this is the whole thing, wouldn't want anyone to get the wrong idea would we Doc.
"What do I recommend for a 3 gun rifle?
Obviously if you are a world class shooter you are not reading the FAQs but if you are just getting in to it for recreational purposes then if the shots are 0- 300yds a lightweight 16-18" .223 with a midlength gas system and a light carrier and buffer tuned to work together. The twist would depend on the bullets you plan to use and any other uses you may have planned for the rifle. I like a EO Tech sight they seem to be a little faster to locate the targets and I usually have no problems connecting on targets out to 300yds. If you happen to shoot longer ranges you may want to consider a ACOG or a low power scope with a wide FOV. If you shoot smaller local shoots and they do not use flashers and the RO relies on sight and hearing the ding then a 6.8 could clarify those judgement calls when the steels are out at 200yds or more.
