Welcome to the site.
Lefty; eh? You're in good company here - several lefties here (including myself).
I've got a Stag 1L too and love it. I think you'll be pleased with your choice. If you ever look to swap out your ejection port dust cover with an engraved cover you'll need to be aware that it sits on the rifle upside down from normal covers and the same goes for when it flips open. Standard engraved dust covers won't work like with a regular AR, it needs to be engraved upside down (guess how I found out about this).
Okay, I have to ask about your handle/userid... When I first saw it I was SURE you were a spambot account, not a legit member. What does the handle mean?
