Please forgive my AR ignorance, but I don't know much about them, other than shooting a few of the M versions in the Navy. I've been meaning to pick one up for a while now, and I think it is about time. I was going to get a Bushmaster, but this thread has convinced me of the merits of the Rock River. Now I just need to figure out which configuration will be best. I want an M-4 style weapon, so I've narrowed it down to the Entry Tactical or the Tactical CAR A4. The only visual difference that I noticed between the two is that the Entry Tactical has an R-4 barrel profile. Since I won't be mounting a grenade launcher, what is the purpose of the R-4 barrel? Is it merely cosmetic? The other question is which barrel to choose. I see my choices are Chrome-Moly 1:9, Chrome Lined 1:9, Chrome Lined Lightweight 1:9, or Chrome Lined Lightweight 1:7. Which is recommended? I'll probably use the rifle for nothing more than pleasure shooting, and it will probably see a lot of use. Any tips are appreciated!
