Vorsk Bio Tracer Airsoft BBs

Vorsk is Nuprol's dedicated airsoft pistol and BB brand — the same company behind the RZR range but with Vorsk BBs developed specifically to complement the tolerances of the Vorsk pistol line and performance AEG market. Manufactured to a consistent 5.95mm diameter with a polished, seam-free surface, Vorsk BBs are designed to feed reliably and engage the hop-up consistently across the full weight range.

How tracer BBs work

Phosphorescent coating on the BB absorbs UV light from a tracer unit at the muzzle. As each BB passes through the unit before leaving the barrel, it receives a brief UV charge that causes it to glow in flight — a visible streak of light with every shot. Ideal for night games and low-light play.

A tracer unit must be fitted to your rifle for the BBs to glow. Without a tracer unit they perform identically to standard BBs.

Certified biodegradable polymer that breaks down naturally outdoors — identical 5.95mm diameter and surface quality to the standard range. No performance penalty. Running bio as your default for all outdoor play means you're always site-compliant, and it's the right choice for the environment.

The Bio Tracer range is for a specific scenario: a night game at an outdoor site with a bio requirement. Standard tracers are not biodegradable. Standard bio BBs don't glow. The Vorsk Bio Tracer covers both. Available in 0.20g, 0.25g, 0.28g, and 0.30g across 1,100R bottles, 2,000R bottles, 3,600R bottles, and 1kg bags — check the SKU table for which combinations are available at each weight.

All Vorsk Bio Tracers glow green. Tracer unit required.
