This Magpul backup sight is constructed of impact-resistant polymer that resists operational abuse. A spring-loaded flip-up system easily deploys from either side, where detent and spring pressure keep the sight in place. Protective wings prevent damage to the aperture to ensure accurate aim, while a detent knob offers quick windage adjustment. Compatible with most 1913 Picatinny receiver rails, the Magpul MBUS Rear Sight offers a dual aperture backup sight tailored to AR15/M16 platforms.<br />\r\n<br />\r\n<strong>Specs:</strong><br>\r\n\r\n<ul>\r\n\t<li>Model #: MAG248</li>\r\n\t<li>Length Stowed: 2.6 in.</li>\r\n\t<li>Length Deployed: 1.5 in.</li>\r\n\t<li>Weight with Hardware: 1.3 oz.</li>\r\n\t<li>Height above Rail&nbsp;(Stowed): 0.51 in.</li>\r\n\t<li>Center of Aperture to Top of Rail: 1.42 in.</li>\r\n\t<li>Windage Adjustment:\r\n\t<ul>\r\n\t\t<li>~0.5 MOA (0.547in./100m) per click with a 20 in. sight radius</li>\r\n\t\t<li>~0.7 MOA (0.754 in./100m) per click with a 14.5 in. sight radius</li>\r\n\t</ul>\r\n\t</li>\r\n</ul>\n\nFeatures:\n\u003cul>\n\u003cli>Sight can be folded with either the large or small aperture in position\u003c/li>\n\u003cli>Compatible with most 1913 Picatinny/STANAG 4694 receiver rails\u003c/li>\n\u003cli>Spring-loaded flip-up sight deploys easily from either side\u003c/li>\n\u003cli>Impact-resistant polymer is both lightweight and durable\u003c/li>\n\u003cli>Protective wings prevent damage to the apertures\u003c/li>\n\u003cli>Detent and spring pressure keep sight in place\u003c/li>\n\u003cli>Detent knob offers easy windage adjustment\u003c/li>\n\u003cli>Two apertures: one large, one small\u003c/li>\n\u003c/ul>\n\n"
