THE NEW MK48A1 MACHINE GUNS

HDD MK48A1® BELT FED MACHINE GUN,  7.62X51 NATO OR 6.5CM.

THE MK48A1® BY HDD WAS DEVELOPED WITH A LONGER RECEIVER TO FIX MK48 RELIABILITY PROBLEMS. THESE USE THE SAME PARTS AS A STANDARD MK48 EXCEPT THE RECEIVER AND FEED COVER ARE SLIGHTLY LONGER AND THE BOLT AND SLIDE ARE BEEFED UP TO IMPROVE SERVICE LIFE AND RELIABILITY.

 THE STANDARD MK48 HAS A VERY SHORT BOLT LIFE AND A VERY SHORT RECEIVER LIFE. THE SHORT LIFE IS CAUSED BY CRAMMING A 7.62X51 ACTION INTO A 5.56X45 RECEIVER AND OPENING UP THE GAS PORT TO MAKE THE MOVING PARTS GO ALL THE WAY BACK EACH CYCLE. THIS IS WHY THE RECEIVER STRETCHES FROM THE SLAMMING AND THE BOLT FAILS WITH SUCH A SHORT SERVICE LIFE. THE STANDARD MK48 SLIDE ALSO HAS A SHORT SERVICE LIFE AS THE BOLT CAM STOP LEG BREAKS OFF. THE MK48A1 HAS A SLIGHTLY LONGER RECEIVER WHICH CURES THESE PROBLEMS BY PROVIDING A LONGER ACTION TRAVEL AND HAS LESS FELT RECOIL SO GETTING MORE HITS ON TARGET IS EASIER. HDD DESIGNED BOLT HAS A THICKER REAR SHAFT DIAMETER AND HDD DESIGNED SLIDE WITH BEEFIER CAM STOP LEG FIXES THESE PARTS. THE HDD MK48A1 BOLT AND SLIDE WILL FIT A STANDARD MK48 AND IS HIGHLY RECOMMENDED. BOLT AND SLIDE MUST BE USED TOGETHER OF COURSE AS THEY ARE MATCHING PARTS. THE LONGER ACTION TRAVEL ALLOWS THE BOLT TO LOCK FURTHER TO THE REAR WHICH GIVES A LONGER RUN UP BEFORE STRIPPING A ROUND FROM THE BELT, MUCH MORE RELIABLE STRIPPING AND FIRING OF THE OPEN BOLT DESIGN.

MULTI CALIBER RECEIVER WITH CONVERSION KITS TO 5.56 NATO, 300BLK, 7.62X51 AND 6.5 CM AVAILABLE. 

THESE COME WITH A LIGHT BUT RUGGED B0LT ON PICATINNY RAIL HAND GUARD WITH MIL-STD 1913 RAILS AND M-LOK SLOTS.
