DESIGNED FOR THE ENTHUSIAST

Our Stiller pre-fit barrels are compatible with the Predator (short & long), Predator Sport, Tac 30, Tac 300, MK13, and Wombat actions. Pre-fits will fit all actions using the .187" thick recoil lug. You're barrel will arrive chambered and threaded for ease of installation - simply torque the barrel on, verify headspace, and you're ready to shoot!

Built for shot-for-shot accuracy, they deliver outstanding accuracy and performance, making them the perfect upgrade for Stiller action fans.

DISCLAIMER:
Every shouldered pre-fit is guaranteed for proper headspacing.
Please note that due to action variances, we cannot guarantee the barrel engraving's alignment with your stock line.
