func_50cal is a brush entity available in 
Black Mesa. This is 
M2 Browning (or Browning .50 caliber machine gun) that was used by HECU soldiers during the operation on the territory of the Black Mesa Research Facility. Can be used by player and HECU soldiers. This machine gun is also used in dm_stalkyard.
Note:The fire and deploy sounds are hardcoded. You still can change both in your Black Mesa mod by replacing the sounds with a blank sounds and playing your own sounds via input/output system.Note:The bullet particles is different in singleplayer and multiplayer, multiplayer particles are smaller.
Note:The original model for this gun is a bit unfinished. It doesn't have mesh under it (can be noticed in dm_stalkyard and bm_c2a5a). It also uses concrete surface parametrs, instead of metal surface parametrs.
Bug*:Must be combined with model. Otherwise, game will crash when this entity will shoot.Bug*:NPC's weapon breaks after this gun usage. It doesn't removes, but becomes invisible and unable to shoot (NPC still reload weapon several times, for some reason). This breaks the AI partially, because such NPC still thinks that it have functional weapon. This bug not in 
Black Mesa (the mod version). Bug*:You can find bug in dm_stalkyard when model doesn't rotates with gun position. The gun can kill controller at this moment, because it rotates 360 degrees at this moment. This seems to happen if you quickly press use button several times.
The bug example.

Note the gun muzzle position and position of the bullets.
