HDD MK48A1® BELT FED MACHINE GUN, NEW HDD DEVELOPED AND MANUFACTURED LONGER MK48 RECEIVER AND REDESIGNED BOLT & SLIDE FOR SUPERIOR RELIABILITY.  THE LONGER RECEIVER GIVING LONGER BOLT TRAVEL OF THE MK48A1® CURES THE RELIABILITY PROBLEMS WITH THE ORIGINAL MK48 WHICH WAS A 7.62 ACTION CRAMMED INTO A SMALL 5.56 RECEIVER. THIS CAUSED A "NO ROOM FOR ERROR SENARIO" WITH THE DISTANCE FROM THE BOLT HEAD TO THE BELTED CARTRIDGES BEING TOO SHORT, NOT ENOUGH RUN UP ROOM TO CLEANLY STRIP A ROUND OUT OF THE BELT. THEY TRIED TO FIX THE SHORT CYCLE PROBLEM BY OPENING UP THE GAS PORT WHICH MADE THE ACTION SLAM TO THE REAR CAUSING EXCESSIVE WEAR, HIGH FELT RECOIL AND SHORT RECEIVER AND BOLT LIFE. THE STANDARD MK48 RECEIVER ONLY LASTS AS LITTLE AS 50,000 ROUNDS UNTIL IT IS THEN STRETCHED OUT OF SPEC. THE STANDARD MK48 BOLT ONLY LASTS AS LITTLE AS 10,000 ROUNDS BEFORE CRACKING. THE LONGER ACTION TRAVEL OF THE MK48A1® ALLOWS MUCH BETTER RELIABILITY, MUCH LESS WEAR AND HAS LESS FELT RECOIL FOR SUPERIOR HITS ON TARGET. PARTS INTERCHANGE BETWEEN THE MK48 AND MK48A1® IS 90% WITH THE RECEIVER AND FEED COVER BEING THE DIFFERENCES. THE HDD DESIGNED SLIDE IS MUCH STRONGER AND IS MADE FROM PREMIUM STEEL WITH NICKEL BORON. THE SLIDE HAS A THICKER BOLT CAM STOP TO PREVENT THIS PART BREAKING. THE HDD BOLT HEAD IS MUCH STRONGER WITH A LARGER REAR SHAFT SIZE AND MADE FROM PREMIUM STEEL, DEEP HEAT TREATED AND NICKEL BORON. THE SUPERIOR HDD SLIDE AND BOLT WILL FIT A STANDARD MK48 AND IS A HIGHLY RECOMMENDED UPGRADE. CHOICE OF 7.62X51 NATO OR 6.5 CREEDMOOR. LIGHT WEIGHT SQUAD AUTOMATIC WEAPON. MULTI CALIBER RECEIVER WITH CONVERSION KITS TO 5.56 NATO, 300BLK, 7.62X51 NATO AND 6.5 CREEDMOOR  AVAILABLE.
