I recently acquired a new Rat 2 in D2. My AUS-8 Rat 2's lock-up is right about the 50% mark. My new D2 Rat 2's lock-up is pretty much at 100% and it looks to me like the only reason it doesn't go farther is because the detent ball is hitting the opposite liner. Is this normal on the D2 models? The lock-up is tight (for now), I'm just concerned there is no room for wear. Thanks.
