Concordia security room is an awesome place to get your Gunsmith rare parts. It hides a lot of attachments that are not usually found in gun crates. So if you are struggling to find, per se: M14 UltiMAK M8 Forward Optic mount AK Zenit RK-3 pistol grip Magpul PRS GEN3 stock Stark SE-5 Express Forward foregrip AR-15 Naroh Arms GRAL-S pistol grip And so on, you should really consider looting this room... I hope you enjoyed the video. If you did, please leave a comment, and I'll see you in the next one! Location of the room: https://www.youtube.com/watch?v=xrEE2VK8Juk #escapefromtarkov
