On the 2nd 77 ( Bigtoe tune ) I removed the Venom latch and refitted a standard one. I just use the little threaded hole at the top ( front sight ) to run a grub screw through and hold the unit onto the barrel. So I can adjust that forwards or backwards. I also like that as I can remove it in seconds and fit a barrel sleeve/weight behind the standard latch. I can move the weight backwards and forwards or try different weights by using grubs to fix the weight where I want it. Well that's the plan anyway ... but that's just started work in progress.
I also like that set up as it brings weight back, which for me, a dwarf, feels better.
