I have a HS stocked .338 Lapua and need to know if a 56mm bell on a Nightforce NXS, with a EGW one piece base will have enough clearance using LOW Nightforce Ultralight rings? It suppose to be a 20 MOA base, but it does not look like it? I have an early .338 L that many had questioned if the bases were really 20 MOA or not? Anyone have this setup? Thanks!
