It surprises me that you didn't notice issues zeroing, especially since you are running an Arms rear BUIS. The Arms #40's that I have used, seem to be a bit higher than they should be, requiring that I run the FSP out a lot more than with a normal height rear BUIS. I've even had to run a +.040" FSB on "F" marked FSB's, with those silly Arms #40's before. Wierd.

I like that carbine, Eric! I am changing out an A-1 upper on my daughter's 16" SLW, to a flat top as we speak. I plan to run a DD A1.5 rear sight on it. If the parts get here this weekend, I'll get it together, and get a pic or two.

are these really 2grand? why?

No. They are $1199. Early serial numbers were more.

a member of arfcom just got his 6720 and came w/o the F-FSB....
maybe Colt will put it once they start a full production

I wonder if he couldn't see the "F" stamp, or if Colt just cheaped out...

mmm...good question...
I cant visit arfcom at the moment but if you take a look in the Colt forum you'll find his thread
