This is certainly an FAQ, but for some reason I am having no success using the search function today.
I'm a long way from building an AR pistol, but I am trying to read up on them. I'd like to find out what the current state of the art is for pistol buffer tubes & buffers, specifically for 5.56 and 6.8. For example, I see pics of everything from rifle length to some pretty abbreviated tubes. The short ones sure are appealing for portability and concealability, but I read somewhere that the shorter tubes aren't all that reliable.
If I were to begin the shopping process for an AR pistol, probably in 6.8, what should I be looking at for buffer tubes and buffers?
thanx
