A4 optic mounting question

[sammy]

A quick AR question. I have an older EO Tech that has the ARMS mount. It is on an M4gery with standard handgaurds. Is there a mount that will allow the use of a BUS with this optic? The EO Tech uses all of the mounting surface of the Rock River I have not. It would be nice to be able to use irons for practice. Thanks, Sammy

Something like the eotech 553 them? I don't think so. Unless you got some sort of riser that extended forward past the delta ring, but then you'd be raising everything.

edit: Maybe something like an a.r.m.s. swan sleeve? http://www.armsmounts.com/default.as...d=[hsh]38%20Ex They have a few different models, with and without the sight built in, and different lengths.
