Description
EGW makes some of the best bang-for-your-buck scope bases out there, and this one is purpose-built for the Weatherby Mark V 9-lug Magnum long action. It's a one-piece Picatinny rail, so instead of fiddling with two separate bases and trying to get them aligned, you get a single solid platform that bolts right onto your receiver. The full-length cross slots run the entire length of the rail, which means you've got plenty of room to slide your rings forward or back and dial in the perfect eye relief with just about any scope you throw at it.
Why the 20 MOA Cant on This Mark V Rail Matters
The 20 MOA built into this base is the big story here. That forward slope gives your scope extra elevation travel, which is exactly what you want when you're reaching out to longer distances. EGW suggests the 20 MOA option for shooting in the 500 to 1000 yard range, and they recommend zeroing at 200 yards when you run this cant. If most of your shooting lives inside 500 yards you'd want a flat 0 MOA base instead, but for the long-range crowd this is the ticket.
Built Tough and Fits the 9-Lug Mark V
This rail is machined from solid 7075 T6 aircraft-grade aluminum and finished in a Type III hard coat anodized matte black, so it'll shrug off the knocks and weather that come with real hunting and range time. It's cut to MIL-STD 1913 specs, so it plays nice with any standard Picatinny or Weaver rings. The mount comes beveled on both sides, making it ambidextrous, and it keeps a low profile sitting right around a third of an inch above the receiver. One thing worth noting: this base is made for the 9-lug Magnum Mark V specifically, with a center spread of 4.485 inches, so it's smart to measure your receiver's hole spacing before ordering to make sure you've got the right fit.
Easy Install on Your Weatherby Mark V
EGW includes the mounting screws and the Torx wrench right in the box, so you're ready to go out of the gate. A drip of blue threadlocker and torquing the screws to around 20 inch-pounds is all it takes to lock this thing down solid. It's a straightforward afternoon project that gets your glass mounted right the first time.

Frequently Asked Questions
Will this EGW rail fit my Weatherby Mark V?
This base is made specifically for the 9-lug Magnum Weatherby Mark V in the long action configuration, with a center spread of 4.485 inches. It will not fit the 6-lug TRR actions, which use a different base. Measuring your receiver's hole spacing before you order is the best way to confirm it matches your rifle.
What does the 20 MOA cant actually do?
The 20 MOA is a built-in forward slope that gives your scope additional elevation adjustment, letting you dial for targets at longer distances without running out of travel. EGW recommends the 20 MOA option for shooting in the 500 to 1000 yard range. If you mostly shoot inside 500 yards, a 0 MOA base is the better pick.
What rings do I need for this Picatinny rail?
The rail is cut to MIL-STD 1913 Picatinny specs, so any standard Picatinny or Weaver scope rings will work. The full-length cross slots give you lots of flexibility to position your rings and get your eye relief just right. Rings are sold separately.
Does everything I need to install it come in the box?
Yes, the mounting screws and a Torx wrench are included so you can get it on your rifle right away. EGW recommends torquing the screws to about 20 inch-pounds with a drop of blue threadlocker for a secure hold. The threadlocker is not included and is worth picking up separately if you don't already have some.
