This is a public service announcement for you.
Anything over 200 rds could possibly cook, It is harder to do with a 30 rd mag because the amount of time for the mag change.

Be careful:eek:
-
If your problem can’t be solved with a 200rd string, move up to a stronger caliber
-
Remember Rule #2.
And the point being -don’t be stupid and waste that many rounds ?:rolleyes: Cause no civy should ever get to that point! And 99% of soldiers would never get to that point either:rolleyes:
Or an open bolt machine gun.
Agreed,
The published Sustained Rate of Fire for the closed bolt IAR (M27,Hk416) is 65 rpm. So in 5 minutes I see a potential issue there, big jump from the M4 sustained rate of 12-15 rpm.
We designed the SAW-MAG as MOLLE attached pair to the 30 rder,
For closed bolt operation it was designed as a situational use. The HAMR is the only weapon truly capable of doing much more than that safely.
It does seem as though this is a forgotten subject that most people are not in touch with because you don’t tend to see it.
This is why I NEVER buy a used barrel/upper. :rolleyes:
You see the type of shooting I do, so one day I had to use my weapon at a demo. I knew it was going to be interested when they set out the steel targets about 200m out. They got prone, popped off a round, and started adjusting the iron sights, as it didn’t have any optics(not so fancy, I know). I saw a bunch of funny looks after a shot or two, then they started wanting to crack off the upper, so I did. That is when I noticed that I had a James Bond barrel, just like the beginning of the show. It would have been a nice shotgun barrel because smooth wasn’t the word, it looked polished. There was no sign of rifling, I would say that this only took about 15k rounds. I have never seen a throat erosion problem but long bursts on hot barrels is hell, that cool night effect is your riflling going down range. It seems to shed near the chamber first. God knows where your bullets are going but I bet they are nasty on soft tissue.
*What about a new “Support minded” closed bolt training, You see from this video that it takes 20 seconds to cook, well with an AR you can rest in an open bolt fashion by using the bolt catch, then you essentially have an open bolt weapon. The expelled round if pulled within a few seconds is of no real danger, and even if it pops in the open it is far less of a problem as it won’t do anything unless it is contained in a space somehow. I did this on a light barrel, if a heavy barrel is being upgraded for sustained fire it seems that this issue should be addressed.
