This newly redesigned Gen2 MBUS (Magpul Back Up Sight) from Magpul Industries is an economical folding backup sight that is injection molded. This front sight is adjustable for elevation and will fit most 1913-standard Picatinny handguards. This product should not be mounted on a gas block front rail due to it's polymer construction.
This item includes only the front sight and is not sold in a pair, and is proudly manufactured in the USA by Magpul Industries. These sights are also available in an FDE color from Hawktech Arms.
