Punisher has designed these 5mm Low Profile Bullet Connectors with pure performance in mind. Each Bullet has a "Step" machined into them where the bullet relief joints are located. This keeps the bullet tighter as the plug/socket each wear from prolonged use. We also added a deeper recess (2.5mm) into the top solder saddle of these bullets to allow for better solder contact to the bullet, for a stronger connection, and exceptional amperage flow.
