Just got a sidewinder. Was coming from HHA and the reason I went this route was simply dropping as much weight as possible. I think this sidewinder weights like 7 oz where my HHA weighed like 1.7 lbs. I like it for what it is. The pin is super bright, which is something I've always known about Viper pins. I really don't care for the sight tapes and probably won't use them. I'm getting older (not old yet, but older) but for some reason visually they just seem to blur and blend together. So far I've just got marks on the blank tape that came on the sight and that's prolly what I'll stick with. Going to this sight though really made me realize how nice my HHAs and other sights were though that had micro adjustment features to them, as this one does not. Overall I'm happy w/it for what it is and what I expected out of it.
