CIL Anchutz .22 model 780...

[catnthehatt]

The CIL-180 is an Anschutz model 1402-A,,, too bad your stock has been hacked in order to accommodate the rear sight.
There are factory drilled and taped holes on the left side of the receiver, but,the factory sights are the best on this gun

For a while the 180 was available for less cost with a Redfield Olympic sight that is also a side mount .
the sight is mounted with an adapter plate , but the stick did not need to be cut to install it .
