Quick Answer: The best soft tip darts for most buyers in 2026 are the Viper Astro 80% Tungsten set (16-18g, about $58-62) — a slim tungsten barrel with a travel case and spare parts included. Want the thinnest barrel money can buy at a legal electronic-board weight? The Unicorn Purist Evolution Phase 3 (18g, 90% tungsten, about $63-73) gets you there for under $75. Whatever you pick, stay under 20 grams total weight — Escalade Sports, the parent company behind Viper, Fat Cat, and Arachnid boards, states in its own manuals that heavier darts void the warranty.
Buying the right dartboard is only half the setup — we covered electronic dart boards already. The darts themselves are where most first-time buyers overpay or, worse, buy a set that’s technically too heavy for the board they already own. Soft tip darts look like smaller, lighter steel tip darts, but the weight ceiling, the 2BA tip thread, and the tungsten-percentage math all work the same way — just inside a much tighter gram window.
Soft tip darts by the numbers:
- 20 grams is the hard ceiling on most cabinet electronic dartboards. Per Escalade Sports’ own product manuals — the parent company behind Viper, Fat Cat, and Arachnid, the three brands behind every board in our best electronic dart board roundup — darts over 20 grams “will damage the electronic board and automatically void the warranty.”
- That ceiling has moved before, and it isn’t universal. Arachnid-brand coin-op machines raised their own limit to 20 grams back in 2016 after years at a lower cap, and Darts Live cabinets allow soft tip darts up to 25 grams — per CyberDarts’ steel-vs-soft darts reference guide. Don’t assume one board’s limit applies to another.
- Most retail soft tip sets land between 16 and 19 grams full weight specifically to stay well clear of that 20g line, leaving a buyer margin even after swapping in a slightly heavier shaft or flight.
- 80% tungsten is the practical sweet spot, the same logic as steel tip darts: tungsten is dense enough to keep a barrel slim at a legal weight, while nickel-silver or brass barrels have to bulk up to hit the same gram target — the real, non-marketing reason cheaper sets group worse.

1. Viper Astro 80% Tungsten — Best Overall
Viper Astro 80% Tungsten Soft Tip Darts
- 80% tungsten barrels in a slim profile, sold in both 16g and 18g — comfortably under the 20g electronic-board ceiling.
- Ships with a storage/travel case plus a spare set of flights, nylon shafts, tips, and a dart wrench.
- From Escalade Sports' own Viper brand, the same lineup behind the Viper 800 and Viper Neptune boards in our electronic dartboard picks.

The Astro wins this list because it solves the two problems a first-time soft tip buyer actually has: staying under the board’s weight limit and surviving the first snapped tip. At 16-18 grams it leaves real margin below the 20g ceiling most cabinet boards enforce, and the included spares mean a cracked shaft mid-game doesn’t end the night. Pricing varies noticeably by retailer and weight variant — we saw it from about $58 at a specialty dart retailer up to $79 at a sporting-goods chain for a 3-pack bundle — so it’s worth a quick price check across sellers rather than buying the first listing you find.
2. Fat Cat Bulletz — Best Budget
Fat Cat Bulletz Soft Tip Darts
- 90% tungsten per retailer listings, at a price usually reserved for 80% sets elsewhere on this list.
- Ships with a storage/travel box plus extra flights, nylon shafts, and a dart wrench.
- From GLD Products, the same Escalade Sports division behind the Fat Cat Mercury board in our electronic dartboard picks — same brand family as the Viper Astro above.
The Bulletz name covers both a steel tip and a soft tip line — double-check you’re buying the soft tip version, since the two look nearly identical in listing photos. At roughly $47 for a 90% tungsten barrel, it undercuts every other tungsten set on this page on price while still landing well under the 20g weight ceiling. The trade-off versus the Astro above is fewer included spares, so budget a separate flights/shafts purchase sooner.
3. Unicorn Core Tungsten Style 2 — Best Value
Unicorn Core Tungsten Style 2 Soft Tip Darts
- 80% tungsten barrel with standard 2BA tip threading, the same thread standard used across every brand on this list.
