Archived [ARCHIVED THREAD] - Ejection port cover question
Posted: 11/11/2003 8:37:13 AM EDT
Could you chamber a round, close the ejection port cover, and fire the round without the rifle jamming?

It seems that the bolt carrier would just open up the ejection port cover on it's way back.  It seems the ONLY way it would jam is if you were operating on the edge of reliability (getting just enough gas to cycle the action) and that tiny bit of extra resistance made your rifle short stroke.

Anyone try this?

Chamber a round, close the port and then fire? Sure it just pops open. No biggie.

That is what happens.  It is designed to fire a chamberd round while being protected buy the dust cover.

Correct. That is what the little groove on the side of the B.Carrier with the two little holes is for. The "Knob" on the inside of the Cover fits in there and the groove pops the door open when the bolt is pulled back or moves forward.

Keep your ejection port closed at all times.  It keeps debris out of the action and is another tool to ensure reliability.

Thank you everyone for your responses.  This is what I thought.. just wanted to make sure.
