are their "low profile" the ones called "express?" i really like these (at least the looks). if you mount a sight on your receiver, i assume you must remove the factory sights. i didn't see any of their sights that fit on the barrel, but i must have just missed them. which are your favorite overall? (looks, function)

and thanks seagoing! actually, i had just came across these in a search last night. now their site is down....typical luck for me

i think the express model looks very nice, probably the best looking option i have seen. seems to get good review on function as well.

the one thing i am concerned about is the replacement of the front sight. there doesn't seem to be any reference like..."this front site goes with this rear sight"....it all just seems like maybe, this will work, maybe not.

thanks for the info on the forum as well, i'm sure that will help a lot!
