No, I am not reinforcing your point that the Sport II is for "plinking"... detecting a lot of arrogance from that post. Different twist rates perform certain tasks better. The OP did not mention long range shooting in his use, but he did mention varmint hunting... and a slower twist rate is better for the smaller grain rounds. If he never plans to shoot his AR at 600 yards from a bench, then the 1:7 twist is not needed. Buy the rifle with the features that you will use, not because of what the military uses, or what some random stranger on the internet says.
Like I said IMHO YMMV. You seem to like to argue for the Sport II as the catch all answer to every AR15 problem. Clearly you like it. I think it is a great starter AR15 but honestly I can buy and upper and a lower from 10 different places for less and assemble a better rifle. Again IMHO. There is no need to call me arrogant. That is an ad homiem which only serves to distract from the actually statements I have made. You misrepresent what I have said in an attmept to prove you point.

I have S&W, CMMG, and BCM ARs... The BCM cost almost twice as much as what a Sport could be had for, but I guarantee it is not twice the rifle. I honestly have seen very little difference in performance between the two in my use. If you blindfolded me and had me shoot all three, I would only be able to tell the difference because of the different handguards.
I already addressed the law of diminishing returns and the subjective nature of a more expensive rifle. For you the BCM does not make sense. For others the stock will fit them better. The brake-comp will allow them to shoot faster and more accurately. Some people will like the KMR rail and the reduction in weight that it brings. Some will appreciate that the gun will be blemish free and will exhibit better fit and finish. For some that is worth $$$ for others it is not, the value is subjective.
Standing or sitting at a bench on a square range I agree the differences might not be worth it. For other it might. What if you want a 14.5" barrel? What it that is your think because of its portability is it worth more $$$$ to get that over a S&W Sport II? Clearly for you it might not be but for others it might be. Again the law of diminishing returns is in play and the subjective value of the upgrade cannot be universally applied. I cannot tell you universally that it is worth the coin but by the same token you cannot universally tell me it isn't. The difference between my logic and yours is that I have not claimed in any sense that my subjective preferences are universal.

You presented the 1:9 twist as a limitation of the Sport II's use as a varmint gun. Many varmint guns have an even slower rate than the Sport. The twist rate is not a limiting factor for varmint hunting what so ever. I don't know anyone who uses expensive, 77 gr rounds for varmint hunting. Hell, I use the cheapest 62 gr ammo I can get for pig eradication. Do you even hunt bro?
That again was not my intent. My intent was to point out that the Sport II as a varmint gun is a big compromise. I then made the point that if you want to do long range shooting the 1/9 will be a liability with 77gr and some 72-75gr ammo which is the prefer weight for long distance shooters. Who have again combined the two statements into a strawman in and attempt to discredit me when I have not made that argument. I have made 2 separate statements. Since there is confusion let me clarify.
1. The Sport II is not a dedicate varmint gun and in that role if one desires a rifle to fill that roll it might not be the best tool for the job.
2. If you want to shoot long distance with match grade accuracy beyond 500 yards the 1/9 twist of the Sport II will be a liability because most shooters looking to achieve that goal use 77gr ammo to accomplish the task.

Again, I don't see duty use or hard use listed in the OP's requirements. I wouldn't have an issue using a Sport II for a LE carbine. Hornady makes plenty of TAP ammo in 55 - 70 gr for LE use that will work fine with a 1:9 twist.
I certainly wouldn't have an issue using it for HD either. Home and hearth have been protected by less for years. The notion that somehow a Sport, or Ruger AR-556, or any other lower cost rifle is not up for a HD role is ridiculous. If you have $1500 to spend, which is better... $500 Sport, $500 rounds of ammo, and a training class, or a $1500 boutique rifle. I'll take the Sport and training, thank you.
You have 1* so if you are comfortable with the Sport II as a duty gun or a home defense gun then who am I to tell you different. I have not said that it cannot function in that role what I have said is that it would not be my choice. I even went as far as to say if that was my "issued" gun I could make it work but on my dime it would not be and it is not my first choice. Again we seem to be at a point of confusion where I have stated a subjective opinion and you have taken it as universal fact. Maybe I have not been clear enough. Maybe you just like to debate in this manner which is fine. I enjoy a good debate as long as we do not resort to logically fallacies in order to prove our points.
In the end people must make their own choices. The Sport II is IMHO a good rifle for the price point and that everyone who buys one should understand its limitations and know that there are other options. Those other options might cost more or with a little knowledge maybe even a little less but in the end the individual must decide. My replies in this thread were addressing the OPs admitted lack of knowledge about the world or AR15s and other comments directly made about the capabilties of the Sport II. Nothing more nothing less.
I firmly believe that Sport II is priced, then designed and built appeal to the plinking community. The spec sheet and the build tell the story. The Sport I took too many short cuts. Too many other "plikers" had FA and dustcovers not that anyone who is just plinking needs either.
I think you are missing my point when you keep focusing on the 1/9 twist and a varmint rifle. My issue with the Sport as a varmint rifle is not its 1/9 twist. It is its 16" barrel and its stock configuration. If you are looking to shoot beyond 300 yards it is not your best choice. Can you do it. Sure. Is it the best tool no, I agree a bolt gun is better. Is it the best AR15 for the job I would also say no. Which was my point. Your red herring, assuming my issue with the Sport II as varmint gun, does not hold up. Again my reason for bringing up varmint guns was to show why someone might "outgrow" or "need" something more than the Sport II.
