I might be wrong but, I’m not aware of any factory made LH bolt-action rifle offered in .223 with iron sights other than the now discontinued CZ 527 Lux. 🥴🤷♂️ I happen to have one and I can tell you it’ll never be sold during my lifetime.
Beyond the CZ mentioned above, your only other options may be a Zastava M85 or potentially an older pre-accutrigger Savage (dunno if this one exists though).
