30Mm Sidelok Modular Optic Mount

The Kinetic Development Group 30mm Sidelok Modular Optic Mount is a quick-detach scope mount built for shooters who demand versatility and reliability in the field. Its modular design lets you swap ring sizes without replacing the entire mount, making it an economical choice if you run multiple optics or plan to upgrade. The Sidelok works with any Picatinny rail and handles out-of-spec receivers with its cam-lock system—a practical feature when precision isn't guaranteed in the real world.

One-handed QD operation is the signature here: press the front release button and the mount comes free fast. The locking mechanism is engineered to resist accidental release, so you won't lose your zero on the move. The rings slide forward or backward along the mount body, letting you clear objective bells, turret knobs, or magnification collars without repositioning your whole setup. This flexibility is especially valuable on compact builds or when you're running a scope with a large bell or aggressive turret design.

CNC machining and wire-EDM cutting keep the rings as concentric as the manufacturing process allows. The top and bottom halves are machined as a single unit, then separated—a process that maintains alignment better than machining them apart. Witness marks printed on the rings help you match top and bottom halves correctly if you're working with multiple sets. Type 3 hardcoat anodize in matte black resists wear and delivers a professional finish that blends with tactical and hunting rifles alike.

Frequently Asked Questions

Will this 30mm mount fit my AR-15 or other Picatinny rail?

Yes. The Sidelok is designed for any Picatinny rail and includes a cam-lock system that accommodates out-of-spec rails, so it'll clamp securely even if your receiver rail isn't cut to the tightest tolerances.

Can I use this mount with different scope sizes?

The rings are removable, so you can swap them to fit a different tube diameter without buying a new mount. Witness marks on the rings help you keep track of which top half pairs with which bottom half if you're mixing and matching sets.

How do I detach the mount from my rifle?

Press the release button at the front of the mount with one hand. The cam-lock design is engineered to prevent accidental release under normal use, so you won't lose your zero unintentionally.

Can I reposition the rings to clear my scope's objective bell or turrets?

Yes. The rings slide forward and backward along the mount body, giving you room to work around large objectives, turret knobs, or magnification adjustment collars without repositioning the entire mount.
