Accessories
The right adapter decides whether a clip-on works; the right mount decides whether a zero survives. Night Pearl accessories exist so the system holds together — adapters sized to your day scope's objective, rings and mounts built for thermal weight and recoil, and the batteries and spares that keep a season running. Same house, same standards as the optics they serve.
THE SYSTEM IS THE PRODUCT
Optics earn the praise — adapters, mounts and power make them work night after night.
Getting the fit right
Adapter sizing, the only measurement that matters
A clip-on is chosen by the outer diameter of your day scope's objective bell — not by the scope's brand, magnification or tube size. Measure the bell across its widest point with a caliper, over the metal and not over a rubber cover, and match that figure to the adapter. Get it wrong and the clip-on either will not seat or will not sit square, which shows up as a shifted point of impact rather than as an obvious fault. The clip-on FAQ walks through the same measurement from the optic's side.
Mounts and rings for thermal weight
A thermal sight is heavier than day glass and carries that weight further forward, so the mount is doing more work than the one it replaces — and every shot tests it. That is an argument for rings and mounts specced for the load rather than the cheapest set that fits the rail, and for checking fasteners after the first outing. Zero retention lives in the mount at least as much as in the optic.
Power discipline
Batteries are consumables and belong in the kit as spares, not as an afterthought — the night a cell dies is the night you needed it. Cold makes it worse: capacity drops as the temperature falls and a cell that reads full in a warm truck can fold on a long sit. Carry a spare warm, in a pocket rather than in the pack, and swap before the display starts warning you.
Sized to fit
Adapters matched to objective diameters — the measurement that makes or breaks a clip-on.
Built for the recoil
Rings and mounts specced for thermal weight on centerfire rifles.
Power that shows up
Batteries and spares that keep the season running — cold mornings included.
One-house match
Made to pair with Night Pearl optics — no guesswork, no adapter roulette.
Accessories — frequently asked
Measure the outer diameter of your day scope's objective bell — over the metal, at its widest point — and match that figure to the adapter. It is the only measurement that decides fit. If your scope sits between sizes or wears a permanent cover, send us the model and we will confirm before you order.
Where the interface is a standard one, yes — rings and mounts are built to common rail and ring standards rather than to our optics alone. Specific fit is a product-page question, so check the listing for the model you have; we would rather you asked than guessed.
The 16650 cell used by the Fox, SEER and Oracle devices. Each battery listing names the devices it serves — go by that rather than by the size alone.
It varies by item and is stated on the product page — the optics warranty does not automatically extend to everything that mounts to them. The Ultimate ring mounts, for example, carry a lifetime warranty. Check the listing, and ask us if it is not stated.
