1 Lower 2 uppers same scope?

[Ron Padilla]

I am in the process of building the 300blk upper, the lower is complete, last week I had to make a few things happen to come up with some money and sold my 308 for some cash a upper and a 9mil.  So my question is, will the scope stay in relative closeness to zero when going from one AR upper to another or is the general consensus that I will have to re-zero going from one upper to the other.  Thanks in advance.

You'll have to re-zero. Yes.

yes you will have to re-zero, but it will be real close. I have done this before as well, and it was just a couple of clicks off.

Thanks for in for the info, as more money is available, I will probably get another lower to build out so that it is 2 dedicated rifles or get another scope, which ever I can afford 1st.
