No. The Wilson Combat AR-15 Billet Stripped Upper Receiver in .458 SOCOM takes only two caliber specific parts-a .458 specific bolt and barrel. It is designed to be used with only .458 SOCOM with an ejection port modified specifically for .458.

this is only caliber specific cause they stamped 458 Socom on the receiver. 458 and 450 bushmaster literally uses the same bcg but not the same barrel. it SHOULD work but I wouldn't suggest doing it since it's stamped as use for a 458 and might would deem it illegal if used for a 450.
