Steyr AUG Enhanced Trigger Spring Kit

The factory Steyr AUG trigger pull is heavy: roughly 9 pounds on a standard trigger pack and 12 pounds or more on some NATO packs. The trigger feel is also gritty due to the hammer-sear geometry and factory spring tension. The Steyr Enhanced Trigger Spring Kit is the cheapest meaningful trigger upgrade for the AUG and the first upgrade most owners install. The kit replaces the factory left and right hammer springs and the trigger spring with lighter Steyr OEM springs that reduce felt trigger pull by 2 to 3 pounds.

Construction is wire steel matching factory Steyr specifications. The kit is compatible with both Standard and NATO AUG trigger packs, so any AUG A3 or A3 M1 owner can use it regardless of stock pattern. Installation requires partial disassembly of the trigger pack, which is more involved than a drop-in trigger swap on an AR-15 but is well-documented in Steyr Arms USA's published instructions and in community videos.

The reduced spring tension does not change the two-stage trigger geometry or the long factory take-up; for shooters who want a match-grade trigger feel, combine the spring kit with the 20/20 Precision Trigger Sear Mod ($129) which addresses pre-travel and reset. For owners who just want the trigger to be less of a chore at the range, the spring kit alone takes the AUG from a 9-pound chore to a 6-7 pound trigger that is comfortable for extended sessions.
