MVP Disc Sports Neutron Reactor Disc Golf Midrange (170-175g / Colors May Vary) Review (2026)

What it is

The Reactor is one of MVP Disc Sports' core midrange discs, carrying flight numbers of speed 5, glide 5, turn -0.5, and fade 1.5, which places it in neutral-stable territory rather than firmly overstable or understable. MVP describes it as a versatile workhorse mid, built to give a neutral-stable GYRO push through the flight followed by a dependable fade at the end, which is the kind of predictable behavior players look for in a go-to midrange. This listing is the 170-175 gram version, near the top of the disc's weight range, and it comes in MVP's Neutron plastic, the company's most premium material offering.

Fit for the job

As a straight-flying, dependable-fade midrange, the Reactor fits well as an everyday disc for controlled shots, hyzer lines, and gentle turnovers, and MVP specifically markets it as useful for gap hitting and accuracy from both forehand and backhand. Lower-powered throwers get a flat-to-fade flight pattern that is easy to read and control, while more experienced players can use the slight turn to stretch out distance on flex shots. Where it is a weaker fit is in strong headwinds or for players who need a disc that holds a hard, predictable line no matter the conditions, since the -0.5 turn number means it is not as overstable as dedicated wind discs.

Features and specs

MVP lists the Reactor's flight numbers as speed 5, glide 5, turn -0.5, and fade 1.5, with a diameter of about 21.4 centimeters and a 13 millimeter rim width, dimensions consistent with a standard midrange disc. This listing covers the 170-175 gram weight range, close to the disc's maximum weight and generally preferred by players who want maximum stability and glide from the mold. The disc is beadless, meaning there is no ridge on the bottom rim, which tends to make for a smoother release and grip transition compared to beaded discs of similar speed.

Build and materials

This version uses MVP's Neutron plastic, described by the company as its most premium material, offering a distinctive look and feel while matching the strong durability of MVP's Proton blend. Neutron is available in a wide range of bright, opaque colors, and premium plastics like this typically hold their original flight numbers longer before beginning to turn over or lose overstability with wear, compared to a base-level plastic disc. That durability comes with a higher price point than MVP's entry-level plastics, which is standard across most manufacturers' premium plastic lines, but it means this particular Reactor should keep its neutral-stable flight consistent over more rounds before it needs replacing.

Value for money

For a premium-plastic midrange with genuinely versatile flight numbers, useful for straight shots, hyzers, and controlled turnovers alike, the Reactor in Neutron plastic is a solid pick for a player building out a bag with one reliable go-to mid rather than several specialized ones. The value is strongest for players who want a disc that will not need replacing for a long time thanks to Neutron's durability. It is a less efficient purchase for players who specifically need an overstable wind-fighting midrange, since the Reactor's mild turn number means a dedicated overstable mid will serve that specific role better.
