Great Ejection Port Cover
by Mac Conway
I only use the most quality parts. That being said Ive these thick cover on several Noveske upper and they work great. I haven't experienced any of the problems the other 2 guys are bitching about. Sometimes polymer is a little out of spec becuase of the molds. They should of contacted KAK and they would of replaced them for free. Live and learn.
Waste of time and money

As the other reviewer stated, it does not work. The plastic is too thick, I fixed this with a Dremel. Closing detent. could not fix. Threw it away.
This is a spectacularly bad product.

I tried this unit on two different upper receivers, PSA and Aero Precision. Same problem on both. It doesn't fit well, to put it mildly. Way too thick around the axis where it's supposed to spin against the receiver so you get a ton of friction and the little spring is powerless to budge it. Plus, the locking detent sticks too far up so it won't close unless you press that down with a pick. Then, once you get it closed it won't open because the plunger is up too high inside, locking the cover firmly in place. Once closed it freezes your BCG up completely, rock solid.
