SHS Spring Guide Extension Unit

SHS Spring Guide Extension Unit — a spacer that pre-loads the spring without changing it. Sold on its own. An extension unit sits behind the spring guide and takes up length, which pre-compresses the spring slightly and raises muzzle energy without buying a stiffer one. It is most useful where a spring sits just under the number you want, or on a short-stroked build where the standard spring no longer fills the space it used to. It is a tuning part rather than a repair one, and a small change goes a long way. Chronograph after fitting rather than assuming, because the step can be larger than expected. Specifications Specification Detail Part Spring guide extension unit Purpose Spring pre-load Manufacturer SHS Sold as Single unit Good to know before you buy How much length this adds, and which guides it suits, are both absent from the data we hold. No figure is being invented here, so treat it as an unquantified spacer and measure the result rather than predicting it. Frequently asked questions How much will it raise my muzzle energy? Our supplier gives no figure and the answer depends on your spring, cylinder and barrel. Chronograph before and after; do not assume. Will it fit my spring guide? Unstated by the supplier. Compare it against your guide before fitting, and ask us if you are unsure. Is this safer than fitting a heavier spring? It is a smaller step, which makes it easier to land on a site limit. It is not a way of avoiding a chronograph. ⚠ Chronograph after fitting, without exception: anything that changes spring pre-load changes muzzle energy, and a gun that goes over a site limit is coming home with you rather than onto the field. 💡 Titan Forge Airsoft tip: Test in small steps and write down what you did. Tuning by memory is how people end up over the limit without knowing why. Browse gearbox parts or message us.
