SHS M110 Main Spring - The Ultimate Power Upgrade for UK Woodland Domination

When "standard" just isn't enough - the SHS M110 is the go-to choice for players looking to push their AEG right up to the typical UK site limits. Designed for maximum efficiency and durability - this spring provides that extra bit of "oomph" needed to reach out across long distances in dense British woodland. If you are tired of your BBs dropping short of the target - the M110 delivers a significantly flatter trajectory and harder-hitting performance without compromising the longevity of your gearbox.

Key Features and Performance

• Premium High-Grade Steel - Cold-drawn and stress-relieved to maintain its power rating even after thousands of cycles.
• Non-Linear Coil Design - Features varying tension zones to reduce "gearbox slap" and protect your motor during the initial take-up.
• Heat-Treated Coating - A specialized finish that reduces internal friction and heat build-up within the piston assembly.
• Consistent Power Delivery - Engineered to provide a stable Joule output - ensuring your hop-up can lift heavier weight BBs with ease.
• Precision Ground Ends - Both ends are flattened to ensure the spring sits perfectly flush against the spring guide and piston head.

The "Pro" Take

The SHS M110 is the "secret weapon" for any tech building a dedicated outdoor rifle. While cheaper springs can be "crunchy" or lose their tension after a single game day - the SHS steel remains remarkably resilient. Because it is a non-linear spring - it actually feels snappier than many linear M100s - giving you a faster semi-auto reset. It is the perfect partner for a high-torque motor and a quality 11.1v LiPo battery - creating a build that is as responsive as it is powerful.

UK Spec and Site Performance

In the UK - navigating the "350 FPS" rule can be tricky. On many builds with a perfect air seal - an M110 can actually push you slightly over the 1.13 Joule limit (approx. 350 FPS with 0.20g). However - for the majority of standard AEGs with a 250mm to 360mm barrel - the M110 is the "Woodland King" - typically settling at around 340-355 FPS.

This is the ideal choice for sites like "Eversley" or "Longmoor" - where you need to punch through light foliage and maintain velocity over open ground. If you find your rifle is shooting a bit low with an M100 (around 310 FPS) - dropping in an M110 is the most reliable way to get closer to that 1.14 Joule UKARA limit. Just remember to always "bed in" the spring with a few hundred shots before heading to the chrono - as new springs can sometimes start a little "hot" before settling into their permanent UK-legal range.

Friendly FAQ

Will this make my gun shoot over the 350 FPS limit?
It depends on your air seal! In a very high-efficiency build - an M110 can hit 360+ FPS. Always test your rifle with a chronograph after installation to ensure you stay site-legal.

Do I need a better motor for this spring?
While a standard motor can pull an M110 - we highly recommend a High-Torque motor to keep your trigger response snappy and prevent your battery from getting too warm.

Is this spring compatible with "Quick Change" gearboxes?
Yes! The M110 fits all standard AEG "Quick Change" systems - making it easy to swap out if you find yourself at a CQB site with lower limits.

Should I use heavier BBs with this spring?
Absolutely. To get the most out of an M110 - we recommend 0.25g or 0.28g BBs. They will be more stable in the wind and take better advantage of the increased power.
