Am I Legal? ASA, NFAA, IBO & USA Archery Equipment Rules Checker

Twelve inches for the front stabilizer, measured from the tip of the stabilizer (or the full quick-disconnect/enhancer/weight system, if you're running one) to the point where it attaches to the front of the riser. A single rear stabilizer is allowed separately, also capped at 12 inches including any weights, regardless of where on the bow it mounts. Both limits are hard caps under ASA's official Pro/Am rules — go a quarter-inch over on inspection and you're moved to an Open class for that shoot, not just warned.

No, across every organization's Bowhunter-style division. NFAA's Shooting Styles & Equipment Rules cap Bowhunter Freestyle (BHFS) and Bowhunter (BH) at five fixed reference points and explicitly ban scopes and clickers; a peep with or without a lens is fine, but it can't move once the round starts. IBO's rulebook bans magnification outright in Hunter Class, though its Advanced Hunter Class (AHC) is the one exception — it uses the same fixed-pin housing but allows a lens with no magnification restriction, which is worth knowing if a lens is the only thing keeping your setup out of base Hunter Class. ASA's Hunter Class rules follow the same no-lens rule, though a clarifier or verifier disc inside the peep itself doesn't count as magnification in any of these rulebooks.

World Archery caps every division — Recurve and Barebow alike — at 9.3mm, which is 23/64 of an inch; that number comes straight from Book 3 of the World Archery rulebook and is the figure USA Archery uses for its Olympic-style events. The Vegas Shoot and standard NFAA Freestyle/Open divisions are considerably more permissive: the shaft cap there is 0.422 inches (27/64), with the point diameter allowed up to 0.425 inches. In practice that means a "fat shaft" built for line-cutting in 3D or indoor spots is comfortably legal at a Vegas-style event and just as comfortably illegal at a USA Archery target event.

ASA chronographs every bow at check-in against a class-specific FPS ceiling — 290 FPS for the men's Open and Known Pro divisions, lower for some women's and youth classes. ASA's rulebook adds a three percent margin of error, rounded up to the nearest whole number, to account for normal variance between chronograph units; that's roughly 299 FPS on a 290 cap. That margin exists to protect archers from a slightly-hot chronograph reading, not as extra headroom to tune toward — if your true arrow speed is over the class limit, dropping draw weight or draw length, or moving to a heavier arrow, is the fix, not hoping the on-site unit reads generously.

Any kind of sight. World Archery's Barebow rule is explicit that the bow must be "free from any sights, marks or blemishes that may be used as a sighting aid," and separately bans clickers, draw checks and levels entirely. Stabilizer weight is allowed only on the lower half of the riser, and the whole unstrung bow, weights included, has to physically pass through a 12.2cm ring — which in practice rules out anything resembling a long-rod front stabilizer, since a rod that long won't fit through the ring. NFAA's Barebow styles are similarly strict on sights but do permit a single straight stabilizer up to 12 inches for the compound version of the class. String walking is explicitly allowed under World Archery Barebow, which surprises a lot of archers coming from a sighted discipline.

Freestyle is the open equipment division: any sight configuration, including a scoped, magnified sight housing, and no stated stabilizer length limit as long as a rear bar doesn't touch your body. Bowhunter Freestyle exists specifically to cap that equipment back down toward field conditions — five fixed reference points maximum, no scope, no clicker, and one straight stabilizer (coupling device included) capped at 12 inches. Full definitions for both styles are in NFAA's Shooting Styles & Equipment Rules. The two styles also shoot from different stakes/yardages at most NFAA events, so a setup that's dialed in for Freestyle almost never carries over to BHFS without physically swapping the sight and shortening the stabilizer.

Measure the entire installed assembly, not just the visible carbon rod. ASA's own wording for Hunter Class is "from the tip of the stabilizer/system to the point of attachment on the front of the riser" — meaning a quick-disconnect, vibration dampener, or end weight all count toward the 12-inch total, even though they're separate parts. IBO's rulebook measures "from each point of attachment," which matters if your stabilizer mounts at an offset rather than dead center. When a setup is genuinely close to a limit, measure it the way the strictest applicable rule reads, with everything attached, rather than measuring just the rod and assuming the hardware is free — that's the single most common way archers get bumped to a more open class at check-in.
