Features 

The PROOF Research carbon fiber-wrapped barrel is the main reason this rifle sits at 5.8 lbs — carbon fiber over a steel liner maintains rigidity and accuracy while cutting weight compared to a full steel barrel. The Melonite finish on the stainless receiver resists corrosion without adding any appreciable mass. 
 
The AccuFit stock has adjustable comb height and length of pull, so different-sized shooters can dial in a consistent cheek weld without aftermarket modifications. The factory-blueprinted action feeds and extracts reliably. The AccuTrigger adjusts from 1.5 to 4 lbs — most owners set it in the 2–2.5 lb range for field use. The threaded muzzle accepts suppressors or muzzle brakes.

The Savage 110 Ultralight in .308 Win gets consistent praise from hunters and backcountry shooters who need to carry their rifle over serious terrain.

The carbon fiber barrel is the headline feature in most discussions — owners note it keeps overall weight at 5.8 lbs without any apparent accuracy penalty. Many report good groups right out of the box, and the adjustable AccuTrigger is frequently mentioned as a meaningful advantage over fixed-trigger budget rifles.

The lightweight design comes with some tradeoffs that a minority of owners flag. The stock, while functional and adjustable, doesn't feel as solid as a traditional wood or heavier polymer stock. A few experienced shooters also note that at 5.8 lbs in .308 Win, muzzle rise is noticeable — some add a muzzle brake or suppressor via the threaded barrel to manage it.

Overall, discussions are positive. Owners who bought the 110 Ultralight specifically for pack-in hunting or long carries tend to be the most satisfied, since the rifle delivers on its core promise: meaningfully less weight without giving up real accuracy.
