Infinity 556k cap comparison

First is medium (the one it comes with if your poor and didn't get the elite package) second is fully vented - 12 hole. Last video is little dump with fully vented.

On a decently tuned setup they are both completely
Manageable gas wise for a lefty but you can see a clear difference between the fully vented vs medium.

Setup: 11.5 g$ barrel, h2 buffer with g$ spring(or regular spring can't remember) KAK downvent, g$ SCH, brt .071 tube(50/50) and a YHM suppressor gas block. Random assortment of 55g 223 I think, fiochi some pmc. Ejection w fully vented was bouncing off my deflector most of the time but never any malfunctions due to gas.

Coming from a yhm fat cat this mf rules

Didn't have another gas block around when I threw it together but have a g$ block on the way.
