Daystate Wolverine Service & Tuning

Professional in-house servicing and tuning for the Daystate Wolverine (non-regulated), carried out by our own technicians.

Booking required — please contact us before sending, posting or dropping off any rifle.

Choose your service

• Power Adjustment / Tuning — a tailored power tune to your pellet choice, with a full power report. Sub 12 ft lbs rifles are tested to ensure the muzzle energy will not exceed 12 ft lbs across multiple pellet weights.
• Full Service & Tuning — a complete strip, reseal and clean, plus the power tune above. Includes a full regulator rebuild using genuine Huma parts where a regulator is fitted.

Optional upgrade: Huma regulator fitment

This optional upgrade adds a mechanical regulator, which delivers physically stabilised air pressure to the firing valve. Benefits include:

• Tighter shot-to-shot consistency (lower ES / SD)
• More stable behaviour across the fill range
• Improved tune stability for precision shooting

This is a performance optimisation, not a correction — ideal for shooters chasing maximum consistency.

What's included in a full service

• Full O-ring replacement
• Internal clean, de-grease and re-grease
• Valve stem polish and new valve seat
• Barrel clean (on request)
• Leak test and power check

If we find any defective mechanical parts that need replacing, we will contact you first to discuss — this may incur additional cost. Please also tell us about any non-factory modifications made to the rifle's pressure-bearing parts.

What we need from you

• The pellets you shoot — for the most accurate tune
• Any muzzle device you use, and your single-shot tray or magazine

Turnaround

• Power Adjustment / Tuning — 3–8 working days
• Full Service & Tuning — 1–3 weeks

How it works

1. Contact us to book your service.
2. Get your rifle to us — see getting your rifle to us. Collection & return delivery can be arranged at extra cost.
3. We service, tune and prepare your full power report.
4. We return your rifle to you.

Note: we will do our best to get your rifle shooting through the same hole at 30 yds, but we cannot guarantee this every time due to natural variation between barrels.
