We have a single domain AD with three sites, one DC
in each site. We use AD-integrated DNS.

I've noticed that there are some duplicate A records.

There are three for the domain name itself, mapping to
the addresses of the three DCs. And there are three for
the domain name preceded by gc._msdcs., also mapping to
the DC addresses.

I thought AD used SRV records for locating servers?

Yes, and this is correct but A records are used to handle requests for
domain name like \\domain_name
