Due to the ongoing tariffs, we're ordering these in limited batches.

The Zius BK1s is a lightweight Automatic Electric Blaster (AEB). Featuring the same logic board as the BK2s, but with a longer barrel, this blaster is capable of slightly higher average FPS. Available in bright yellow.

We initially carried the BK2s, but the factory has since simplified production to offer only the BK1s.

*NOTE: The recommended age for this blaster is for adults 18+. Teens 14+ may only use this blaster with appropriate adult supervision. Use the BK1s AEB at your own risk.
