Tikka ACE & UPR Length of Pull Kit — LOP Spacers for ACE / UPR
// Fitment & specsConfirm it fits before you buy
Engineered to Tikka's exact stock tolerances — not a universal part forced to fit.
Three steps, minimal tools
Remove the recoil pad
Back out the buttpad fasteners and lift the factory pad off.
Stack to your length
Combine the 5mm, 10mm and 20mm spacers for your LOP — anywhere from 5 to 35mm in 5mm steps.
Reattach the pad
Run the included extended fasteners through and snug the pad back down.
Common questions
Does this fit my Tikka ACE or UPR?+
Yes — it's designed for the Tikka T3x ACE (Target and Game), T3x UPR and T1x UPR buttstock mounting patterns, which differ from the standard T3x/T1x OEM stock. (For OEM sporter stocks, use our standard LOP Spacer Kit.)
How much length of pull can I add?+
Up to 35mm. The 5mm, 10mm and 20mm spacers stack in any combination — from 5mm to 35mm in 5mm steps.
Do I need a gunsmith to fit it?+
No. It bolts between the buttstock and recoil pad with the included extended fasteners — under five minutes with a screwdriver, fully reversible, no permanent modifications.
What's it made from?+
PETG, made in Australia — light, tough, and engineered to the ACE/UPR geometry rather than a universal part forced to fit.

The Tikka ACE and UPR are built for precision — but factory length of pull isn't built for you. Whether you're shooting stages in a PRS match or adapting your UPR between summer and winter kit, LOP needs to be dialed in.
The Nokka ACE/UPR LOP Spacer Kit gives you up to 35mm of adjustable length of pull on Tikka's premium platforms. The kit includes three stackable spacers — 5mm, 10mm and 20mm — designed specifically for the ACE chassis and UPR stock geometry — this isn't a universal spacer bodged to fit.

If you've invested in a Tikka ACE or UPR, you already know that fit matters. This is the fastest way to get your LOP right without replacing the stock. Install takes under 5 minutes with a screwdriver.
Already have the standard T3x/T1x kit? This is a different product — the ACE and UPR use a different buttstock geometry and mounting pattern.
