This kit includes 3 trigger springs with the option at checkout of selecting either 3x ultralight springs (all the same) or an ultralight, light and medium (1 of each). These springs replace the original Tikka T3 / T3x / T1x and Sako 75, 85, A7 trigger spring and achieve a range of pull weights starting at 1lb which are repeatable, safe and break cleanly every time.

Made from quality stainless steel wire and plated for easy identification and increased corrosion resistance. Lumley Arms' spring breaks cleanly and consistently at the listed pull weights* when installed correctly**. Further improvements are possible by polishing the internal trigger components with varying grits of rouge compounds on a sisal wheel / buff.

  • Ultralight ~1lb (gold color)
  • Light ~1.5lb (silver color)
  • Medium ~2lb (black color)

*Note: Results may vary slightly between individual rifles and trigger pull gauges. Lumley Arms Trigger Spring pull weight is measured using an RCBS gauge.

**Note: Lumley Arms supply replacement springs only. If unsure on installation, we highly recommend having a qualified and competent gunsmith do the job. Slight variations between different rifles may result in an unsafe trigger when fitting these springs. Always ensure the rifle is unloaded before commencing work and test trigger function extensively upon reassembly whilst rifle is unloaded. Slam closing the bolt and dropping the rifle onto the buttpad (both whilst unloaded) is recommended. Adjust the grub screw until a safe trigger is achieved.

Advantages of Lumley Arms Trigger Spring Kit:

  • Consistent trigger pull
