Steiner 8700-MPS MPS Micro Pistol Sight, Enclosed 3.3 MOA Red Dot
Product description
Choosing a pistol sight often comes down to whether you want an open emitter or a compact enclosed design. The Steiner MPS combines an enclosed emitter with 1x magnification and a 3.3 MOA red dot, giving handgun users a clear aiming reference while keeping the sight compact.
Its aluminum construction, recessed window, and metal hood help shield the front lens and emitter from objects and exposure to rain, mud, dust, and debris.

The true 1x view supports both-eyes-open use, helping keep the surrounding scene in view while aiming. The dot’s 3.3 MOA size is designed for a clear aiming point, while the side-mounted raised control makes brightness adjustments accessible on the optic. A flashing red indicator signals low battery. The battery compartment is accessible without removing the sight, so battery changes can be made while it remains mounted.
Compatibility & requirements
The MPS is designed for an ACRO footprint and fits many optic-ready pistols when used with a compatible ACRO baseplate adapter. It can also be mounted on a Docter plate and works with other manufacturer adapters. The mounting plate is not included, so select an adapter that matches both the pistol’s optic cut and the sight’s footprint before installation. Follow the adapter and firearm manufacturers’ installation instructions to secure the optic correctly.
Everyday use
For range practice or other handgun applications, the enclosed emitter keeps the aiming system shielded from environmental debris, while the 1x view supports keeping both eyes open. The eight brightness levels offer adjustment for different lighting conditions, including two settings intended for night-vision use. The sight’s auto-off feature activates after 13 hours, and the stated battery life is up to 13,000 hours.
Buyers often praise the lens clarity, crisp dot, and solid construction. Feedback on mounting and durability is more mixed, with some reports of plate or screw issues and one report of a break after 180 rounds. Choosing the correct adapter and following its installation guidance are practical parts of setting up the sight.
Buying verdict
The Steiner MPS is a focused choice for handgun owners looking for a compact enclosed-emitter sight with a 1x view, adjustable dot brightness, and a battery compartment that can be accessed while mounted. Its ACRO footprint also gives buyers a defined starting point when selecting an adapter for an optic-ready pistol. Steiner’s Heritage Warranty covers repair or replacement of defective products for the product’s lifetime, damage, loss, and theft are excluded.
