My son has this rifle. Your price OTD is about right (I don't think it's a steal - but about average street price).
Yes - if you put see-through mounts on it you will be able to use the iron sights - but it depends on the mount as to 'how much' you'll be able to see. In looking at his rifle, we went through the same thoughts and determined they'd have to be pretty high mounts to make the irons viewable. Please note these are our thoughts based on how we shoot, etc. YMMV.
We (as a family) have purchased 2 10/22's in the past 3 months and this particular model is the best. Stock is great allowing you to use American Rimfire stock inserts and the feel of the American style stock is just grand.
Buy it - you won't go wrong. Give it a good cleaning and lube before shooting and check that all the sight mounting screws and stock screw are TIGHT - his were all loose from the factory.
FYI - his shoots ragged holes at 25 yards with the iron sights with American Eagle 38 grain ammo. CCI 40 grain standard velocity ammo opens up just a bit. It's a shooter and he's quite happy with it.
