In my opinion an AR is every bit as tough as a Mini-14, and will outshoot one any day of the week and twice on Sunday! Abuse is the key word, I don't abuse any of my guns. Stag makes a good weapon, and you will never wear it out under normal use. Make sure you keep it lubed, (AR's do not like to be run dry.). Break-free CLP has been a good choice for years, these days I use Slip 2000, but any lube is better than none. Get a few Magpul magazines, and you're good to go. Have fun and let us know how it shoots!
