Here is a scope you may want to look at, a Nitrex by Weaver TR2 4-20x50mm side focus with pullup target type turrets. Its discontinued, so price is reduced and Nitrex has a $100 rebate on this scope that has been extended till March 31. It is basically a Weaver Super Slam scope, same optics and internals and with rebate the Nitrex version is less than 1/2 the price. Japanese optics in it is darn good and adjustments track well. Have 2 Nitrex TR2s and my fellow shooters at range have been very impressed with its glass and features. Only two complaints I've read about the Nitrex TR2s is the weight...on heavy side so not the scope you'd want for a light carry rifle. Also, Nitrex has one illuminated reticle model and some complaints posted on problems with the illuminated reticle not working. Other than that, its buyers like me have been very satisfied with the scope. By the way, Nitrex has a lifetime warranty and Weaver will handle it since Weaver and Nitrex both owned by ATK, a company that also owns Speer, CCI, Alliant, Outers, Federal Cartridge and etc. Here is only website with this scope to sell where you can get the rebate too.
