I purchased an SH4 kit that came with medium halo rings. I mounted it on a CZ 457 MTR with an EGW 0 MOA rail. It seems high off the barrel. Can I use a lower ring?
How much of an opening do you have between the objective and the barrel? The difference of the Medium Halo rings @ 1.45", and the Low Halo rings @ .92", is .19", or just over 1/8". So as long as you have more of a gap than that, you should be fine with the Lows.
