So I'm back in the AAP club after selling my Black Mamba build some time ago. Before I'd fired a shot, I installed a CTM FUKU-2 (great name, huh) trigger, which I really like the look and feel of. However I probably spent more time trying to get the perfect position on the overtravel grub screw, than it took me to actually get the trigger in there. I'm still not happy with the grub screw, especially as it's wobbly and I don't really want to screw glue it. Can someone explain "overtravel" to me and if I really need to use the grub screw?
I also don't know whether to keep the upper stock, go for another Black Mamba or a CTM two piece job (although IMO they're overpriced) ?
As much as I love the look of the Black Mamba, it did seem to negatively affect cooldown, quite significantly.
