I'm not saying you're wrong for inquiring about this, but the fact is the SR15 was not designed to be a race gun or have the fastest time on "double taps" at distance. It was designed to be a complete weapon system for combat/duty use with all components integrated effectively and operating efficiently to produce the best possible reliability and performance in all types of conditions with various types of ammo. I'm not trying to define the rifle for KAC as I'm sure Jack can do a better job of that, but that's my take on it.
I also have a couple ARs that are set up purely for competition and they don't move under recoil due mainly to the gas system/ammo combination and muzzle break. I have them tuned perfectly for the way I want, which also means I may change ammo based on the required distance to targets and precision I require for a particular stage. This is the same reason why I also have a couple ARs set up purely for long range precision...they are heavy with premium barrels, headspaced bolts, great glass, cans that allow for minimal POI shift, etc...and I baby them. But I would never use them for a 2 or 3 gun comp. Similarly, I will never grab a competition gun and ask it to run certain ammo or operate in adverse conditions...but I will reach for the KAC there EVERY SINGLE TIME. If flat out runs.
I will say this though in reference to the SR15 gas system and recoil impulse...if I didn't have any ARs tuned for competition and only had my combat/duty rifles, the KAC would be the 1st one I would grab to go run in a 2 or 3 gun comp. IMO it really is that good and shoots better than any other factory rifle without any modifications.
