This weapon, as the version before it (HK23A1) could be switched over from 5.56x45mm to 7.62x51mm by changing the barrel, bolt, mainspring, and belt feed assembly. The change in calibers takes less than a minute, which was of interest to the US Military, but was not a requirement for the SAWs trials. Additionally, the belt-fed 5.56 XM262 can be changed over to a magazine fed weapon (using HK 33 magazines) by changing the bolt assembly, mainspring, and magazine feed well.
The optical sight was not used during the SAW program tests.
