High Standard AR-15 anyone?

[RTFM]

Local gun guy has gotten in a few High Standard AR-15's
Specifically the HSA-15 FLAT TOP CARBINE HSTX6551

Anyone know much about them?
Tried a few online forums for info and it appears to be scarce.

Thanks.

The shop I frequent had some HS lowers & the owner told me that these are nice lowers & equally nice complete builds. If you get a good price...don't worry, just enjoy your rifle
