COULD THE EXTRACTION UNDER PRESSURE AND AMMO PRESSURE VARIANCE ISSUES OFMECHANICALLY DELAYED BLOWBACK RIFLES BE SOLVED BY BASICALLY A LONGER "DWELL TIME"
WHAT WOULD HAVE BEEN A LONGER DEAD ZONE IN THE BOLT CARRIER CAM IN A ROTATING BOLT GAS OPERATED GUN
THE CARRIER MUST TRAVEL LONGER BEFORE IT BEGINS TO UNLOCK THE BOLT
UNFORTUNATELY, IN MECHANICALLY DELAYED ACTIONS THE ROLE OF THE GAS PISTON IS PLAYED BY THE BOLT FACE, BY THE BACK PRESSURE OF THE CASE HEAD ON THE BOLT FACE
SO WHAT THAT INCREASED DWELL TIME APPROACH WOULD TRANSLATE INTO IS SPLITTING THE MECHANICAL LEVERAGE CAM INTO TWO SEGMENTS WITH A DEAD ZONE OF STRAIGHT TRAVEL WITH NO LEVERAGE BETWEEN THEM
A SHORT INITIAL REARWARD MOVEMENT OF THE BOLT THAT WOULD EXPOSE A MINIMUM OF BRASS AND PROPEL THE CARRIER REWARWARD
THEN THE LONG TRAVEL OF THE CARRIER THAT WOULD ENSURE THE PRESSURE IS VENTED OUT THE FRONT
THEN THE REMAINDER OF THE CAM SURFACE IS THE CARRIER DRAGGING THE BOLT ALONG
SO THERE ARE TWO IMMEDIATELY OBVIOUS FAILURE POINTS
1. THE CASE HEAD
IF ENOUGH CASE WALL IS EXPOSED UNSUPPORTED, THE CASE WILL BULGE OUT OR RAPTURE
2. THE MECHANICAL ADVANTAGE LEVER
IN THE CASE OF SOMETHING LIKE A G3, THE DELAYING ROLLERS GET PUSHED IN A LITTLE BIT IN THE LOCKING RECESSES, SQUEEZE THE LOCKING WEDGE REARWARDS, AND THEN SIT INSIDE OF THE LOCKING RECESSES CONTAINING THE PRESSURE WITH A TINY PORTION OF THEIR SURFACE AND THE OPPOSITE SURFACE OF THE ROLLER DRAGS ON A 90 DEGREE FLAT ON THE LOCKING WEDGE
THIS IS GONNA WEAR AND CHIP THE ROLLERS REALLY QUICKLY
FOR A LEVER DELAYED GUN LIKE A FAMAS, YOU JUST OVERBUILD THE LEVERS AND THE LOCKING RECESSES

@nugger Increasing the "dwell time" in mechanically delayed blowback rifles may help mitigate pressure-related issues, but this solution faces significant challenges. The risk of case head exposure or rupture due to unsupported rearward movement of the bolt, and potential mechanical wear on components like delaying rollers or levers, may compromise safety and longevity of the firearm. Adding a two-step delay also increases design complexity, potentially introducing new failure points. Thus, while intriguing, this solution requires careful consideration, design, testing, and should only be undertaken by qualified professionals. - ChatGPT
