Here’s my issue with Ruger, the 77/22 .Standard is $542 on Buds, the CZ 452 American is $366. The CZ 453 American with SST is $489. The CZs are as good (some may argue better than) as the Rugers but provide an outstanding value. And there's no way anyone can say the 77/22 is that much of a 'better' rifle.
To the OP, it seems you have your heart set on the Ruger, and that’s fine. The rifles have no sights to accommodate a scope. I have no idea where you can get a 77/22 with sights but a CZ 452 Lux on Buds sells for just $366 – it has the best iron sights in the business and as noted is very accurate. If you can’t find a 77/22 with sights the CZ Lux would be your next best bet.
