I think your buddy needs to follow the Manufacturer's reccomendation and RTFM before playing with his new toy! Believe it or not, those little books often have some good, useful information in them. I hope he hasn't purchased any ammo for that puppy yet. :roll:

Wait till the first time he field strips it and then re-assembles it with the rear take down lug matched up to the forward pin, what I call the "Kentucky Long Rifle AR." :mrgreen: That's always a hoot to see.
