Mike, David just made the best suggestion of all the replies IMHO. Like David, I have two Cloned Diana 350,.....except mine are B-28's. In pure stock form, they are a vicious, and merciless weapon that will bust any scope in no time. Best to tune this monsters asap. You'd be amazed how much better they shoot after something as simple as a deburr/lube tune. My .177 is all stock, and is by far the fastest and hardest hitting magnum in my collection. But it is tuned, and deadly accurate at 30 yards. With that in mind, you said you wanted a scope but didn't want to pay a fortune,.....I'm partial to the Center-point scopes from Wal-mart. Sure they're not the best scopes available,....I have better ones,...but for a rifle such as the B-28,...they are more than adequite. Both of my B-28s' sport a CP 3-12X40 (size ?!? Maybe 42 mm) on a UTG comp. one piece mount. What I like about them is that the turrets have a 'lock-down' ring that helps keep the rets from vibrating out of zero. Nice clear window with plenty of FOV. The rets are fine, but I don't fool with the illumination features much at all. HTH, tjk
