The 5-20x50 PM II Ultra Short ECOS-O is, as a complete system, the ideal universal solution for ultra-short rifles in combination with night vision attachments. The red dot sight mounted on top as a "piggyback solution" completely covers the close-fighting range, while the scope, with its 5-20x magnification, is ideal for target identification and the perfect mid- to long-range shot. The compact elevation turret with 350 clicks is easy to overlook with the red dot sight and offers a large enough adjustment range to compensate for the bullet drop of various calibres. Thanks to the scope's short design, there is easily enough room on the rifle in front of the scope for night vision and thermal imaging attachments.
