Effortless and reliable 0.800-1.100 TTK at 100m, so this thing can definitly compete with MXR-17 at long range, however the MXR-17 stands no chance at close range against the M15 Mod 0 since the M15 has 2nd fastest TTK of all assault rifles at 0.584 TTK, good enough to even out TTK the CBRS-3

M15 Mod 0 is the truest best Season 5 meta assault rifle that everyone is sleeping on.
