Nope! It's the basic engineering. The AR is ALWAYS going to be the more accurate platform due to it's design/engineering.
Besides, the first thing you do to make a consistently accurate rifle is to toss the wood into the fireplace and replace it with some flavor of plastic/composite....even the stuff that sorta looks like wood (laminates) are primarily plastic, or as close to it as the materials people can make it without going to 100% synthetic materials. Wood is something pretty you sit on, not make a firearm out of...just go to a real marksmanship competition and you'll be able to count the "pure wood" furniture on one hand! IMHO, a "pretty" target is infinitely preferable to a "pretty" rifle....in over 45 years of active shooting, most of it in some flavor of competition, I have YET to see a target that was the least bit impressed by the appearance or pedigree of the firearm shooting at it!
