T-Bolt Straight-Pull Action
The defining feature of the T-Bolt is its straight-pull bolt system.
Unlike a traditional bolt-action rifle that requires lifting and rotating the bolt handle, the T-Bolt works by pulling the bolt directly rearward and pushing it forward.
Advantages:
✅ Faster follow-up shots
✅ Smooth cycling motion
✅ Less movement required between shots
✅ Excellent for small-game situations where quick shots may be needed
Browning describes the T-Bolt action as a straight-pull design intended for fast cycling while maintaining accuracy.
