This alternative ram for the Ontos blaster reduced the amount of misfeeds and misfires from using magazines with stronger springs like the Nerf Pro Stryfe X magazines and drum spring based magazines. The original ram would pinch darts that were seated too high and cause misfires. This ram allows improperly seated darts to funnel into the breech without catching on the ram.
Prints using the same settings as the original.
