Wow fellas, thanks to all who replied. All great sources of info and good advice, Im sure. Sounds like the concensus is that a factory one is a better pick for a first rifle? I'm pretty savvy in the workshop, but Im not a gunsmith. Im actually just looking for a fun shooter for range/tact. shooting (5.56 NATO/.223) I was actually aiming at a carbine to begin with. Mil spec isnt that important to me.
