Specification

Serious power for long range builds

The SHS M170 is an extreme high torque spring for players building a genuine long range platform. As a guide it delivers around 550 to 560 FPS with a 0.20g BB, firmly into DMR and sniper territory, giving a big lift in FPS, joules and downrange impact for reaching out across the field.

Built for marksman and bolt action rifles

This rating is aimed at single shot marksman rifles, bolt action sniper builds and compatible high power AEG DMRs that need real punch. It is a specialist spring for a specialist role, not a general skirmish AEG upgrade.

Reinforce and tune to match

Power like this puts the whole drivetrain under load, so a reinforced gearbox, piston, spring guide and quality bushings or bearings, plus a suitable motor and battery, are strongly recommended. Fitting is best left to an experienced tech to keep the build reliable and safe.

Know your limits

High FPS guns are normally restricted to semi or bolt action with a minimum engagement distance, so always chronograph and follow your site’s rules. Let our airsoft gun repair service build it right, or browse more airsoft accessories.

Frequently asked questions

What FPS does the M170 make?

As a guide the M170 produces around 550 to 560 FPS with a 0.20g BB, which is DMR and sniper territory. Always chronograph your finished gun as exact output varies with your build.

Is this legal to use at a skirmish site?

At this power level the gun is normally restricted to semi automatic or bolt action with a minimum engagement distance, and full auto is not permitted. Always check and follow your site's FPS limits and MED rules.

What builds is the M170 for?

It is aimed at high power setups such as single shot marksman rifles and bolt action sniper rifles, plus compatible AEG DMR builds that need serious power.

Do I need to upgrade other parts?

Yes. At this power a reinforced gearbox, piston, spring guide, bushings or bearings and a suitable motor and battery are strongly advised to handle the load reliably.

Should a beginner fit this spring?

We recommend an experienced tech install a spring this powerful, because the gearbox needs proper reinforcement and tuning. Our Rochester technicians can build and chronograph it for you.
