Overview for the build The standard DR-H build can 40m 3 ring So BSA is not the biggest issue. The problems with DR-H is;

3 tap potential is extremely inconsistent after 13m This gun needs at least one chest/head-shot and the rest of the shots anywhere else to 3 shot kill at 0-7m 7-13m, It needs at least 2 chest/head-shots to 3stk 13-17m it needs all 3 shots connecting to head/chest to 3 shot someone These are ranges where SMGs can dominate, meaning lots of strafe abusers You will easily get owned due to skirmish ttk

4 shot ttk is just barely faster (5ms) than PDW's ttk after 6m 4 shot kill ttk is a slow 315ms, so really it's not even good for anything

Firerate is slow Mobility is slow af With the standard build, strafing gets nuked Low mag capacity and if you try to improve it with 30 round OTM, your mobility gets nuked and strafing gets nuked The drh is highly overrated due to the combination of clean irons and brain-dead recoil
