When I look through a 3-9x40mm Buckmaster and then a 3-9x40 Monarch UCC I can't really tell any difference. My shooting eye is 20/10 but I can't tell any difference. The Buckmaster is 209.00 and the Monarch is 218.00. Need some help here from any of you who have an opinion they are a lot of scope for not much money, which one would you buy. Or for 429.00 I could get one Monarch SD BDC 3-12x42. All three of the scope are BDC and I want to put one on a Kimber 8400 Montana 30-06.
