[ARCHIVED THREAD] - Cav arms lower help needed

Posted: 4/9/2011 6:49:16 PM EDT

I have a CAV arms lower that I have replaced the FCG twice. (One was a DPMS and the second was M&A LPKs)
The problem I am having is when I have a 223 BCG in it doubles up. When i switch over to a M261 BCG it works perfect.
I changed out the FCG thinking it might be a problem with a part from there but there was no change.
Any help would be appreciated.

Thanks

When you say it 'doubles up', do you mean its double feeding or firing two rounds?

It fires 2 rounds.

Does it only double fire on the firing line or does it fail a function test also?
