Joshua, I like them because they lessen the over-all weight of a rifle and acts as a great counter-balance. Ex: a long gun like a Diana350/B-28A. Another thing I like is it's very close to using the 'irons'. Not as easy to line up9for me at least), but once done, it'll give you a decent quarter sized accuracy in the 30 yard range off-hand. Forget the low end Crosman/Daisy RD's. A good one to try out to see if you like them is the Tasco's sold at Wally-World for around $40. I hunt and plink more than I paper-punch, so I rarely ever crank up the magnification for my purposes. I say give the RD's a 'shot'!!! LOL's Best Wishes, tjk
