SORRY FOR ANY CONFUSION REGARDING MY PREVIOUS COMMENTS ABOUT THE R0921HB CONVERSION. ALTHOUGH I HAVE HAD HALF A DOZEN OR SO PASS THROUGH THESE DOORS, I REALLY KNOW LITTLE ABOUT THEM AND ANY SPECIAL APPLICATION.

COLT, BUILDING SOME 14.5" UPPERS FOR THE L.E. MARKET, USED SOME OF THESE MILITARY  R0921HB HEAVY BARRELS BY MISTAKE. THAT'S HOW SOME CAME INTO CIVILIAN HANDS.

THE R0921HB BARREL IS CONSIDERABLY [!] HEAVIER THAN THE STANDARD M4 CONTOUR BARREL, MORE LIKE THAT OF A COLT CIVILIAN HEAVY CONTOUR BARREL UNDER THE HANDGUARDS, EXCEPT FOR THE FACTS IT IS TURNED DOWN NEAR THE FRONT SIGHT FOR THE KNIGHT'S M4 RAS ATTACHMENT AND HAS THE TWO FLATS AFT OF THE FRONT SIGHT FOR THE M203 MOUNTING POINT. LOOKS JUST LIKE A REGULAR M4 BARREL FORWARD OF THE FRONT SIGHT. THE ONLY PIC I HAVE HAS TOO MUCH RESOLUTION TO POST ON AR15.COM, UNFORTUNATELY.

AS "SF" SO ELOQUENTLY STATES, 100 POUNDS OF LIGHTWEIGHT, HIGH SPEED GEAR STILL WEIGHS 100 POUNDS. DO SPEC-OPS TYPES NEED OR WANT THIS EXTRA WEIGHT? OPINIONS ARE CERTAINLY GOING TO VARY WITHIN THE COMMUNITY, BASED ON THE MISSION AT HAND.

ARE "THEY" TRYING TO MAKE AN M4 INTO A SAW? DOES COPIOUS QUANTITIES OF FULL AUTO FIRE FROM A MAGAZINE-FED M4 REALLY HAVE A PLACE IN "THEIR" TACTICS?

AT MID-SOUTH, WHEN THE HIGH SPEED BOYS ARE IN THE KILL HOUSE, ALL I HEAR IS REALLY FAST SEMI DOUBLE-TAPS... FROM THEIR 10.5" UPPERS, WHICH HAVE THE LIGHTWEIGHT M4 CONTOURED BARRELS UNDER THE HANDGUARDS.

ALL I KNOW FOR SURE IS I'M GLAD I KEPT ONE OF THESE HB'S FOR MYSELF. BUT I PREFER MY LMT 10.5" UPPER FOR CLOSE -IN WORK AND MY LONGER SPR FOR FURTHER OUT.
