Description
If you're mounting glass on a Remington 700, Weatherby Vanguard, or Howa 1500, this Warne Vapor two-piece base set is one of the simplest ways to get there. It's machined from lightweight aluminum, finished in a clean matte black, and built to the Weaver-style cross-slot pattern that works with a huge range of Weaver and Picatinny-compatible rings. Two separate pieces mean the ejection port stays clear, which keeps loading and unloading hassle-free.
What the Warne Vapor Base Fits
Warne built this set around the popular Rem 700 footprint, so the fitment list runs long. Beyond the Remington 700 (short and long action, ADL and BDL), it covers the Weatherby Vanguard, Howa 1500 and 1700, plus a bunch of other Rem 700-pattern actions like Bergara B-14, Christensen Arms bolt guns, Nosler M48, and the Mauser Model 18. If your receiver follows the 700 drill pattern, odds are good this base is a match.
Setting Up the Vapor Scope Base
Installation is about as straightforward as it gets. The set uses 6-48 screws, and Warne suggests snugging everything up to no more than 25 inch-pounds of torque with a removable thread locker on the base screws for the best hold. A good tip is to loosely assemble your rings and scope first to dial in eye relief and ring spacing before you lock it all down. The low-profile design keeps your scope sitting close to the bore, which plenty of hunters prefer for a natural cheek weld.
Why the Vapor Line Earns Its Keep
Warne has been building mounts since 1991, and the Vapor series is their value-focused option that still delivers real-world durability. The aluminum construction keeps weight off your rifle without giving up strength, and these bases handle magnum recoil without complaint. It's a dependable, Made-in-USA foundation that backs up a lifetime warranty, making it an easy choice for a new build or a scope upgrade on a rifle you already trust.

Frequently Asked Questions
Is the Warne Vapor base Weaver or Picatinny style?
This base set is cut in the Weaver style. Because Weaver and Picatinny share a similar cross-slot layout, most rings labeled Weaver or Weaver/Picatinny-compatible will mount up just fine. If your rings are strictly Picatinny-spec, double check the slot dimensions before ordering.
Will the Warne Vapor base fit my Howa 1500?
Yes, the V402/476M is designed to fit the Howa 1500 and 1700 actions, including short and long action variants. It also covers the Remington 700 and Weatherby Vanguard, since all of these share the common Rem 700 drill pattern. A good number of owners run it on the Howa 1500 without any trouble.
Does this come as one base or a complete two-piece set?
The listing is for the complete two-piece set, so you get both the front and rear base in the box. You won't need to buy a second piece. Mounting screws are included as well.
Do I need to buy rings separately for the Vapor base?
Yes, rings are sold separately. This is a base-only set that gives your rings a solid platform to clamp onto. Warne's own Vapor rings pair nicely with it, but any quality Weaver-style rings will work.
