CZ452 11mm to Picatinny rail

Looking for options to replace my BKL 11mm to weaver rail on my CZ 452 Varmint. The BKL’s are a bit high so looking into replacing em with a single piece, lower rail.

U.S. OPtic’s one piece rail, uses thee screws to mount
.

Rimfire Technologies one piece rail, uses six screws to mount
.

Using these now: BKL two piece, four bolt picatinny rail. BKL makes a one piece rail, but it is high also.

If you know of other quality made picatinny rails for the CZ452 varmint, would like to see them also. Leaning toward the U.S. Optic’s now?
