The Liberty Precision Machine Eclipse Flash Hider, 13.7-inch Pin-Weld configuration (Liberty part no. LPM-2007), is a .30 caliber muzzle device threaded 1/2×28 and sized specifically to be permanently pinned and welded onto a 13.7-inch barrel, bringing the total barrel length up to 16 inches. Liberty Precision Machine built the Eclipse as a standalone flash hider rather than a suppressor mount, and recommends always confirming alignment before use. It’s the option for anyone building a 13.7-inch-barreled AR-pattern rifle who wants to reach 16 inches without giving up flash reduction.
