This is PSO-1 Reticle for the Vintorez/AS-VAL, weapons from this mod Spetsnaz Rifle – Standalone Rifle by undyne777.
This mode is just a tiny rework of this mod Modern Scope Reticles – Scope reticle overhaul by Zeyphir
It will change all the reticles of long/short (normal and recon) scopes even if you don’t have “Spetsnaz Rifle” mod installed.
