You could just switch to an M1A.
My brother, former Marine infantry with two combat tours in Afghanistan and Iraq under his belt, preferred the AR when he got home. He decked it out...put like $2,500 into it and accessories. Last year, he traded it for an AK. Loved the AK so much more. Right around Christmas, he bought a Springfield M1A. He could barely talk straight to me he was so impressed and excited after shooting it. He couldn't stop talking about how pleased he was that it has both accuracy and that increased power of a .30 cal. He has made it his go to rifle, and is going to sell his AK.
I wouldn't be saying all this in this manner, usually, but my brother is the real deal. He's no SEAL, but he has mastered all the basics a rifleman needs to know.
Just food for thought. Do what you want. ;-)
