About the brand · RR-ARMS

RR-ARMS – a vz. 58 receiver cover that actually holds an optic

RR-ARMS is the Czech brand of Ing. Rudolf Rychlík. We dare say we have sold more of his receiver covers than anyone in the Czech Republic, and with zero warranty claims in all that time. We carry four items: the KR58 PRO CNC – a machined receiver cover for the SA vz. 58 with a Picatinny rail that replaces the original stamped cover and carries a red dot or scope without losing zero; the KR58 PLUS – the same with a side mini rail; the standalone 58MINI side rail for retrofitting to a PRO cover; and the RR74MINI, a red-dot rail for the AKS-74U "Krinkov" that you will not find elsewhere for this gun. The cover is machined from 7075 alloy, and the original iron sights remain usable with an optic mounted.
