The "SVDS 7.62x54R muzzle brake-compensator" and "SVDS Rotor 43 thread adapter" are both extremely rare to find in raid compared with the ubiquitous silencer part for the SVDS (the "Rotor 43 7.62x54R muzzle brake-compensator"), and the SVDS rifle itself which often spawns right in the hands of your Scav… but nobody can buy them until level Prapor lv3 and Mechanic lv3, at player levels 26 and 30 respectively.
Yet nobody seems to have noticed that a huge amount of the middling player base is blocked off from easily acquiring these rare and highly sought-after items that only cost pennies from the traders and can easily be flipped on the flea for 30-50k a pop or more to a captive audience.
Hot tip: the flea list on both of these items is empty 99% of the time. So start buying a handful of them and listing them on the flea at exorbitant markups. They may not sell instantaneously, but you can do it at the end of your play session when you've already sold off your high-demand item stacks and no longer need to keep both of your flea slots open. This overlooked trade is like printing money in comparison to the typical hideout craft & sell loops, and will likely remain so because most people level 26 and up will be too lazy to start replicating the trade even after reading this.
