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. When the gun is fired, high pressure gas generated by the burning propellant pushes the projectile forward.
Boresighting is a method of visually pre-aligning a firearm barrel's bore axis with the target, in order to more easily zero the gunsight (optical or iron sights). The process is usually performed on a rifle , and can be accomplished either with the naked eye, or with a specialized device called a boresighter .

Despite all these advances, the Abrams still retained the 4-man crew of the M60 tank as the autoloader was considered unproven and risky. Over 3,200 M1 Abrams were produced and first entered US Army service in 1980. About 6,000 upgraded M1A1 Abrams were produced and used a 120 mm smoothbore cannon, improved armor, and a CBRN protection system.
A number of considerations had led the U.S. Army and its contractors to favor the Army's standard M68 105 mm gun over Germany's 120 mm Rheinmetall Rh-120 smoothbore gun for the XM1 Abrams. To begin with, the 105 mm gun was "the smallest, lightest, and least costly gun adequate for the job."
Some of the Arsenal's most successful products include the M198 and M119 towed howitzers, and the gun mount for the M1 Abrams, main battle tank for the Army since the 1980s. About 250 military personnel and 6,000 civilians are employed there. The population from the 2020 census was 182 people.
[19] [22] Although the M256 120mm smoothbore gun was chosen to be the main weapon of the M1 Abrams in 1979, the ammunition for the gun was still not fully developed, thus delaying its fielding until 1984. [14] The early production versions of the M1 Abrams (M1 & IPM1) were armed with the M68A1 [23] for two reasons. First was due to the large ...
