Ultra Shot M-Spec Bottom Line Up Front

The Sightmark Ultra Shot Military Specification (M-Spec) Locking Quick Detach (LQD) Reflex Sight is a rugged, lightweight, versatile shooting optic suitable for various high demand short to intermediate-range applications.

Intuitive and ease of use with a balance of straightforward controls and all the features any avid shooter would want at an excellent price point make this reflex sight from Sightmark a smart buy.

The Red Dot Sight Review

Let’s get started by covering the features and everything you will get with this popular red dot sight.

Features

This reflex sight has a robust housing cast from lightweight magnesium alloy for a tough outer body construction that includes a protective hood. The Sightmark Ultra Shot M-Spec additionally has a patented integrated sunshade that will prove useful in bright sunlight and other intense light conditions.

The magnesium alloy is stronger than 6061 aluminum alloy without the weight, bringing the optic in at 10.2 oz. Ideal for keeping the weight down on whatever firing platform you decide to mount the sight on.

A more substantial form factor allows for a shockproof frame that can withstand recoils up to .50 caliber. The larger form also allows for a wide field of view (105 ft at 100 yards) along with the standard unlimited eye relief, which is one of the advantages of a reflex sight.

When it comes to mounting, the M-Spec Reflex Sight with Locking Quick Detach is ready to install out of the box to a Weaver/Picatinny military standard rail interface system. It operates with an adjustable single lever arm that folds to the rear allowing for a fast solid mount with no play. The lever also features a locking slide to ensure that the sight is not unseated by gear snags or something similar.

The sight has an IP68 waterproof rating with a manufacturer specified submersion depth of 40 feet. With this rating, you can expect this reflex sight to stay dust and moisture-free, ensuring a fully operational sight when you need it.

Power and Controls

A single CR123A battery powers the Sightmark Ultra Shot M-Spec Reflex Sight. With a low power consumption design, you can expect a battery life of up to 2,000 hours. The sight has a built-in low battery indicator along with a 12-hour auto shut-off for those days when you forget.

The sight can also be configured with a motion-sensing on/off activation that turns the reticle off after five minutes and on again with movement.

Reticle

The sight has a red 65 Minute of Angle (MOA) ring reticle for rapid target acquisition with a 2 MOA center dot for more precise shots. The sight is controlled by a single digital switch for on/off and reticle brightness adjustment.

The sight has six reticle brightness levels for daytime use and six reticle settings in night vision mode allowing the use of the sight with generation 1, 2, and 3 night vision systems.

Interlok Adjustment System

The Sightmark Ultra Shot M-Spec Reflex Sight features the Interlok adjustment system. This internal retention system ensures windage and elevation adjustments remain zeroed during recoil. Most reflex sights typically require the adjustment system to be unlocked using a screw or set of lock screws.

The windage and elevation adjustments are in 1 MOA increments. The changes are made with the included Allen wrench. The Interlok adjustment system removes the need for a locking screw so shooters can make adjustments on the fly.

Optics

The lenses are constructed of dual-pane glass with scratch-resistant red anti-reflective (AR) coating. With a parallax-corrected lens system, the Ultra Shot allows shooters to sight accurately from 10 yards to infinity and maintain a hard to detect posture until shots are fired.
