Owners of the Mark V Frontier chambered in 378 Weatherby Mag tend to praise the rifle's fit and machining. The Mark V action has a long reputation for a strong, well-locked bolt, and the factory TriggerTech Field trigger draws particular praise for a clean break compared to typical factory triggers. Some owners note that a rifle this powerful takes practice before the shooter is fully comfortable behind it.

In the field, owners like having a drilled and tapped receiver ready for an optic alongside the factory iron sights as a backup, and the Cerakote finish holds up well to weather and handling. The Accubrake ST is frequently mentioned as making the big chambering noticeably more manageable, though some hunters wish it were quieter for people standing nearby.

Value opinions vary. Some owners feel the Mark V Frontier is a fair price for a dangerous-game-capable rifle with a finished stock, upgraded trigger, and threaded barrel from the factory, while others consider big-bore Weatherby rifles a premium purchase overall. Aftermarket parts and gunsmith support for the Mark V platform are well established.
