@nugger early mp5 competitor from walther that tried to compete with big reciprocating mass up top paired with light bolt. more expensive mp5 roller delay won out with governments and crushed MPL outta the market. still looks real sick tho

YOU KNOW HOW IN THE RHUZI FAMILY OF SMGS THE TELESCOPING BOLT IS MADE UP OF A TUBE WITH CUTOUTS AND A BREECH BLOCK THAT NESTS INSIDE THE TUBE? WHAT IF THE BREECH BLOCK WAS RLY LIGHT AND GOT STOPPED RIGHT BEHIND THE FEEDING POSITION AND POPPED OUT OF THE TUBE "CARRIER" WHICH CONTINUED TO RECOIL
SHORT BOLT TRAVEL, LONG SMOOTH AND LIGHT RECOIL IMPULSE, LIKE AN AR BUFFER
NOW SHORT BOLT TRAVEL DOESN'T MEAN MUCH IN THIS SITUATION AS YOU NEED THE SAME RECEIVER SPACE BEHIND THE BOLT FOR THE CARRIER/BUFFER TO TRAVEL INTO
BUT
CONSIDER A WAY TO MOVE THAT MASS FORWARD, UNDER THE BARREL
SAY THE BOLT IS JUST AN L-SHAPED TAB OF THICK SHEET STEEL BENT INTO SHAPE, WITH TWO RODS WELDED TO IT ON EITHER SIDE LIKE AN AUG
THE GUIDE RODS LOCATE IT TO THE BORE AND THE MAGAZINE, THEY GO ALL THE WAY TO THE FRONT OF THE BARREL
BUT THEY ALSO ACT AS GUIDE RODS FOR A BIG DUMB LEAD WEIGHT THAT SITS UNDER THE BARREL IN A TUBE IN FRONT OF THE TRIGGER GUARD, WITH A RECOIL SPRING BEHIND IT, AND IT MAKES UP MOST OF THE MASS IN THE BOLT GROUP
