180 Alpha Chassis



180 Alpha Chassis (Generation I Chassis) Savage shooters, KRG listened! When they couldn’t fit the Savage into the X Ray or Whiskey 3 Chassis, they went back to the drawing board and came up with a unique design that fits all of their design criteria.

Keeping with the theme of lightweight and ergonomic, the 180 Alpha, at 3.5lbs, is one of the very few chassis under 4lbs (one other being the X Ray). Despite the low weight, it keeps all the important ergonomic features as well as mounting options for slings, night vision mounts, and other accessories.

Like all of KRG chassis, it accepts AICS magazines (not included) right out of the box with no bottom metal purchase needed, and it has the tried and true V-bedding system cut into the aluminum backbone.

Fits: Savage SA (4.4″ spacing) side or bottom bolt release

Weight: 3.5 lbs
