Maneuver quickly with a high quality AR pistol designed in the U.S.A by a veteran from the 82nd Airborne Division. TRIARC System's TSR-15S pistol includes a 8.3 inch barrel with an SBA3 brace to give you extra control without requiring a $200 NFA tax stamp.

While rugged enough for combat, the TSR-15S is refined enough for sub MOA accuracy with match grade ammunition. That's because of the TRACK 2.0 barrel. The barrel's "Single Edge Polygonal" combines the best of standard and polygonal rifling. The hybrid rifling allows the bullet to travel more accurately by reducing its deformation in the barrel.

  • Chambered in 300 Blackout
  • 8.3" Track 2.0 Barrel
  • NP3 coated barrel extension
  • Mil-Spec Nitride BCG with Enhanced 5 coil extractor spring
  • Triarc Enhanced Mil-Spec trigger
  • 7" Trilok M-LOK free float handguard
  • Low Profile pinned gas block
  • Raptor LT ambi charging handle
  • SB Tactical SBA3 pistol arm brace
  • Sprinco enhanced buffer spring
  • Mil-Spec 90 degree safety selector
  • A2 flash hider

The pistol is built to exceed Mil-spec standards. The a forged serialized upper and matching lower receiver are hand fitted as part of an elaborate quality control system at TRIARC. This rifle comes with a beautiful black anodized finish for enhanced durability. 

TRIARC Systems was founded by an Iraq war veteran Chris Reeves, a paratrooper who earned the Purple Heart. Now, he develops firearms for responsible civilians from his headquarters in Mansfield, Texas. When quality, durability and reliability are of the utmost importance, consider investing in a TSR-15S.
