How reliable is your primary weapon?
How long can it go til it blows?
What are it's limits?
I see some anons discussing the effectiveness of the AR-15 in combat, often times claiming it's lack thereof.
Many anons have concerns that their rifles would jam or otherwise become inoperable in a theoretical combat situation.
I feel that this is a good opportunity to clarify some differences between cyclical Rof, an effective Rof, and a sustained Rof
The numbers for each of these are as follows:
>cyclical Rof ~700-800rpm
>effective Rof ~45rpm
>sustained Rof ~12-15rpm
As you can see, the difference in dakka is significant. I have linked a video showing what happens to a fun at maximum (cyclical) rpm.
In this video he burns through ~400+ rounds rather quickly, which generally speaking is over the regular combat load for an average soldier, he is also firing non-stop, which almost no average soldier would do.
Some other details to note here are that the rifle he is using is among the cheapest available on the market (at the time of the video). The barrel is a standard mil-spec barrel, I suspect that a heavy barrel would be best. With that he also notes that it is already hot where he is while firing.
With his skinny barrel and high outdoor temps, I feel this is a good example of what many would experience with a run of the mill rifle without optimizations.
The effective rof of 45rpm is what can be expected of a man in heavy combat, meaning that he has a lot of trigger time, this is also fairly unlikely in most combat situations. While this would cause a weapon to overheat eventually, it would still be operation for a fairly long period of time, given that it has time to cool down in between periods of fire.
For a sustained rof, precise and accurate fire, at regular intervals. One could have his weapon operational almost 100% of the time with almost no fear of ovePost too long. Click here to view the full text.
