The Tracker 209 In-Line Muzzleloader comes with a 209 Primer Ignition System that allows you to get the hottest ignition possible. The one piece removable breech plug and built in 209 nipple makes take down for cleaning quick & easy. The adjustable Lite Optic Sight System allows you to see game during the most productive shooting hours. The Tracker's magnum receiver accepts a powder charge up to 150 grains (3-50 grain Pyrodex Pellets). A field breech plug/nipple wrench will take out the one piece breech system which is supplied with the Tracker 209.
