7mm AMASS bullets! These are the heavy duty bullets with antispark built into the male bullet end. A great way to set up your series connections for hi cell count/hi power electrics. Antispark saves your bullts from pitting out with the big spark on connection, and also increases the life of your ESC by soft charging the capacitors on initial connection.
Comes in a set of 4 bullets, 2 female with covers, 2 male with covers, one male is anti-spark.
