HELP!  I like the iron sights and red dot on my M-4 profile AR, but I am looking for a way to mount my cheap Bushnell scope, which would be used only once in a while.  I want to be able to take it off and put it back on without having to re-sight it in every time.  I currently use cheap 1" mounts and it goes on and comes off readily enough but there is WAY TOO MUCH play in the mounting on the flat-top for it to be reliable.  I AM cheap, if I'm going to have to drop $150 for scope mounts for a $50 scope then I guess I'll pass.  I just wondered if I am overlooking a suitable product that would solve my problem without dropping $$$?

Looks like that is the answer I've been looking for!  Thanks, Mike!

Is this cheap enough for ya.  I'm embarrassed to say I have one of these suckers on my truck gun.  I have a cheap Simmons red dot mounted and flip up irons.  The cool thing is that I can use the irons through the red dot, the dot even co-witnesses with the irons.  I haven't tested it for repeatability though. Its not in the ballpark of my Larue scope mount that I use on my other AR, but it does seem solid with a good tight fit.

YEah, that's cheap enough!  Thanks for the tip!

Hope you have a buttload of cheap ammo. You are going to need it.

Mike,

Do you have a link to these?  How repeatable are they?  Any still left for sale?

Thanks.
