NDK Stealth Micro 4mm Carbon Arrows — Built to Cut Wind and Drive Deep
Some shots come easy. A calm morning, a broadside bull, twenty yards.
Most don't.
Most of the shots that matter happen with a crosswind pushing your pin, an animal a little farther than you'd like, and a window that isn't going to stay open long. The bowhunter who chooses the Stealth Micro is the one who plans for those shots — because that's who this arrow was built for.
/// Let's Be Honest About What the Stealth Micro Is
The Stealth Micro is our 4mm micro diameter arrow — the technical precision instrument of our lineup.
What the Stealth Micro is, is a wind-cutting, deep-penetrating micro diameter arrow built for the bowhunter who takes shots in real conditions — open country, real wind, honest distance. Less surface area means less wind drift. A smaller diameter hole means less friction through hide and tissue. The physics don't care about marketing. Smaller diameter, same weight, deeper penetration. That's the whole story.
/// The 4mm Conversation — How It Stacks Up
The micro diameter category isn't new. Easton built the category with the Axis, and the Axis 4mm Long Range is the arrow most bowhunters think of when they hear "micro diameter." Victory's VAP line and Gold Tip's Pierce carved out their own followings for the same reason — serious western hunters figured out that skinny arrows buck wind and punch deeper, and they never went back.
So let's put the Stealth Micro in that company honestly, because that's the company it keeps.
Wind Drift
This is the reason micro diameter arrows exist. A 4mm shaft presents roughly 20% less surface area to a crosswind than a standard 5mm shaft. At 60+ yards in a 10 mph wind, that's the difference between a double-lung hit and an educated animal. Every premium 4mm on the market delivers this advantage — the Stealth Micro included. Physics doesn't play favorites between brands.
Penetration
A smaller diameter shaft follows the broadhead through the wound channel with less friction and less drag. Combined with the Stealth Micro's high front-of-center builds — more on the insert systems below — you get the deep, reliable penetration that made hunters fall in love with this category in the first place. Elk shoulders, quartering angles, heavy bone. This is what the platform was made for.
Durability — Where We Separate
Here's where we'll plant a flag: the Stealth Micro is ultra durable with the right set up. Backcountry hunting abuses arrows — rock impacts, pass-throughs into dirt, quiver rattle on a ten-mile pack-in. We built the Stealth Micro's carbon layup to take that abuse and keep flying straight. Micro diameter shouldn't mean fragile, and in the Stealth Micro it doesn't.
Price — Where It Isn't Close
A 6-pack of industry leading arrows will run you meaningfully more at retail than a Stealth Micro build — because those arrows pass through distributors and pro shop markups before they reach your hands. The Stealth Micro comes direct from us. Same category, same performance class, no retail markup standing between you and your next adventure.
The honest bottom line: the Stealth Micro can do anything the industry-leading 4mm arrows can do — cut wind, drive deep, and hold tight groups at distance — with durability we'll put up against any of them, at a direct-to-consumer price none of them can touch.
/// Who the Stealth Micro Is Built For
The Open Country Hunter: Antelope in the wind. Mule deer across a canyon. If your shots happen where the wind never stops blowing, the Stealth Micro's reduced drift is a genuine, measurable advantage — not a marketing line.
The Long-Range Practitioner: You practice at 80 so 50 feels routine. At extended distance, wind drift and trajectory consistency compound with every yard. The 4mm platform was built for exactly this discipline.
The Penetration-Obsessed Elk Hunter: High FOC insert options and a micro diameter shaft that follows the broadhead through with minimal friction. If your standard is "two holes, every time," this is your arrow.
The Gear Nerd Who Tunes: Fair warning — 4mm arrows demand more precise tuning than standard diameter shafts. If you enjoy dialing a bow to perfection, the Stealth Micro rewards the effort with flight quality standard shafts can't match. If you want forgiving simplicity, the Obsidian may be your better home.
/// The Specs
| Spine | GPI | Outer Diameter | Draw Weight |
|---|---|---|---|
| 300 | 9.5 | .241" | 60–70 lbs |
| 350 | 8.3 | .234" | 55–65 lbs |
| 400 | 7.9 | .230" | 45–55 lbs |
All Stealth Micro cut & fletched arrows come with 2.5" NDK Shield Vanes. Bare shafts available if you prefer to fletch your own.
/// Choosing the Right Spine
- Shooting 60–70 lbs? The 300 spine at 9.5 GPI is the workhorse — the stiffest, heaviest Stealth Micro and the right call for heavy broadheads and elk-class game.
- Shooting 55–65 lbs? The 350 balances weight and speed for most western setups.
- Shooting 45–55 lbs? The 400 gets you into micro diameter performance without needing a heavy draw.
When in doubt, go stiffer — especially on a 4mm platform where tuning precision matters. Not sure where you land? Reach out at Tylor@ndkarchery.com — we'll help you dial it in.
/// The Insert Systems — Where the Stealth Micro Gets Serious
Micro diameter arrows live and die by their component systems, and this is where the Stealth Micro build options genuinely separate from the pack.
CMI 75gr Half-Out
A precision CNC-machined 75gr half-out from CMI Archery — machined in Missoula, Montana to tolerances that mass-produced inserts can't hold. For the shooter dialing in a specific FOC or running a heavier point up front, this is component quality you can measure.
CMI HIT Insert & Collar
The premium build. Hidden Insert Technology seats the insert fully inside the shaft for a seamless, low-profile fit, while the machined collar locks the system in place and armors the shaft face against hard impacts. This is the most structurally sound front-end you can put on a micro diameter arrow — the same class of component system that hunters pay premium prices to add to competitor shafts. On the Stealth Micro, it's a build option straight from the shop. Add 5/8" to your carbon-to-carbon length to account for the collar.
Why CMI matters: NDK is an authorized CMI Archery dealer, which means genuine CNC-machined stainless components installed correctly before your arrows ever ship — not an aftermarket experiment on your kitchen table.
/// What Comes in the Box
- 6 Stealth Micro 4mm carbon shafts, cut to your specified length
- Your choice of insert system installed — Standard Half-Out with Sleeve, CMI 75gr Half-Out, or CMI HIT Insert & Collar
- 2.5" NDK Shield Vanes on fletched options
- Nocks installed
Everything you need to hunt. Nothing you don't.
/// How Does It Compare to the Rest of the NDK Lineup?
If you want maximum mass and bone-breaking momentum in a standard 5mm diameter, the Obsidian is the hammer. If flat-shooting speed is your priority, the Ghost flies faster. If you're getting started or building on a budget, the Series I is your foundation.
But if your hunts happen in wind, at distance, and against animals that demand every inch of penetration you can generate — the Stealth Micro is the most technically capable arrow NDK builds.
The NDK Stealth Micro is available in 6-packs starting at $89.99 — with premium CMI component builds available.
