Description
Left-handed hunters usually get the leftovers, so it says a lot that Weatherby built the Mark V Backcountry Guide as a dedicated LH rifle chambered in 6.5 Weatherby RPM, a cartridge designed from the ground up for the six-lug Mark V action. The whole package weighs 5.6 pounds bare, which you will appreciate somewhere around the third ridge of a backcountry mule deer hunt. The 22-inch BSF carbon fiber barrel keeps weight out front to a minimum, sheds heat quickly, and comes threaded 5/8-24 with Weatherby's Accubrake ST installed, so it plays nice with suppressors too. A 1:8 twist stabilizes the heavy, high-BC 6.5mm bullets the RPM was built to push.
Peak 44 Blacktooth Stock and Built-In Spartan Adapters
The Blacktooth from Peak 44 is one of the lightest production carbon fiber stocks you can get, finished here in a green and tan sponge pattern with a carbon bedding block underneath. Weatherby went a step further and factory-installed Spartan Precision gunsmith adapters in the forend, so a Spartan bipod snaps on and off magnetically without tools or extra hardware. The 3DHex recoil pad uses a printed honeycomb structure to soak up recoil, and between that, the brake, and the mild-mannered RPM cartridge, this rifle is genuinely pleasant to shoot for something this light.
Backcountry Guide Accuracy You Can Count On
Every Mark V ships with Weatherby's sub-MOA guarantee, a three-shot group under an inch at 100 yards with quality factory ammo, and the externally adjustable TriggerTech trigger with its zero-creep break makes hitting that mark a lot easier. The spiral-fluted bolt runs a short 54-degree throw for fast follow-ups and plenty of scope clearance, feeding from a 4+1 hinged floorplate magazine. Graphite Black Cerakote covers the metalwork to shrug off weather, and the receiver comes drilled and tapped with no sights, ready for the glass of your choice. For the southpaw who hunts hard country, this one checks every box.

Frequently Asked Questions
Is the Weatherby Mark V Backcountry Guide LH a true left-handed rifle?
Yes, this is a dedicated left-hand configuration of the Mark V action, not a right-handed gun with workarounds. The bolt handle and port are on the left side, so lefties get the same smooth 54-degree bolt throw and fast cycling that righties have enjoyed on the Mark V for decades.
What is 6.5 Weatherby RPM and how does it compare to 6.5 Creedmoor?
The 6.5 Weatherby RPM (Rebated Precision Magnum) was designed specifically for the slim six-lug Mark V action. It pushes the same high-BC 6.5mm bullets noticeably faster than a 6.5 Creedmoor, which means a flatter trajectory and more retained energy at distance. It is a great fit for deer, antelope, and even elk at reasonable ranges, and the 1:8 twist handles heavy bullets well.
Can I run a suppressor on the Backcountry Guide's 22-inch barrel?
You sure can. The barrel is threaded 5/8-24, so once you remove the included Accubrake ST, most common suppressors thread right on. The shorter 22-inch carbon barrel is one of the reasons Weatherby built the Guide series this way, since it keeps overall length manageable with a can attached.
Does this rifle come with an accuracy guarantee?
Yes. Like all Mark V rifles, the Backcountry Guide is backed by Weatherby's sub-MOA guarantee, meaning a three-shot group of .99 inches or less at 100 yards from a cold barrel with Weatherby factory or premium ammunition. Independent range tests of the Guide series have reported groups well under that mark with quality hunting loads.
