Third Echelon Development
THIRD ECHELON DEVELOPMENT
Third Echelon Development is based in Broken Arrow, Oklahoma, and makes parts for suppressed shooting. Its products are CNC machined and made in the USA.
Capitol Armory carries the Third Echelon Glock Gas Cap. It replaces the factory slide cover plate on your Glock with a steel plate that has a built-in shroud over the rear of the slide. When you shoot suppressed, the shroud directs gas and debris downward instead of toward your face. It installs in place of the factory plate, with no permanent changes to the pistol.
