Don't be afraid to make changes and then change again but try to only change one thing at a time so it's easier to solve the problem, changing 3 or 4 things at a time can and often does lead to a nightmare weekend of no shooting and two days on the keys.
I can see it will take time to get used to sitting correctly and like an idiot I thought that was going to be the easy bit
so my first change would be a rail for the mk4 and keep the high mounts is that correct
as that would put the gun in a more heads up position then adjust the hamster accordingly
