Tikkas generally just work, but the problem is all the cool stuff you can get for them. I just picked up a couple of the UM short bolt knobs and put one on this afternoon. I’ve never been particularly fond of the small, slick bolt knobs on Tikkas. But all the replacement models I’ve seen prior to this were extended length, target versions that catch on stuff. This one is shorter than the stock bolt handles so it stays tucked out of the way, but the larger knob makes it easier to operate with cold or gloves hands. It’s a subtle mod, but a good one.
