Tikka ACE & UPR Length of Pull Kit — LOP Spacers for ACE / UPR
// Fitment & specsDetails before you buy
Key details on fit, setup and use before you buy.
Three simple steps
Remove the recoil pad
Back out the buttpad fasteners and lift the factory pad off.
Choose your length
Use one spacer by default. If a multi-piece stack is genuinely required, glue the spacer pieces together before final installation.
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 is designed for the Tikka T3x ACE Target, T3x ACE Game, T3x UPR and T1x UPR buttstock mounting pattern. For OEM sporter stocks, use the standard LOP Spacer Kit.
How much length of pull can I add?+
Up to 35 mm using the supplied 5 mm, 10 mm, and 20 mm spacers. 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.
Do I need a gunsmith to fit it?+
No. It bolts between the buttstock and recoil pad with the included extended fasteners — a quick screwdriver job with no permanent stock modification.
When does it ship?+
Yes. Available shipping options and any duties/taxes are shown in cart/checkout before payment.
Full details, specs & FAQ
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 spacers - 5mm, 10mm and 20mm - designed specifically for the ACE chassis and UPR stock geometry; this is not a universal spacer forced to fit.
Stacking rule for every LOP spacer: 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.

Already have the standard T3x/T1x kit? This is a different product — the ACE and UPR use a different buttstock geometry and mounting pattern.
