Thompson Center® Triumph™ Bone Collector™ Muzzleloader - 8528

Thompson Center® Triumph™ Bone Collector™ Muzzleloader - 8528 - c From the styling of the stock to the advanced Weather Shield® corrosion resistant finish, the Triumph Bone Collector Series embodies the spirit of Michael Waddell and offers hunters a muzzleloader that is rugged, accurate and capable of handling magnum charges with ease. 

This Triumph Bone Collector has a composite stock in Realtree® AP® Camo. It features a FlexTech® stock and is equipped with four Energy Burners™ that have been placed at precise locations which allows the stock to compress slightly during recoil. This design is easy on the shooter’s shoulder and reduces felt recoil by 43 percent. 

The new Triumph Bone Collector Series features Thompson Center's patented Power Rod®, a solid aluminum ramrod with pivoting handle, and patent-pending Speed Breech® XT breech plug, which can be removed by hand for quick cleaning or unloading. The rifle comes complete with black traction grip panels on the forend, and camo Weather Shield receivers and camo barrels to lock out corrosive elements, along with a distinct Bone Collector logo on the grip cap. The Triumph muzzleloader features a 28” fluted barrel with the QLA® muzzle system to aid in accuracy and loading. The barrel also features adjustable Fiber Optic sights and is drilled and tapped for scope mounts.  

The Triumph Bone Collector™ is the most performance driven, innovative magnum muzzleloader on the market today. Wherever your adventure takes you, the Triumph Bone Collector™ will be there to help you take your next trophy.
