Bushnell Rimfire Optics rifle scopes are designed for all rimfire cartridges from .17 HMR to .22 WMR. All Bushnell Rimfire Optics come in a 1-inch main tube, made from a single piece aluminum. All models have parallax adjustment with a side turret or a parallax ring on the objective and multi-coated lenses for more light transmission and image sharpness.
The parallax adjustment goes from 10 meters to infinity, with marks from 10 to 300 meters. The scopes have normal Multi-x reticles, or specific BDC (bullet drop compensation) reticles for each rimfire cartridge. The reticles are set in the second focal plane (reticle size doesn't change with zoom) so the reticle doesn't cover a lot of the target at big magnifications. All Bushnell Rimfire Optics rifle scopes are fully waterproof and fog proof.
The Bushnell Rimfire Optics rifle scopes can only be mounted with 1-inch rings.
