Thickness comparison 556 & 551?

[Seanski]

Is there much of a difference either visually or pocketability in the 556 and
the 551? I am wondering if there one notices one over the other in pocket?

thanks,
Sean

Steven,

Thanks very much for those shots! It was exactly what I was looking for. The 556 is quite a bit thinner than the 551.
