I have a $30 NCStar reflex on mine--from Amazon. It has been a heck of a lot of fun--more so than I ever thought it would be. The only gripe I have, is that I need to keep adjusting it to keep it on target maybe every hundred rounds or so--no matter how hard I tighten the adjustment screws.
For perceptive, NCStar supposedly does the OEM manufacturing for some otherwise identical scopes that cost 2 and 3 times the price.
Unless you are some sort of serious competitor, or unless your life depended on the scope/Browning combo, I can't see spending more money on something else.
