Bore evacuator on an M1 Abrams. The evacuator is a passive device generally consisting of a ring of holes drilled into the barrel, surrounded by a cylindrical pressure reservoir that is sealed to the barrel's surface.

[75] 3,273 M1 Abrams were produced 1979-85. [citation needed] An improved model called the IPM1 was produced briefly from October 1984 to May 1996 and contained small upgrades. [76] It was initially planned to retrofit the M1 and IPM1 with a longer barrel version of the 105 mm M68 gun.
