i'm helping my friend put together an M4gery, and i was going to just go with an RRA complete lower, but i was wondering what lower can i buy complete that is going to be closest to the service M4s? (minus the happy switch ) because i know some stocks are 6 position i think, some are different. thanks guys.

They are all going to do the same thing, if he wants a military looking M4, tell him to sign up like the rest  
of us did.

If he wants a certain looking stock, have him pick it out.  Besides, if you are helping him, he should be buying the lower to avoid a straw purchase.  


RRA uses a slightly different buffer tube than the mil version, which isn't an issue unless he plans on dropping a different stock on.  If he does, have him get it now to save money.

actually, he did sign up about a week ago. he's going army, altho i question his reasons for signing up. sounds like he just wants to be in for the cool factor and getting a gun
