Magpul PTS Back-Up Sight (MBUS), Rear Sight FDE

Magpul’s MBUS sights are designed as low-cost alternatives to other back-up iron sights (BUIS) on the market. Made from Magpul’s signature high quality polymer, these sights are durable, yet very lightweight. The rear sight is adjustable for windage, and features a dual aperture: one “tight” aperture for precision, and a “wide” aperture for closer range shots. To deploy the sight, simply press down on the front or on one of the side levers, and the spring-assisted sight will pop into place.

Features:

- Lightweight, durable polymer construction
