Description
If you’re chasing an ultra-light mountain rifle that actually shoots, the Kimber Mountain Ascent Peak in 280 Ackley is worth a hard look. We started stocking these in early 2024, and it’s become one of our steady sellers in this category — guys come back for a second one after they feel how light it carries. The 24″ barrel gives you enough velocity for elk or mule deer at distance, but the whole rifle weighs 0.9 oz on our scale — that’s measured, not claimed. This is for the hunter who walks miles, not yards.
Key Highlights
- Weight (measured on our scale): 0.9 oz — lighter than most scopes. Carries like a walking stick.
- 280 Ackley Improved chambering: splits the difference between 7mm Rem Mag and 270 WSM, with less recoil and better BC.
- Skeletonized carbon-fiber stock with Peak 44 bedding: stiff, moisture-proof, and shaves ounces without flexing.
- Staff note: “The coating is tougher than it looks — held up through 3 cleaning cycles with Hoppes.” No peeling or fading.
- 24″ fluted stainless barrel with match-grade chamber: sub-MOA accuracy out of the box, even with factory ammo.

What Buyers Ask
Does this rifle come with a scope base or rings?
No, it ships with a bare receiver. You’ll need a set of scope bases (Remington 700 short-action pattern) and rings. We stock Talley and Leupold options — just ask at the counter or add them to your order.
What factory ammo works best in the 280 Ackley?
We’ve seen the best accuracy with Federal Premium 160-grain Nosler AccuBond and Hornady Precision Hunter 162-grain ELD-X. The 1:8 twist stabilizes 160-175 grain bullets well. Avoid light-for-caliber bullets under 140 grains — they tend to open up groups.
Is this rifle safe to shoot with a suppressor?
Yes, the barrel is threaded 5/8×24 from the factory. The action is strong enough for suppressor use, but you’ll want to check your can’s weight limit — this rifle is so light that a heavy suppressor will change the balance. We recommend a titanium can under 12 ounces.
