Kimber Mountain Ascent Mojave 280AI 24-inch Rifle
About this product
The Kimber Mountain Ascent Mojave is a purpose-built bolt-action rifle designed for lightweight, precision field use. Chambered in 280 AI with a 24-inch match-grade threaded stainless steel barrel, this Kimber Mountain Ascent Mojave 280AI 24-inch rifle combines a rigid aluminum bedding block with a featherweight HS Precision fiberglass/carbon/Kevlar fixed stock. The action includes a fluted bolt body, hollow bolt knob, and an adjustable factory trigger to support consistent accuracy. Finish and hardware are supplied in Kimber’s KimPro II black finish, and the rifle ships with a 5/8×24 adapter, sling, and premium nylon rifle case.

Key Features
- Match-grade 24-inch threaded barrel: Why it matters — the stainless steel barrel is button-rifled and threaded 5/8×24, so you can mount a suppressor or brake without losing precision.
- HS Precision fiberglass/carbon/Kevlar stock: Why it matters — this fixed stock saves weight without sacrificing rigidity, keeping your point of impact consistent even after a long hike.
- Fluted bolt and hollow knob: Why it matters — reduces overall weight by several ounces and allows smoother cycling, which helps you stay on target for follow-up shots.
- Adjustable factory trigger: Why it matters — you can dial the pull weight from about 2.5 to 4 lbs without aftermarket parts, giving you a crisp break for long-range accuracy.
- KimPro II black finish: Why it matters — this coating resists rust and scratches better than bluing, so the rifle holds up in wet or dusty field conditions.
Who It’s For
This rifle is for the hunter or shooter who wants a lightweight mountain gun that still shoots sub-MOA. If you’re packing into backcountry elk or mule deer country and need a rifle that won’t weigh you down but still delivers precision at 500+ yards, the Mojave fits. It also works for the reloader who wants to push the 280 AI cartridge — it gives you 7mm magnum ballistics in a 5.3-pound package.
Pros and Cons
- Pro: Under 5.5 pounds with a 24-inch barrel — one of the lightest production rifles in its class.
- Pro: The 280 AI chambering offers flat trajectory and retained energy comparable to a 7mm Rem Mag with less recoil.
- Con: The lightweight stock can amplify felt recoil compared to a heavier synthetic or wood stock. Plan to use a quality brake or suppressor if you’re sensitive to recoil.

The Kimber is lighter and more affordable than the Geissele, while the Timney action-only option requires you to build the rest. For a complete, ready-to-hunt rifle, the Mojave offers the best weight-to-value ratio.
