HDD MK48 A1® & MK48 A1-DG® 7.62X51 NATO MACHINE GUNS

NEW DESIGN MK48 A1®, THE RECEIVER IS SLIGHTLY LONGER ON THIS WEAPON TO OVERCOME THE STANDARD MK48 RELIABILITY PROBLEMS. ON THE ORIGINAL MK48 THEY CRAMMED A 7.62 ACTION INTO A 5.56 RECEIVER AND THIS CAUSED A NO ROOM FOR ERROR SITUATION. UNLESS THE WEAPON IS KEPT VERY CLEAN AND WELL LUBED, MALFUNCTIONS WILL OCCUR. TO OVERCOME THE RELIABILITY PROBLEMS THEY OPENED UP THE GAS PORT AND NOW THE ACTION SLAMS TO THE REAR EVERY SHOT, THIS CAUSES EXCESSIVE RECOIL, SHORT RECEIVER AND BOLT LIFE AS NOTED BY US SPECIAL FORCES. THE HDD MK48 A1® WITH A LONGER RECEIVER AND LONGER ACTION TRAVEL ETC MAKES THIS MACHINE GUN VERY RELIABLE.  EVEN DIRTY AND IN EXTENDED FIREFIGHT CONDITIONS THE HDD MK48 A1® KEEPS ON FIRING. THE OTHER ADVANTAGE OF THE HDD MK48 A1® IS FELT RECOIL IS REDUCED SO IS EASIER TO PUT MORE HITS ON TARGET. RECEIVERS DON'T WEAR OUT LIKE A STANDARD MK48 AND THE BOLT LIFE IS MUCH LONGER. THE WEIGHT OF THIS WEAPON IS THE SAME AS A STANDARD MK48 DUE TO WEIGHT SAVING DESIGNS LIKE THE FLUTED BARRELS WHICH ALSO HELPS WITH COOLING. THE MK48 A1-DG® IS A LONGER FINNED BARREL GUN WITH SPADE GRIPS FOR DOOR GUNNERS IN AIRCRAFT OR VEHICLE MOUNTS.

NEW EWA/HDD DESIGNED MK46A1 BOLT CARRIERS/SLIDES

NEW STRONGER BOLT CARRIER/SLIDE FOR THE 5.56X45 WEAPONRY. WE DEVELOPED THESE FOR OUR NEW MK46A1 GUNS. SINCE THE MAGAZINE ADAPTER HAS BEEN DROPPED ON THE NEW GUNS, MK46 & MK48, WE REDESIGNED THE SLIDE TO BE STRONGER THAN THE OLD M249 SLIDE THAT HAS THE MAGAZINE CUT OUTS. NO GAP IN THE BOTTOM MACHINING FOR STRENGTH AND LESS FLEX. THE BOLT CAM STOP LEG IS MUCH THICKER ON THESE CARRIERS SO SERVICE LIFE IS MUCH LONGER. WE DO THESE FROM HIGH QUALITY STEEL AND NICKEL BORON. THESE WILL WORK IN A OLDER M249 BUT FOR BELT FED USE ONLY, NO MAGS. NEW MILITARY CONTRACT GUNS HAVE THIS SUPERIOR BOLT CARRIER/SLIDE AND THE PART LASTS LONGER WITH BETTER RELIABILITY.

NEW STRONGER BOLT AND BOLT CARRIER/SLIDE FOR THE MK48, MK48A1 WEAPONRY.

NEWLY DEVELOPED MK48 BOLT CARRIER WITH THICKER FRONT LEFT BOLT STOP LEG. SEE PIC, LHS CARRIER IS A HDD, RHS IS A STANDARD FN. THE HDD CARRIER ALSO HAS A LARGER BOLT BARREL HOLE. THE STANDARD BOLT HAS A REAR SHAFT OF ABOUT  .411"/10.44MM DIAMETER. THE HDD BOLT HAS A REAR SHAFT DIAMETER OF .464"/11.80MM. THIS FIXES TWO OF THE PROBLEMS NOTED BY US SOCOM IN THIER EXPERIANCE WITH THE MK48, 7.62 MACHINE GUN. THE STANDARD BOLT  CARRIER FAILS BY THE BOLT STOP LEG BREAKING OFF AFTER A FAIRLY SHORT SERVICE LIFE. THE HDD CARRIER IS A LOT STRONGER BY TWO MEANS, FIRST IT IS A LOT THICKER, SECOND IT IS MADE FROM HIGHER GRADE STEEL. 

THE PIC OF THE BOTTOM OF THE MK48 BOLT CARRIERS SHOWS THE HDD CARRIER, (THE ONE MARKED WITH OUR CODE 8BZD1), IS STRONGER BECAUSE IT IS MACHINED CONTINUOUS WITH NO GAP. THIS PREVENTS THE FLEXING THAT CAUSES PREMATURE STRESS CRACKS ETC.

THE STANDARD MK48 BOLTS FAIL AT AROUND 10,000 ROUNDS FIRED, (US SOCOM VERIFIED ROUND COUNT), THE REAR SHAFT BREAKS JUST IN FRONT OF THE CAM LUG. THE HDD MK48A1 BOLTS HAVE A THICKER REAR SHAFT AND REVISED CAM LUG. THE THICKER SHAFT AND HIGHER GRADE STEEL HAS MADE THIS PART MUCH STRONGER AND IS NOW LONG LASTING.
