SOCOM 2 Series Suppressor (Mini - Skinny Remix)
This is a remix of the 'SOCOM 2 Series Suppressor' by 'Recticle'. Specifically, it is the "Mini" size that is available in the downloads over there.
I printed it as a non-functional, decorative addition to my airsoft gun, but unfortunately, it was too wide/fat to screw onto my barrel and fit into M-LOK handguard. So I just made it a little bit skinnier.
