against injury when the weapon was fired; an injury to Sgt. Payne of the 164th
Company was noted, with the remark "the lateral kick and vibration of the carriage upon recoil is destructive to the morale of the gun pointer". The lights provided for night firing also tended to become unscrewed, and the lamps for the sight's deflection scale were overly bright, apparently interfering with observation of the target. Major Burgess recommended switching to the barbette carriage M1903 and its firing lever system (as used on the 3-inch gun M1903), or modifying the masking parapet carriage with traverse and elevation gearing. In March 1913 the ordnance officers considered disabling the carriage in the up position by partially filling it with concrete. This had already been tested at
579:, built by other manufacturers. Unlike the disappearing carriages of most larger weapons, the carriage could only be retracted when the gun was at a particular traverse angle (in most installations 90° off the emplacement axis), thus it provided no concealment when in action. Approximately 120 of these were built between 1899 and 1903, and at least 111 of these weapons were emplaced between 1899 and 1905. The gun's elevation was from -5° to +12°; at first it was traversed by pushing on a shoulder bar, and in 1904 was modified with a wheel-and-gear traversing system. Open illuminated night sights were initially issued; in 1899 the

November 1931 the guns were declared obsolete, with many being donated to communities as war memorials and the rest scrapped. A number of these were presumably further donated to World War II scrap drives. At least 18 M1898 weapons survive as of 2016, along with four carriages under conservation.

In March 1920 the ordnance and coast artillery leadership determined that the M1898 should be declared obsolete and removed from service. All of the M1898 guns and carriages were removed from service in 1920, with the carriages being scrapped. Except in a few cases, they were not directly replaced at

Also in 1917, another serious deficiency appeared in the M1898: the piston rod (unclear if this was the recoil piston rod or the carriage raising piston) sometimes broke when fired, presenting a hazard to the gun crew and taking the gun out of service until repaired. The
