Base weapon. Total TTK = Sprint to Fire Speed + ADS In Speed + Avg TTK + Missed Shots, the same as on the Meta page. Avg TTK is the expected time to kill with shots spread over the body (Body Mix by default, change it under Hits), averaged evenly over the distance range; a One Shot distance counts as 0 ms. Each attachment shows its own changes to the base weapon: green = better, red = worse.
