APO160FL Tube Rings

These rings fit my OTA perfectly with no play whatsoever, and the locking screws are knurled just right for a secure grip without tools. Exactly what I needed for a rock-solid mount setup.

The machining is flawless—the rings slide onto the dovetail plate without any binding at all. The screw threads feel precise and smooth, which gives me confidence this setup won't shift during a long imaging session.

Finally, tube rings that actually fit my scope perfectly without any shims needed. The precision machining is obvious as soon as you slide them on—solid, no wobble at all.
