mounted on a 14.5 mid length with the surefire warcomp QD setup. zero shift on my LPVO was inside half MOA from cold bore to suppressed. tone is the typical surefire crack but back blast is manageable for an SOCOM can
Surefire SOCOM556-RC4 G4 5.56 suppressor has the fit and finish you'd expect from Surefire. Mounted to my Warcomp without issues. Suppression is in the expected range for a Surefire 5.56 can. Quality construction throughout.
