The XL73E2 was a prototype light machine gun designed by RSAF Enfield.
Overview
The XL73E2 was a similar design to the earlier XL65 LSW; it was a modified assault rifle with a longer barrel and bipod. Like the XL65 LSW, it did not have a quick-change barrel and retained the 30-round magazine of the assault rifle variant, which made it an impractical light support weapon. It performed poorly in certain conditions, and so it was improved as the L86 Light Support Weapon, but even then it did not gain a quick-change barrel or extended magazine.
