HDD MK48A1® BELT FED MACHINE GUN,  7.62X51 NATO.

 NEW HDD DEVELOPED AND MANUFACTURED LONGER MK48 RECEIVER AND REDESIGNED BOLT & SLIDE FOR SUPERIOR RELIABILITY.  THE LONGER RECEIVER GIVING LONGER BOLT/ACTION 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" WHICH THEY TRIED TO FIX BY OPENING UP THE GAS PORT. THIS 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. 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 HDD BOLT HEAD IS MUCH STRONGER AND MADE FROM PREMIUM STEEL, DEEP HEAT TREATED AND NICKEL BORON.
