NUPROL - RZR 0.20g Precision Tracer BB x3300 - Green are NUPROL's latest offering into the Airsoft Market with newly designed BBs made to be more accurate and consistent that ever before. The BBs are constructed from Polymer, and are 5.95mm in diameter, with a +/- 0.01mm Tolerance and will illuminate when fired through an Airsoft Tracer Unit. The BBs are sorted before bottling, only allowing BBs within 0.01mm in size difference to be used. These BBs are specifically built using a special colouring, which allows the BBs to absorb light and glow in the dark, allowing you to see the trajectory of your BBs even in dark environments when partnered with a Tracer Unit. NUPROL's latest BBs are slightly smaller than other brand BBs, which helps with Weapon Feeding and with Tightbore Barrelled Weapons. The BBs come in a newly designed bottle, featuring a square design allowing up to 3300 BBs to be contained within its more stable and tough design. This is the base weight of BBs, and are typically used for Chronoing weapons at Game sites, and are great for CQB and Indoor Environments. These BBs are perfect for any Airsoft Skirmisher looking for their next go-to brand of BB, and for those looking for a more reliable and consistent BB.
