So my BCM midlength just showed up. I mounted a Daniel Defense A-1 style sight on it and set out to zero it today. Although I think I've got it pretty close now, I feel like it took way too much adjustment to get it there. My first group at 50 yards was about six inches to the right. I had enough room in the sight to get what I think will be a close enough zero to fine tune at 100 yards but my rear sight is adjusted far to the left now. I'm a little concerned that I either won't be able to get it zeroed or that if I want to try different ammunition I won't have enough room to zero with it.
So what's normal? What's in-spec and what isn't? Any insight would be appreciated.
