Good price for Bushmaster?

[Frog48]

A local sporting goods store has Bushmasters for $854. The model number is XM-15 E2S. Does this sounds like a good price?

 

[648E]

New?

Yes, that's cheap.

By the way, all the metal ones are XM-15 E2S as far as I know.

 

[Frog48]

Yes, brand new.

Maybe a stupid question, but... On the Bushmaster website, some say they have a "Bird Cage" flash suppressor and others have an "Izzy" flash suppressor.

Whats the difference? I cant tell any difference, based on the pics on their website.
