HDD MK48L® & MK48L-DG® 7.62 NATO MACHINE GUNS

NEW DESIGN MK48L®, "L" STANDS FOR LONGER, THE RECEIVER IS 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. THE HDD MK48L® WITH A LONGER RECEIVER AND LONGER ACTION TRAVEL ETC MAKES THIS MACHINE GUN VERY RELIABLE.  EVEN DIRTY AND IN EXTENDED FIREFIGHT CONDITIONS THE HDD MK48L® KEEPS ON FIRING. THE OTHER ADVANTAGE OF THE HDD MK48L® IS FELT RECOIL IS REDUCED SO IS EASIER TO PUT MORE HITS ON TARGET. 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 MK48L-DG® IS A LONGER FINNED BARREL GUN WITH SPADE GRIPS FOR DOOR GUNNERS IN AIRCRAFT OR VEHICLE MOUNTS.
