That's about it. That's why there's a rule for a maximum of 1.5" for the scope tube above the action, because it is supposed to be a sport related to hunting, and they don't want people getting ridiculous about it. This is also why they have a jig that your rifle is supposed to fit into, so that the dimensions still resemble a typical hunting rifle. High rings right up around the maximum allowable height definitely make a positive difference. I have the high variant of Burris Signature rings on both my silhouette rifles, a CZ 453 Varmint and an Anschutz 1712. To see whether or not I would like having rings that put the scope kissing that maximum height, since it is so common to get right up against the rule for the top shooters, I figured I'd 3D print some rings that meet the rule and give it a try. It definitely is a lot nicer!
The 3D printed rings aren't suitable for normal use. They didn't hold zero well, but they were sufficient to give the height a try. I haven't gotten around to it, but I do want to replace the rings on both rifles now with max height ones. I've also thought about having some produced by a 3rd party since we have so much trouble getting anything in Canada, but the cost involved wouldn't make any sense. At least, I'd be fine with the cost for my own sets, but I don't think anybody would then pay what would be necessary for it to make business sense. We need to find a Canadian with CNC machines to start making them, hehe. I mean, even getting a company like PCBWay to make them would be sufficient, even if their tolerances aren't great, because we can use Burris's Pos-Align inserts to sidestep having to have nice tolerances.
