Designed for HK VP9 and Aimpoint's ACRO P1 and P2, OPF-VP9, ACRO is precision machined from 4140 steel and black nitride coated.

VP9 Tactical's taller suppressor height sights provide lower 1/3 co-witness with OPF-VP9, ACRO and P1/P2, but the front tritium/dot is partially obscured at the bottom. 

Steiner's MPS has a larger window size, the front tritium is fully visible through the MPS sight window.

Please NOTE: They will soon stop including the L keys with all OPF products, L keys will become optional, they strongly suggest a proper torque wrench to impart the correct torque value.
