UTG Spring-loaded front and rear sights utilize a spring-loaded sight tower that locks into place both in the folded and deployed positions. A deliberate push of the Posi-lock push button deploys the sight tower which automatically locks it into its upright position, preventing the sight tower from collapsing when accidentally bumped into something. To collapse the sight towers one must simply push and hold down the Posi-lock push button while simultaneously folding the sight tower down until it clicks and locks into place. The front sight uses a standard A2 front sight post making it interchangeable with other aftermarket posts of equivalent dimensions. The rear sight features a tool-less windage adjustment wheel and dual aiming apertures suitable for a variety of different scenarios. Both are precision machined from aircraft aluminum with a matte black finish and utilize a single locking Torx screw and square-shaped integral recoil stops for a secure and repeatable zero hold on MIL-STD-1913 Picatinny Rails.
