Bipod Harris Style with S Lock

A Harris style bipod with S lock is a rifle rest that allows for a side-to-side swivel to level the rifle on uneven terrain, and the S lock is a user-installed lever that replaces the standard tension knob, providing easier and more precise control over the swivel function. This upgrade improves upon the factory knob, which can be difficult to adjust, by using a lever that offers greater torque and leverage for fine-tuning the tension.
Features and benefits
Easier tension adjustment: The primary benefit is the ability to adjust the tilt tension with the S lock lever instead of a small knob, which can be difficult to grasp and turn, especially in the field.
Quick and fine adjustments: The lever allows for quick locking and unlocking of the swivel, as well as fine-tuning of the tension while the shooter is in position.
Improved ergonomics: The lever provides better leverage for tightening or loosening the pivot lock.
Durability: Many aftermarket S lock levers are made from strong materials like reinforced nylon and stainless steel, which can be more robust than the original knob.
Protection: Some S lock designs include a dust shield or spacer to help protect the internal mechanism from dirt and debris.
Easy installation: The S lock typically replaces the factory tension knob by simply unscrewing the original knob and attaching the new lever, often with no special tools required beyond a basic screwdriver.
How it works
The standard Harris S series bipod is designed with a swivel or cant function to level the rifle on uneven ground, controlled by a tensioning knob.
The S lock is an aftermarket replacement for this knob.
To install, you typically remove the original knob and then attach the S lock lever to the same pivot post.
The lever has a pulling-out function, allowing it to be repositioned to a desired angle before being pulled up or down to engage the ratchet mechanism for tightening.
The lever allows the user to apply more force to tighten the lock or to loosen it for adjustments.
