I have Bushmaster xm-15 with the fixed carrying handle.  I wondering does someone make or can a flip down rear sight be installed if you remove the oem rear sight off carrying handle? Anyone that can steer me in the right direction would be great. The reason I'm asking is I like the handle and want to install a z bracket on handle and put a eotech in the lower postion. I don't have the money to buy a new complete upper. I could just buy the flat top body but I like the handle if I can make it all work together. It would be nice to look through the Eotech window without having to look through peep sight in rear. Thanks Scott

There are no flip up sights that will replace the assembly on a fixed handle. get a goosneck mount so you can mount the eotech in front of the handle or get a set of good railed handguards and mount the eotech on that.You could always cut off the large arperture so the small one would be the flip up should you need an iron sight and with no large no interference with the eotech.

I was wondering about that. I was told you had to look through rear sight to see the eotech? That it would not be tall enough? I have been trying to find a picture of what you would see, before I go and buy all this stuff. No one I know has this things! I'm the only gun nut. LOL Thanks
