example : MP5 -> handguards, rails, silencers, muzzledevices, everything

AS Val same thing – mounts

literally all decent barter item trades (lost alot of possible good trades by selling stuff that is actually top tier barter)

And so on, hope the search function will get some love 0.12, maybe you could CooP with the gamewiki,

they have a very detailed system and iam sure they would support tarkov.

Edit:
As everyone commenting the same, to go for detailed searching on the upper reciever

Yeah, that might be the case, iam not saying you are wrong, but it´s different on many guns anyway, the way it is now, and the solution isn´t very QoL improving, it´s the opposite.

not to mention the barter search unusability.
