NUPROL's latest offering into the Airsoft Market with newly designed 0.20g green and red illuminated tracer BBs, made to be more consistent and have better accuracy that ever before.

Produced by VORSK Airsoft, these Airsoft BBs are precision engineered 6mm BBs which are designed to be used in a wide range of Airsoft guns and replicas. These BBs are part of the VORSKs brand new range of Airsoft BBs ranging from light weight BBs for beginner Airsoft players, all the way up to super heavyweight BBs for professional players and snipers.

These particular BBs are BIO 0.43g BBs which are created from biodegradable materials so that they will gradually break down with time when exposed to natural environments. Touted as a more environmentally friendly BB, they are sometimes required by certain Airsoft sites to play. 

These 0.43g BBs are well within the bracket of Heavyweight BBs, and are ideally suited for Sniper Rifles and other high-power Airsoft Guns such as DMRs and Pistols (provided they have been suitably upgraded with an aftermarket HOP Bucking). If you need more poke from your replica and you have a HOP Bucking that can take it, then 0.43g BBs are a welcome 'upgrade' to your shooting experience.
