Go with Oakley eyeware, hard case-you're spending alot of money, get a good sling and use BCM charging handle #4-medium. Sounds good, get plenty of ammo and have fun, take some carbine courses
Good eye wear and hearing protection is a must, and is well worth mentioning. WeaponEvolution.com and Military Times are starting a review of new eyewear, but its a project that is going to take months to complete. I'll post more info about it in its own thread.
