Red Dragon was founded in 1975 in Bridgend by two former Ford engineers, and the company went on to become the first to mass-produce precision tungsten darts in 1978. The Flightmaster Sidewinder sits in the brand’s long-running Flightmaster range, an entry-to-mid tier line built around 80% tungsten barrels rather than a player-signature design.
It has built up one of the larger review samples of any dart on this site, which makes it a useful case study in what a widely-owned budget tungsten set actually delivers. We haven’t thrown these ourselves, so instead of a hands-on verdict you’ll find the published specs and a round-up of what owners make of them.

How They’ve Been Received
Across both samples the pattern holds: buyers consistently rate the value highly for an 80% tungsten set, and the square-groove grip gets picked out as secure without feeling aggressive. Red Dragon’s own review breakdown scores the set at 4.6 out of 5 for quality and 4.9 for value, with grip a little further back at 3.7, suggesting the texture divides opinion more than the build quality does.
What Reviewers Say
One verified buyer, still working out which weight suited them, picked out the grip and looks as the highlights:
“Really like these darts, got them in a 23g weight as I'm still experimenting with different wights and style. Nice grip and look good too.”
What owners consistently praise
- Strong value for an 80% tungsten barrel, rated close to the top of the scale by buyers
- Square-groove grip feels secure without being harsh, according to most owners
- Four weights (23g to 30g) cover a wide range of throwing styles
- Large review sample gives more confidence than most budget darts get
Common criticisms
- Grip is the one category that scores noticeably lower than the rest in Red Dragon's own breakdown
- Only one set of flights and shafts included, so a spare set is worth budgeting for
- 80% tungsten means a slightly thicker barrel than a 90% set at the same weight
The Grip: What to Expect
Red Dragon rates the Sidewinder’s grip at 3 out of 5 on its own scale, square grooves running the full length of the barrel. That is a deliberately middle-ground design, more texture than a smooth barrel but well short of the aggressive knurling found on some premium sets.
Owner feedback broadly agrees with that positioning. Most describe the grip as comfortable and secure for extended sessions, though Red Dragon’s own review data shows grip as the lowest-scoring category of the set (3.7 out of 5, against 4.6 for quality and 4.9 for value), which points to a genuine split: some players want more bite than a level 3 grip gives them.
Who They Suit
The Sidewinder suits players who want a genuine 80% tungsten barrel across a wide weight range without paying for a signature name or a premium grip pattern. The four-weight spread, from 23g up to 30g, covers most throwing styles, and the value scores are among the strongest on this site.
Players who want a noticeably higher tungsten percentage in a similar price bracket should compare it against Red Dragon’s own Amberjack 14, which sits at a slightly higher price for a 90% barrel. Anyone who finds the square-groove grip too gentle should look for a set with a more aggressive knurled or ringed texture instead.
The Consensus
Owners rate the Sidewinder as a genuinely good value 80% tungsten dart, and the sample size behind that verdict is larger than almost anything else reviewed on this site. The square-groove grip is the one point of disagreement: most find it comfortable, but Red Dragon’s own data shows it as the weakest-scoring aspect of an otherwise strongly-rated set.
For a budget-to-mid tungsten dart without a player’s name attached, the reception says it does the basics well and does not overreach on price.
How we compile this page
We don’t throw every dart ourselves. Instead we gather the manufacturer’s published specifications and weigh up the reception from owners and independent reviewers, then flag where they disagree so you can make up your own mind. Where a headline rating comes from manufacturer-hosted reviews, we say so, because those tend to skew positive.