- 18-gram full weight, squarely inside the retail-standard 16-19g soft tip window.
- From Unicorn, a UK dart brand with a wide catalog of soft tip barrels across multiple tungsten tiers.
Unicorn’s Core Tungsten line is the honest middle rung here — not the cheapest, not the thinnest barrel, just a straightforward 80% tungsten set at a fair price. It’s worth knowing that Unicorn also sells a Core Tungsten variant closer to 60% tungsten blended with nickel alloy at a similar-looking name and price, so check the specific listing’s tungsten percentage before buying rather than assuming every “Core Tungsten” product is the same barrel.
4. Unicorn Purist Evolution Phase 3 — Best Premium Tungsten
Unicorn Purist Evolution Phase 3 Soft Tip Darts
- 90% tungsten — the same top-tier density most steel tip buyers pay $60+ for, here at an 18g electronic-legal weight.
- 2BA tip threading, compatible with standard replacement soft tips from any brand.
- Priced well under the tour-level signature barrels at the top of this category.
If the only thing you want from a soft tip set is the thinnest barrel a legal weight allows, this is it. 90% tungsten at 18 grams means a genuinely slim profile with real margin under the 20g board ceiling — the same math that makes 90% tungsten the top recommendation on our steel tip darts page, just scaled down to soft tip weights. It costs more than the Core Tungsten Style 2 above, but less than half of the signature tour barrel at the bottom of this list for nearly the same barrel thinness.
5. Target Prime Xeno — Best Tour-Level
Target Prime Series Xeno Soft Tip Darts
- A signature barrel from Target Darts' Prime Series, released alongside a professional player endorsement.
- 19g tungsten barrel weight, but 21 grams full weight once shafts, flights, and tip are assembled.
- Priced at specialty dart retailers near $150 — single-retailer pricing, confirm current cost before buying.
This is the one pick on this page worth a direct warning: the Xeno’s 21-gram full weight sits above the 20-gram ceiling that Escalade Sports enforces across the Viper, Fat Cat, and Arachnid boards recommended elsewhere on this site. That doesn’t mean it’s unusable everywhere — Darts Live cabinets accept soft tip darts up to 25 grams — but if you own a Viper 800, Fat Cat Mercury, or Arachnid Cricket Pro 800 from our electronic dartboard picks, this specific barrel is the wrong buy. Check your own board’s printed weight limit before spending $150 on a tour-level barrel, not after.
How to choose soft tip darts
- Check your board’s weight limit before you check tungsten percentage. Most cabinet boards cap at 20 grams total — Escalade Sports states this plainly for the Viper/Fat Cat/Arachnid boards most buyers already own — and exceeding it voids the warranty outright, not just hurts performance.
- 80% tungsten is the default; 90% is the upgrade. The same density logic as steel tip darts applies here, just at a lighter overall weight.
- Confirm 2BA threading before buying replacement tips or shafts separately — it’s the standard across every brand here, but always worth a label check.
- Buy spare flights and shafts the same day. See our best dart flights and best dart shafts picks — soft tip parts snap just as often as steel tip parts.
- Don’t assume a bigger price tag means a safer weight. The most expensive set on this page is also the only one over the standard 20g ceiling — price and board compatibility are two separate questions.
The bottom line
The Viper Astro 80% Tungsten (16-18g, about $58-62) is the best soft tip darts set for most buyers in 2026 — a slim tungsten barrel with a travel case and genuine spare parts included, comfortably under the 20-gram weight ceiling most electronic boards enforce. On a tighter budget, the Fat Cat Bulletz (18g, 90% tungsten, about $47) undercuts it on price without giving up tungsten density, and the Unicorn Core Tungsten Style 2 (18g, 80% tungsten, about $47-56) is the honest middle option. Want the thinnest barrel a legal weight allows, the Unicorn Purist Evolution Phase 3 (18g, 90% tungsten, about $63-73) gets you there for well under $75. Skip the Target Prime Xeno unless your board specifically allows darts over 20 grams — its 21-gram full weight exceeds the limit printed in Escalade’s own manuals for the Viper, Fat Cat, and Arachnid boards most buyers already own.
