 Comparative evaluations for a new tank gun began in October 1958, with one highly favorable British 105 mm gun designated the ''X15E8'', which was also referred to as the "Ex [[20pdr OQF Mk.I (84 mm)|20 pounder]]" as it was derived from that gun design (and would later be more well known as the [[Royal Ordnance L7A1 (105 mm)|L7 gun]]). The American had developed a version of this gun designated the ''T254'', tested in the [[T95E1|T95E5 medium tank]], that used the same calibre and ammunition, but the gun tubes were not interchangeable with the X15E8. This was later developed into the ''T254E2'' which made the tube interchangeable with the British gun, though differed with a concentric bore evacuator compared to the British eccentric evacuator (slightly raised above the gun tube) which allowed greater gun depression over the rear engine deck. Another difference in the two guns was that the British breech block moved horizontally, while the American breech block moved vertically. During this development, Ordnance debated whether to move forward with the 105 mm or a lightened 120 mm T123E6 gun based on the [[M103]]'s [[M58 (120 mm)|120 mm M58 gun]]. However, the 105 mm was eventually chosen in accounting for the 120 mm's two-piece ammunition construction restricting the rate of fire. Ultimately, the American T254E2 with the British X15E8's gun tube and eccentric bore evacuator design was chosen as the basis of the XM60's gun. British-made gun tubes would be used until American-manufactured gun tubes could achieve similar accuracy specifications.  This 105 mm gun would be standardized as the '''105 mm gun M68'''.<ref name="Hunnicutt-1">Hunnicutt 1984, 152-155</ref><ref name="Hunnicutt-2">Hunnicutt 1984, 453</ref>
