Something telling here:
“Another design requirement for Horizon’s Lord rifle was the capability of changing the caliber. That’s why the bolt head and barrel of the rifle can be easily detached. In a matter of bolt head and barrel change, the caliber of the rifle can be changed to .416 Barrett, .460 Steyr, .50 BMG, or 12.7x108mm. Even easier, in a matter of only a barrel change, the rifle can be converted to 14.5x114mm or 23x115mm.”
They didn’t develop it... It too conveniently fits our barrels and bolts.
