[ARCHIVED THREAD] - Colt 6920 FSB ?

Posted: 7/30/2011 7:41:11 AM EDT

Are all BUIS the same height? I want to pick up a rear that will work with my LE6920 that has the FS on the barrel.

Thanks

Pick up a Matech buis, it works very well with the 6920 FSB.

I'd suggest a Daniel Defense rear fixed or Troy rear foling sight.

To answer your question, almost ALL rear BUISes will work with the Colt FSB. The only ones that wouldn't, would be labeled as being shorter––micro height for HK416s or raised top rails or something. Any standard one from YHM, DD, TROY, MAGPUL, ARMS, MATECH, KAC, etc., will work.

My ARMS 40 works just fine with a 6721 FSB.
