"Thermal-actuated transition between closed-bolt and open-bolt operation without operator intervention in both semi-auto and full-auto modes"
I've never seen a cookoff first hand. I've done multiple mag dumps to appease certain ACP practices after a long range day with an M4A1. I took precautions in the event of a cookoff, however it never happened. Is the danger of a cookoff real enough to warrant a 11 pound weapon? The standard MK16 weighs 7.24 lbs., long barrel model is 7.74lbs.
Granted, this weapon is for the "Infantry Automatic Rifle" role. However, for six more pounds one may carry an M249 SAW with belt feed capability. I have never used a drum magazine for the STANAG platform, so I cannot say as to whether that may be a viable option.
I personally see the HAMR being marketed as a "safe assault rifle", where for a 4lb. increase in weight, the danger of a cookoff is absolved.
What is your opinion on the IAR role?
What are the circumstances for a M4 platform to have a cookoff?
How might the "thermal actuated transition" mechanism function?
One thing I brought from the advertisment is that after firing enough rounds to warrant transition to open bolt fire, when the weapon has cooled to a predetermined temperature it will automatically revert to closed bolt thereby chambering a round without operator input.
