Savage Drop In Barrels
4D Products offers drop-in barrels for Savage actions.  Savage offers two barrel thread diameters so you must indicate the diameter of your threads (explanation of how to determine barrel diameter at botom of page).

Each barrel is threaded for your receiver, crowned with an 11 degree target crown and fully chambered (any chamber reamer we have).  Below is a list of available contours, all for Savage drop-ins.  If your not sure what taper we suggest you select one of the Savage factory contours so that it will fit your existing stock.

Model 12BVSS Varmint Series Stainless barrels are offered either polished or matte finish at no extra charge.  Shipping included, $345 to the United States only.

Chrome-Moly barrels are offered either matte or factory polish (320 grit) blued.  Shipping included, $320 to the United States only.

There are five(5) steps. Please make your selections below.
These barrels are custom manufactured for 4D by McGowen Precision Barrels.

Barrel Shanks

Standard barrel shank diameter on 06 class and belted style cartridges are 1.055" x 20tpi.

When Savage started offering rifles in the Winchester Short Magnum (WSM) and Remington Ultra Magnum (RUM) calibers, there was a change made to the barrel shank diameter. On the new WSM, RUM, and RSAUM calibers it is 1.120" x 20tpi. The barrel nut is also bigger in internal size, but is the same outer diameter and our rental barrel nut wrench will still fit.

However, there were very few WSM and RUM rifles made on the standard barrel shank during the first production run. To be certain, measure the barrel shank right against the nut. The larger barrel shank will have a step down approximately 1/8" ahead of the barrel nut. If your rifle has a serial number with a "G" prefix, it is most probable it will have the larger shank.
