No.4 Mk.1 scope recommendations?

[jonh172]

A fixed power scope will be best, 4 or 6 power would be ideal for your desired range.
Fixed power scopes will have the best glass quality for the price, plus are more robust with less internals to break.

Try not to pick one with a very fine reticle as it will become "lost" when viewing through brush or in low light or both!
