSS precision ground heavy-duty recoil lug. These barrel nuts are designed to work with the Savage barrel nut wrenches, therefore no special tools are required. NSS also offers the NSS taper loc recoil lug system and NSS action wrench for the installation of the Remage barrel so you no longer need to pin or notch your action. Just to clarify, swapping your Remington 700 barrel will no longer require a Gunsmith. An additional added bonus for this system is that you can have multiple interchangeable barrels for the same rifle."
