Adjust length of pull only after eye relief is set. If the stock still feels short or cramped, use the Tikka Fit Checklist to confirm whether length of pull, cheek height, or scope position is the real issue before choosing spacers.
Length of pull is the distance from the trigger face to the centre of the recoil pad. It changes how the rifle lands in your shoulder, how naturally your trigger hand sits, and where your head ends up behind the scope.
The important part is order. A stock can feel too short if the scope is too far forward. It can feel too long if you are reaching for eye relief. Set optic position first, then check stock length.
Start with eye relief
Before adding spacers, mount the rifle with the actual scope, rings, rail, clothing, and position you use. Shoulder the unloaded rifle naturally and check whether the sight picture appears without stretching your neck forward or pulling back from the stock.
If eye relief is wrong, fix that before changing stock length. Length-of-pull decisions made before eye relief are easy to misread.
Signs the stock may be short
- You feel cramped behind the trigger after eye relief is set.
- Your trigger finger wraps too far around the trigger.
- The recoil pad lands awkwardly high or inside the shoulder pocket.
- Thicker hunting clothing makes the rifle feel noticeably shorter.
If those symptoms are present after the scope is positioned correctly, the Nokka LOP Spacer Kit is the length-of-pull path for compatible Tikka factory-stock setups.
Signs the stock may already be long
- You reach for the trigger instead of landing on it naturally.
- You struggle to keep the recoil pad settled in the shoulder pocket.
- You have to pull your head back from the scope to get a full sight picture.
If the rifle already feels long, do not add spacers yet. Recheck eye relief, cheek height, and shooting position first.
Spacer choices
The standard Nokka kit is built around an adapter plate, a 10 mm spacer, and a 20 mm spacer. As supplied, choose either +10 mm or +20 mm. The separate Flat-Recoil LOP Spacer is available in 10 mm, 20 mm, or 30 mm sizes when pad angle or shoulder contact is also part of the fit issue. For every LOP spacer, use one spacer by default. Stacking any combination of LOP spacers can be done only in special cases, but a multi-piece stack does not create the strongest possible connection and is not our recommended default. If stacking is required, glue the spacer pieces together before final installation and use only the confirmed locating and fastening hardware for the setup. Contact us first if the stacked setup and hardware have not already been confirmed. See how stock fit changes recoil feel for the fit-first explanation.
Choose the smallest change that solves the fit problem. If you are unsure between two settings, test the mount and sight picture from the position you use most often rather than choosing by height alone.
Use the hardware supplied for the confirmed setup. Glue is required between spacer pieces only when a special-case multi-piece stack is used; it does not replace the correct locating and fastening hardware. Stop and contact Nokka if the pad does not align or tighten securely.
Length-of-pull adjustment order
- Confirm the rifle is unloaded and set eye relief with the actual scope and rings fitted.
- Mount the rifle naturally and decide whether the stock still feels short, long, or neutral.
- If the stock is short, choose the smallest spacer change that solves the fit problem.
- Re-check cheek height after changing stock length.
- Confirm the sight picture again from the position you use most often before final zero.
Cheek height changes the result
Length of pull and cheek height interact. If your head is floating above the stock, you may misread the stock as too short or too long. If the checklist points to both stock length and cheek height, the Performance Kit combines the LOP Spacer Kit and Drop Comb Cheek Riser for compatible setups.
If only length of pull is the issue, choose the single LOP kit. If only cheek height is the issue, choose the riser. The checklist is there to keep that decision tidy.
After changing length of pull
After any stock-length change, re-check eye relief and cheek position before final zero. Moving the recoil pad changes where your shoulder, head, and trigger hand settle.
For the full setup sequence, see the Tikka precision setup guide.
Use the checklist to decide whether stock length, cheek height, or eye relief should come first.
Run the Tikka Fit ChecklistFrequently asked questions
What length of pull does a Tikka T3x have?
Many factory T3x sporter stocks are around 13.4 inches, while compact variants are shorter. Check your exact stock and measure trigger face to recoil-pad centre before deciding.
Should tall shooters always add spacers?
No. Add length only if the rifle still feels short after eye relief and scope position are correct.
Should I set cheek height before length of pull?
Set eye relief first, then check length of pull and cheek height together. If both are wrong, solve them as a system.
Can I use length-of-pull spacers with a cheek riser?
Yes, if both fit issues are present on a compatible setup. Re-check eye relief after changing either stock length or cheek height.
Which Nokka product should I choose if my Tikka feels short?
If eye relief is set and the stock still feels short or cramped, choose the LOP Spacer Kit. If cheek height is also low, choose the Performance Kit. If the stock already feels long, do not add spacers; run the checklist first.
